Quality Control is that part of GMP, which is concerned with sampling, specification and
testing, and with the organization, documentation and release procedures, which ensure that
the necessary and relevant tests are, in fact, carried out, and that materials are not released for
use, nor products released for sale or supply, until their quality has been judged to be
satisfactory.
It involved the examination of a raw material, process product, for certain minimum levels of
quality. The goal of a quality control team was to identify products that do not meet a
companys specified standards of quality. If a problem was identified, the job of a quality
control team or professional may involve stopping production temporarily.
Quality control department is backbone of the industry. It not only gives assurance of
required quality in given product through various analytical techniques but also faces audits
conducted by customers, so a strong quality control department indicates higher quality in its
product.
Sampling procedures depends on the nature of the raw material, in process or finished
product lots, conveying and sampling equipment. Prior knowledge of the product data and
sampling resources allows the assignment of the appropriate sampling procedures. The use of
recognized international sampling methods ensures a standardized administrative and
technical approach and facilitates the interpretation of results of analysis related to lots.
Colour code system:Red label: Raw material is rejected
Yellow label: Raw Material under test
Green label: Raw material is approved
Sampling is done in a well defined area in order to avoid difficulties in the executing of
procedures, reduce the risk of contamination and cross contamination, enable the proper
execution of laboratory analysis and include all necessary safety and health precautions to the
sampler and environment.
For the execution of the sampling procedures proper tools and materials are available.
Personnel responsible for the sampling activities are trained on the applicable procedures. All
tools and auxiliary materials are inert, and in a clean condition before and after their use.
Rule of sampling - when there are more than 5 containers of raw material, the number of
container sampled is determined by following formula
Quantity of sample to be sampled There are number of factor which determine the amount
of sample to be sampled. They are amount required for analysis, cost of material.
Samplings of solid Solid samples are sampled by using bigger size spatula or sampling
cork.
Sampling of Liquid-Liquid samples is sampled by using sampling rod.
Before going for sampling analyst sees GRN slip given by warehouse to see what to be
sampled & accordingly labels of Under Test, labels of sampled by should be prepared. The
sampling form is filled during sampling. Once the sampling is done analyst sticks under test
label to all the containers. Once sample is analyzed and approved then approved label is put
on. If sample is analyzed and fails to pass all the tests given in its SOP of analysis then the
rejected label is put on the container.
INSTRUMENTS OBSERVED
Colorimetric titration
The main compartment of the titration cell contains the anode solution plus the analyte. The
anode solution consists of an alcohol (ROH), a base (RN), SO2 and I2. A typical alcohol that
may be used is methanol or diethylene glycol monoethyl ether, and a common base is
imidazole.
The titration cell also consists of a smaller compartment with a cathode immersed in the
anode solution of the main compartment. The two compartments are separated by an ionpermeable membrane.
The Pt anode generates I2 when current is provided through the electric circuit. The net
reaction as shown below is oxidation of SO2 by I2. One mole of I2 is consumed for each mole
of H2O. In other words, 2 moles of electrons are consumed per mole of water.
CH3OH + SO2 + RN [RNH] SO3CH3
H2O + I2 + [RNH] SO3CH3 + 2RN [RNH] SO4CH3 + 2 [RNH] I
(RN = Base)
The end point is detected most commonly by a bipotentiometric method. A second pair of Pt
electrodes is immersed in the anode solution. The detector circuit maintains a constant current
between the two detector electrodes during titration. Prior to the equivalence point, the
solution contains I but little I2. At the equivalence point, excess I2 appears and an abrupt
voltage drop marks the end point. The amount of current needed to generate I2 and reach the
end point can then be used to calculate the amount of water in the original sample.
Volumetric titration
The volumetric titration is based on the same principles as the coulometric titration except
that the anode solution above now is used as the titrant solution. The titrant consists of an
alcohol (ROH), base (B), SO2 and a known concentration of I2.
One mole of I2 is consumed for each mole of H 2O. The titration reaction proceeds as above
and the end point may be detected by a bipotentiometric method as described above.

Advantage of analysis
The popularity of the Karl Fischer titration is due to several practical advantages that it holds
over other methods of moisture determination, including:
1
High accuracy and precision

