gas source changes. Most commonly, these purge assemblies are
used with pressure control devices as an integral option or can be
used within gas delivery systems to isolate pressure or flow control
equipment.
The 502 Series purges are offered in brass and stainless steel.
Brass and stainless steel purges are offered only with diaphragm
valves. Optional testing can be provided to certify these purge
assemblies are helium leak-tight for the most demanding services.
These devices are intended for use with chemicals that are com-
patible with the listed materials.

Regulators for Very Low Delivery Pressure

Dual Stage Cylinder Regulators For Very Low Delivery Pressures (Model TSC)
The Model TSC Regulator provides highly accurate pressure reduction of inlet pressures up to
3000 psig down to delivery pressures as low as 0.3 to 3 psig. The dual stage design provides
constant outlet pressure regardless of changes in cylinder (inlet) pressures. The Model TSC is
suitable for use with non-corrosive gases where high puirty is not required. Typical applications
include low pressure purging, inert blanketing of chemical or flammable storage units, or control
of fuel to burners.

These single stage, piston style regulators are designed for non-corrosive gas service and
have proven to be satisfactory for use with low level corrosive gases (less than 100 ppm)*.
The control valve permits constant gas flow and easy on/off capability. Each regulator comes
with a cylinder pressure gauge and is available in seven preset flow ranges. This series of
regulators is for use with non-refillable cylinders using a 5/8" - 1/8 UNF C-10 valve.
* Low level corrosive gases slowly react with the “wetted” brass parts of the 500 Series regulators.
In order to minimize loss of calibration accuracy, the regulator must be removed from the cylinder
after each use. Praxair’s 6000 Series regulator (page F34) is recommended for extended use with
corrosive gas calibration standards.

Critical Purity Switchover

The 522 (Brass) and 523 (316 Stainless Steel) Series high purity
automatic switchover systems are designed to provide continuous
supply of high purity gases to the laboratory, process or instrument.
The system automatically changes cylinder or bank priority from
primary to reserve with no fluctuation in line pressure to provide a
continuous, uninterrupted supply of gas to the process, laboratory
or instrument. Each system may be ordered with internal pressure
switches and a power supply/remote alarm to provide both local and
remote indication of bank status. Each power supply/remote alarm
will operate up to four systems. For use with flammable gases or in
hazardous locations (class 1, division 1, groups A,B,C, or D) optional
intrinsic safety barriers are available. A second option is a telephone
dialer which will signal when a bank is empty. For handling toxic or
poisonous gases, the 523 Series is available with optional Automatic Switchover shown with Remote Alarm

Bulk Gas Delivery Systems

Praxair is revolutionizing flow rates for ammonia as well as many
other specialty gases. Our patented system significantly reduces the
number of cylinder changeouts required by conventional systems –
leading to improvements in uptime, production costs, more consis-
tent purity, and most importantly, safety.
The proprietary Praxair enclosed heating system allows higher flow
rates while maintaining controlled external tonner temperatures. The
system can be skid mounted to facilitate installation and movement
around the facility. It delivers continuous ammonia flows of 600 slpm
with peaks greater than 900 slpm.

Sulfinert™ and Silcosteel™ Treatments

Stainless steel sample cylinders (pressure rated to 1800 psig by the

Department of Transportation) commonly are used in the collection
and analysis of refinery and natural gas samples. These samples
often contain trace amounts of sulfur-containing compounds (e.g.,
hydrogen sulfide, mercaptans, and sulfides), which may interfere
with reactions or damage catalysts in many petrochemical pro-
cesses. Because sulfur compounds are quickly adsorbed by stain-
less steel surfaces, accurate determination of these compounds is
impossible when using untreated sample cylinders.
Restek’s Sulfinert ™ passivation technique bonds an inert layer to the
surface of the stainless steel. Most stainless steel products can be
treated with Sulfinert ™ passivation, including tubing (see Table 1 for
recommended bending radiuses of tubing). Because the Sulfinert™
layer is incorporated into the structure of the stainless steel, treated

1-877-PRAXAIR
surfaces can be bent without affecting the inertness characteristics.
This layer acts as a barrier preventing active compounds from
reacting or adsorbing to the stainless steel. Therefore, Sulfinert ™
products are ideal for the storage and transfer of reactive sulfur-
containing compounds.

Thermal Gas Purifiers

Introducing Restek’s line of re-engineered thermal gas purifiers.

This line of purifiers works by producing a chemical reaction between impurities in the
carrier gas stream and the getter material. Because the reaction is non-reversible, there
is no possibility of contaminants breaking through the thermal gas purifier.
Gas purification is very economical when using a thermal gas purifier. After initial
installation cost, getter tubes only require changing once every year; heavy use and
very impure feed gas may require more frequent getter tube replacement.

