Multi-gas monitoring with GASERA ONE PULSE

GASERA ONE PULSE is a versatile and easy to use multi-gas monitoring solution. It offers accurate ppb detection at an unbeatable price. It can be configured for a range of uses and is currently in use by our customers in; detecting SF6 leakage, refrigerant leakage, anesthetic gas monitoring, emissions monitoring of greenhouse gases, soil analysis, occupational health and safety, photocatalysis, animal husbandry, and fume hood performance testing.

Detection Limits and Selectivity

Gasera’s patented cantilever enhanced photoacoustic technology delivers ppb gas detection in the most challenging measurement environments and at an industry leading price.

This is achieved by the GASERA ONE PULSE’s unique measurement capabilities and advanced chemometric algorithms that use up to ten different measurement signals to ensure that your target gases can be swiftly and accurately measured even in the presence of the most troublesome interferents, such as high levels of moisture where competitor systems cannot tolerate.

Scienze can work with you to configure the GASERA ONE PULSE to achieve the detection performance required for your application. Call us now freephone 0800 724 633

Configuration Options

Several option possibilities enable even more versatile use of the multi-purpose GASERA ONE PULSE instrument.

Multipoint Sampling

GASERA ONE PULSE can be combined with our multi-channel sampling system to deliver even more gas monitoring capabilities and value.

The multi-channel sampler enables an automated and programmable sampling sequence of up to 12 different gas measurement sampling points to each GASERA ONE PULSE instrument, providing a cost-effective solution for customers.

Different applications require a different set of target gases. This is achieved with the selection of an appropriate set of optical filters for each unit. Some applications require field use. For this, a portable enclosure option is available with battery-powered operation.

Portable Field Use

Gasera’s unique technology enables miniaturisation of our instrument with no reduction in measuring sensitivity. It is also robust, and a low power technology compared to power hungry, fragile FT-IR spectrometers and GC-MS instruments. This allows Gasera to offer a battery powered portable product to enable gas detection in the most difficult locations. It is our “four-wheel drive” version that still offers ppb detection and ease of use, but now our customers can measure anywhere. With enhanced features to combat the range of temperatures and vibration that a field instrument may experience, our portable instrument is also designed for ease of transport with a roll on hard-case shell.

Measurable Gases

Anesthetics: desflurane, enflurane, isoflurane, sevoflurane etc.
Greenhouse gases: CF4, C2F6, R13, R-134a, CO2, N2O etc.
Tracer gases: SF6, R-134a, HFO-1234yf
Hydrocarbons: CH4, C2H2, C2H4, C2H6 etc.
Inorganics: CO, CO2, H2O, NO, NO2, N2O, NF3, NH3, SF6, SO2
VOCs: acetone, benzene, ethanol, formaldehyde, methanol, toluene, xylenes etc.

Specifications

Response time: dependent on user configurable channel integration (C.I.T.) and gas exchange routine. Typically from 5 seconds to a few minutes (model dependent)
Detection limit: gas and light source dependent. Typically from sub-ppb to sub-ppm
Dynamic range: typically 5 orders of magnitude (i.e. 100 000 times the detection limit)
Repeatability: less than 1% of measured value in operational conditions at the calibration concentration
Accuracy: limited by the calibration gas accuracy at the calibration concentration. Typically 2-5%
Temperature stability: ambient temperature change within the operational temperature range will not cause drift
Pressure stability: sample gas pressure change within the pressure range will not cause drift

GASERA ONE PULSE Table for Detection Limits

GASERA ONE PULSE is a flexible multi-gas analyzer that can be configured to cover numerous gas monitoring applications. Our customers are using it, for example, in greenhouse gases monitoring, photocatalytic materials research, switchgear tightness testing, and occupational health and safety monitoring.

We have now covered the most typical gases that can be monitored with GASERA ONE PULSE in one table along with technical information. Up to 10 gases can be selected to be monitored simultaneously. We have also updated our product presentation to include all the features, specifications, and typical applications in one presentation.

New Review Article featuring GASERA ONE FORMALDEHYDE published

GASERA ONE FORMALDEHYDE gas analyzer has been included in the recent review article "Analytical chemistry of carbonyl compounds in indoor air", by Prof. Tunga Salthammer of Fraunhofer WKI, published in the Analyst issue 15.

Prof. Salthammer found the technology established, performance suitable for monitoring formaldehyde in indoor air, and the device practical for the purpose. In a demonstration in the article, measurements carried out with GASERA ONE FORMALDEHYDE show a superior time resolution and a nearly perfect correlation when compared to the current reference method DNPH (see the figure).