Features and Benefits

■ Removes oxygen, water, carbon mon- ■ Welded end-fittings on getter tubes

Super-Clean™ Gas Filters

Restek’s® line of Super-Clean™ gas filters is the latest in cartridge gas filtration. Cartridge
systems make changing gas filters quick and easy. The system uses a baseplate that allows
cartridges to be exchanged without introducing oxygen. Spring-loaded check valves seal
when a filter is removed and open only when a new filter has been locked in place. There is
no longer a need for loosening and tightening fittings every time a trap is changed, and your
system will not get contaminated during the process. Also available are 2- or 3-position
baseplates, you can purify all GC gas streams at one location. Any combination is possible 2- and 3-position
because any Super-Clean™ filter cartridge can be used with any baseplate. baseplates

Gas Specific Purifier and Contaminant Traps Purifiers

Gas specific purifier modules are designed to be placed in-line with

the Gas Chromatograph (GC) carrier gas supply or the GC detector
gas supply. There are three groups of contaminants that impact gas
chromatography: moisture, hydrocarbons and oxygen. The Gas
Specific Purifiers remove the three contaminant groups from analy-
tical gases prior to entering the GC. Proprietary absorptive materials
capture and retain contaminants for the operating life of the purifier.
The new gas specific purifier modules offer dramatic reductions in
most contaminant levels (from many parts per million to levels that
are below the lower limit of analytical detection) and absorb a larger
number and variety of contaminants than other competitive products.
The performance is optimized by incorporating a multiple bed form so
that each successive bed functions at a lower contaminant concen-
tration. The result is a series of contaminant concentration gradients Inlet gas containing oxygen, High purity
across the length of the purifier module. When these advanced ma- moisture and hydrocarbons outlet gas
terials and design features are combined with a known gas contami-

nant concentration, the following performance should be achieved.

Gas purifiers are designed to help insure the purity of your analytical
gases at the point of use. Even though you may be purchasing ultra-
high purity gases, your delivery system may be compromising the
level of gas purity you require. The best way to make sure your instr-
uments are receiving the highest level of gas purity is to utilize point By combining several beds of specialized sorbent materials, a contaminant

Hydrocarbon Trap

Praxair’s Model SG6130 Refillable Hydrocarbon Trap is designed to

remove trace levels of organics from carrier gases such as Helium,
Argon, Nitrogen, Hydrogen and Air. The Model SG6130 is packed
with a baked coconut shell based activated carbon to effectively
remove alcohols, aromatics, chlorinated hydrocarbons, ethers,
hydrocarbons, ketones, mercaptans, and organic acids. SG6130 Hydrocarbon Trap

Disposable Oxygen Traps

Praxair’s SG6160 Series Oxygen Traps are designed to remove trace

levels of Oxygen from carrier gases such as Argon, Carbon Dioxide,
Carbon Monoxide, Helium, Hydrogen, Methane or Nitrogen. These
traps are also ideal for use with argon-methane mixtures (i.e. P-5 or
P-10 mixtures), commonly used with gas chromatographs utilizing SG6160 Oxygen Trap
electron capture detectors.
These traps incorporate a highly reactive, metal reagent, which is MC-1 Optional Mounting Clip
supported on an inert substrate, coupled with molecular sieves.
Oxygen is removed by chemical reaction with the reagent to form a
metal oxide. Oxygen levels can be effectively reduced to less than
5 ppb when starting levels are 10 ppm or less.
Service life of these traps will vary depending on the incoming Oxygen SG6162 Oxygen Trap
level in the carrier gas. However, it is estimated that when the starting
Oxygen level is <10 ppm, the Model SG6160 can purify four cylinders
(1200 ft3) of carrier gas, while the Model SG6162 can typically purify Specifications

adsorbed or completely excluded. This sieve-like selectivity, based
on molecular size, plus a selectable preference for polar or polor-
izable molecules, gives molecular sieves an extremely high level of
adsorption efficiency, and permits close tailoring of the adsorbent
to the specific use. Pore sizes vary by the type of molecular sieve;
for example, Type 4A has a uniform pore size of 4 angstroms. Mole-
cular sieves are available in a variety of forms which include powder,
pellets, mesh and beads:
Powders are white finely divided free-flowing particles with an
average diameter of 4-5 microns.

Vapor Shippers

MVE’s Vapor Shipper containers are designed for the safe transpor-
tation of biological samples at cryogenic (-150 oC) temperatures.
Fabricated from durable, lightweight aluminum, they contain a hydro-
phobic absorbent that contains the liquid nitrogen. The absorbent
also repels moisture and humidity, assuring the maximum holding
time. A protective shipping carton is available for all models (except
the SC 20/12 V) which protects the container from being placed on
its side and helps in withstanding the rigors of transportation. These
containers can be used to ship your samples with a “non-hazardous”
classification throughout the world, thus reducing costs and helping
to assure sample viability.

Liquid Level Controller

Praxair Replacement Liquid Level Controller

The Praxair Replacement Liquid Level Controller provides accurate control of liquid nitrogen
levels in cryogenic refrigerators. This unit can be substituted as a drop in replacement for
older controls in existing refrigerators. All system components are built to fit in all sizes of
cryogenic refrigerators.
The controller utilizes time proven thermistor based level sensing technology. The level of
the liquid nitrogen is maintained between the 2nd and 3rd sensor pods. The first sensor pod
provides a Low Level Alarm and the 4th sensor pod provides a High Level Alarm. The control
continuously monitors the status of the system including liquid level, temperature, system
events, and alarms. All information is displayed on a 2-line liquid crystal display. All data on
temperature, system events, and alarms is sent to the RS-232 serial port and is also recorded
in battery backed memory on the controller. The controller provides audible, visual and remote
alarm relay for all alarms.

Automated Liquid Nitrogen Supply Tank Switcher

The new MVE® Tank Switch enables two liquid nitrogen supply tanks to be connected to
one or more cryogenic freezers. When the primary supply cylinder is exhausted, the switch
automatically selects liquid delivery from the auxiliary cylinder and warns the user that the
primary cylinder requires replacement.
This unattended switching ensures that supply integrity is maintained to the storage system.
A visual alarm shows when the primary tank has been switched. Audible and visual alarms
indicate to laboratory personnel when both tanks are empty.
The tank switch operates by monitoring pressure in the transfer line, indicating both the
demand for and supply of liquid cryogen. This method eliminates the necessity for hard-
wired electrical connections to the cryogenic freezer control system avoiding the potential
for electrical interference within the freezer control system. This method of operation also
ensures a simple installation. Although designed primarily for cryogenic freezers, the tank
switch can be utilized to supply any device using liquid nitrogen at low pressure and at a
rate similar to liquid nitrogen freezers.

Excess Flow Shut-off Valves

Diffusion-Resistant, Diaphragm Seal,

Excess Flow Shut-off Valves (FS Series)
FS Series Excess Flow Shut-Off Valves are designed to automatically shut-off the
delivery of gas in a line if the flow exceeds a preset limit. They are commonly used as a
safety device to protect a system from excess flow in the event of equipment failure or to
protect personnel and property in the event of a line rupture. The capability of operating
from 10 to 3500 psi allows them to be used either in high or low pressure applications.
The Excess Flow Limit Valve is a 2-position valve. In the “Open (Reset)” position, the
valve provides a direct passage from inlet to outlet. In the other position, “Auto Shut-Off”,
the valve is set to sense the flow and automatically shuts off the passage if the flow
exceeds a preset value (flow limit). The valve will stay shut-off until it has been reset.
Six flow ranges are offered and the actual flow shut-off value for each range is depen- FS Series
dent upon the operating pressure. The graph below indicates, for each range, the re- Valve

1-877-PRAXAIR
lationship between operating pressure and the actual flow limit. It is suggested that the
range selected provide shut-off at 2-6 times the anticipated flow rate to allow for short
term flow surges not connected with equipment failure.
Note: Piping systems, cylinders and other equipment can contribute rust or other par-
ticulate contamination that could cause the device to fail. Therefore it is highly recom-
mended that all gases be filtered before they enter the FS Series Valve. See Optional
Equipment for additional information .

Check Valves (CV5600 Series)

Check valves ensure that gases or liquids flow in one direction only.
When used on the outlet line of pressure regulators, they prevent
back flow of fluids into the regulator. When used in cylinder pigtails,
they prevent gas flow from one cylinder into another on the same
manifold. They also stop air from entering the pigtail and manifold
when a cylinder is removed.
These check valves are bubble-tight against any back pressure.

Cylinder Connections

Cylinder connections are used for connecting various items of gas handling apparatus
(such as pressure regulators or pigtails) directly to high pressure gas cylinders. The
actual connection varies depending on the gas in the cylinder and is designated by a
three digit code (CGA Connection Number) as set forth in Compressed Gas Association
publication V-1. Cylinder connections consist of a CGA nut and CGA nipple and in some
cases require a washer for sealing purposes.
Praxair offers cylinder connections in a variety of configurations and materials. One
configuration, available in either brass or type 316 stainless steel, features a check valve
housed within the CGA nipple. This configuration restricts flow to only one direction, and
prevents “backflow” from the process to the cylinder.
Also offered are special type 316L stainless steel cylinder connections which end
in a male vacuum-type face seal fitting for use in systems utilizing VCR® or VCR®
compatible type fittings.

Portable Headspace Analyzer

Food Applications
The 901 Series portable headspace analyzer has proven itself in hundreds of installations for food applications
such as meats, fresh produce, pasta, nuts, snack-foods, dairy products and coffee. The sensor is unaffected
by high levels of background gases such as nitrogen or carbon dioxide. The 901 Series can also be used for
applications where the oxygen level is very high (50 to 100%), without overloading the sensor. It is unaffected
by trace hydrocarbons or high levels of CO 2, which can poison other types of sensors. The 901 Series is a
battery-operated, portable oxygen analyzer used for the measurement of residual oxygen in gas-flushed
(CAP/MAP) food packages. This hand-held unit can be used by non-technical personnel where you need it,
in the lab or at the packaging line, or it can be easily transported to other locations. The 901 Series is powered
by Ni-Cad re-chargeable batteries, which provide 8 hours of operation before recharging is required.
Easy Sampling Analysis
The 901 Series portable headspace analyzer sample probe is tipped with a particulate filter and luer fit syringe
needle with side-port holes to prevent plugging. The sample is drawn through the probe and tubing and then to
the oxygen sensor when the pump is turned on. The pump is electronically timed to draw in the precise amount
of sample required for the analysis, and then turns itself off after the pre-set sampling time (5 to 10 seconds).
The oxygen concentration is read on the display. It is a cost effective, reliable alternative to other analyzers. Not
www.praxair.com/specialtygases

only is the initial cost much lower, but operating and maintenance costs are lower as well. When service is
required, units are generally repaired and returned the same day as received to minimize down-time.
Principle of Operation
The 901 Series uses a syringe needle sampling assembly to pierce the package and draw a sample into the
analyzer sensor for oxygen measurement. The sensor signal is converted to percent concentration and displayed
on the LCD screen. The oxygen sensor used in the 901 Series was specifically designed for gas-flushed pack-
aging measurements. The sensor is a proprietary electrochemical design which is inexpensive, quick to respond,
requires minimal power and has excellent zero and span stability. Unlike zirconia sensors which are heated to
500-600 oC, the 901 analyzer will not crack when exposed to liquid water droplets and is unaffected by trace
hydrocarbon gases.

Oxygen/Carbon Dioxide Analyzer

The headspace analyzer is used for the analysis of oxygen, carbon dioxide, and combination O2/CO2 headspace
in flexible or rigid packages. It incorporates a new technology which alerts the operator in the event of a blockage
of gas flow from the package to the analyzer. The headspace analyzers are used in production, quality control,
and R & D applications to assess package integrity. This instrument is certified traceable to NIST.

Single Point Gas Detection Monitor

Draeger® PointGard® ll Single Point Gas Detection Monitor

The Draeger® PointGard® ll is a microprocessor-based stand-alone gas detector for continu-
ous monitoring of toxic gases and oxygen in ambient air. Gas concentration is displayed using
bright LEDs, while the horn and two strobes provide alarm annunciation where it is needed
most: at the point of the hazard.
The heart of the Draeger® PointGard® ll is the electrochemical DrägerSensor®, the latest
development in gas sensing technology. The DrägerSensor® is designed for accuracy,
stability, and long life. Temperature compensation has been optimized and cross sensitivity
to other gases minimized, ensuring an accurate reading of the target gas concentration.
Installation is easy: just mount the unit on a wall, install the sensor, and plug the line cord into
a 110 or 220 VAC outlet. Sensors are pre-calibrated before shipment, so calibration is not
necessary at start-up. The simple menu guided user interface can be accessed through
3 buttons on the front panel of the instrument.

SNAP CAP
Designed to fit most North American high and low pressure gas cylinders, the SNAP CAP
cylinder safety device meets DOT standards. The SNAP CAP denies access to the main
cylinder control and regulator attachment, rendering the cylinder, it’s contents, and your
regulator useless to anyone but your designated personnel. At less than the cost of a cylinder
refill and much less than a regulator, the value is obvious. Welded steel construction and
powder coated provides many years of use.

Tube Style Cylinder Racks

Tube style racks are recommended where cylinders may be exposed to vehicular traffic or
material handling equipment collisions. These racks fully surround cylinders with 2 inch square
steel heavy gauge (.125" wall) tubes welded and sealed with epoxy powder paint. Two levels
of welded steel chains with snaps on each end make cylinder racking easy and convenient.
All feature fully welded arms and backs, and quickly bolt together, saving half the freight cost
over fully assembled units. We will ship units fully assembled on request. All racks are
available in standard and custom configurations from one to 16 or more cylinder capacity.
Process station versions available. All listed units meet or exceed requirements for UFC,
NFPA, CGA, and OSHA, as well as Seismic Zone 4 requirements.