Liquids

Gases

Independence of presence of other volatile compounds
12
In contrast, loss on drying will detect the loss of any volatile substance.
The major disadvantage is that the water has to be accessible and easily brought into
methanol solution. Many common substances, especially foods such as chocolate, release
water slowly and with difficulty, and require additional efforts to reliably bring the total water
content into contact with the Karl Fischer reagents.
2. pH METER
A pH meter is a handheld device that tests water for its level of acidity versus base
or alkalinity. If water is equally acidic and alkaline, it registers as neutral on a pH
meter. The pH meter utilizes a standard pH scale for
measuring these aspects of
water quality. The level of concentration of positive hydrogen ions in the water
determines the result. The acidic side of the pH scale runs from 0 to 6.9, with 7.0
being neutral. Because 7.0 is neutral, 6.8 is considered only slightly acidic. Similarly,
7.2 is only slightly alkaline, with the base scale running to 10.0 or higher. Generally
speaking, acidic water is soft while alkaline
or base water is hard.
9
PRINCIPLE:
A pH meter measures essentially the electro-chemical potential
between a known
liquid inside the glass electrode (membrane) and an unknown liquid outside. Because
the thin glass bulb allows mainly the agile and small hydrogen ions to interact with
the glass, the glass electrode measures the electro-chemical potential of hydrogen ions
or the potential of hydrogen. To complete the electrical circuit, also a reference
electrode is needed. Note that the instrument does not measure a current but only an electrical
voltage, yet a small leakage of ions from the reference electrode is needed, forming a
conducting bridge to the glass electrode. A pH meter must thus not be used in moving liquids
of low conductivity (thus measuring inside small containers is preferable).
The calomel reference electrode consists of a glass tube with a potassium chloride (KCl)
electrolyte which is in intimate contact with a mercuric chloride element at the end of a KCL
element. It is a fragile construction, joined by a liquid junction tip made up of porous ceramic
or similar material. This kind of electrode is not easily poisoned by heavy metals and
sodium.
The glass electrode consists of a sturdy glass tube with a thin glass bulb welded to
it. Inside is a known solution of potassium chloride (KCl) buffered at a pH of 7.0. A
silver electrode with a silver chloride tip makes contact with the inside solution. To minimise
electronic interference, the probe is shielded by a foil shield, often found inside the glass
electrode.
Calibration of pH METER:
For normal use calibration should be performed at the
reason for this is that the glass electrode does not give
longer period of time.
PROCEDURE:
1
2
3
Switch on pH METER.
Allow the pH METER to attend temperature around 21C.
The glass electrode is rinsed with distilled water and wiped with clean tissue
paper.
4
Use standard solution of buffer 4.00, 7.00, 9.20 respectively.
Immersed the glass electrode in standard buffer solution with intermittent
washing with distilled water.

Keep the record of reading into the log book of pH METER
Note :- Glass electrode tip must be kept wet at all times.

TAILA
Taila are preparations in which taila is boiled with prescribed kasayas (Decoction) & kalkas
of drugs according to the formula this process ensure absorption of the active therapeutic
properties of the ingredient used.
General method of preparation:
There are generally three essential for preparation of sneha(gharta or taila)
Drava (a liquid which may be one more as kasaya, svarasa, dugdha, mastu .etc)
Kalka (a fine paste of the drugs)
Sneha, Dravyas (taila, murcchita taila etc.)
Generally unless otherwise mentioned in the text if kalka is the one part by weight Sneha,
should be four parts and Drava- Dravya should be sixteen parts exceptions are,

ksira, takra, dadhi the kalka should be one-eighth of the sneha and
four times
water
is addedisfor
good Paka.
Where
the number Dravyas is four or less than four, each dravya has to be taken four times the weight
of sneha.
Where the Drava Dravyas are five or more, each dravya will be equal in weight to
the sneha.
If in a preparation, no kalka dravya is prescribed, then the drugs of the kasaya may be used as
kalka.
The kalka are the dravya are mixed together, sneha is added to the boiled and mild fire and
stirred well continuously so that the kalka is not allowed to adhere to the vessel. Sometimes
the Drava- Dravyas are direct to be added one after another as the process of boiling is
continued till the Drava-Dravyas added earlier has evaporated.
When all the Drava-Dravaya has evaporated the moisture in the kalka will also begin to
evaporate at this stage, it has to be stirred more often and the carefully to ensure that the
kalka does not stick to the bottom of the vessel. The kalka is taken out of the ladle and tested
from time to now the condition and stage of the Paka.

Madhyam Paka
Khara Paka
In mrudu paka, kalka is waxy and when rolled between fingers rolls like lac without sticking.
In Madhyam Paka, kalka is harder and when put in fire burns without any cracking noise a
further degree of heating lead to khara Paka. Any further heating will lead to dagdha paka and
the sneha becomes unfit for use when the taila attains the correct paka stage froth comes out.
In the sneha group savkara, if mentioned is added in fine powder form to the final product
when cool.
Where the Parka is to be done with kwacha, svarasa, dugdha & mamsarasa, etc. the Paka is to
be done
with the dravas separately in the above order. The period of paka with various

CHRACTERISTICS of Taila:
Taila will generally have the color, odor, & tastes of drugs used & have the consistency of the
oil. When considerable quantity of milk is used in the preparation; the oil becomes thick due
to Ghrita & in cold season may condense further.
PRESERVATION:
Taila are preserved in the glass, polythene or aluminium containers. Preparations for internal
use help their potency for about sixteen months.
METHOD OF USE:
Tailas are generally used for abhyanga, some of them are also used externally & in ayurvedic
texts various types of anupanas are described for this purpose. When no such anupana is
mentioned it should be taken with warm water or warm milk

TESTING METHOD
Iodine is tested as per USP 36 .The given sample should comply with the given standards.
Iodine contains NLT 99.8 % and NMT 100.5 % of I.
STANDARDS
Description: Greyish violet brittle plates or small crystals with a metallic sheen; odour,
irritant. It volatalises slowly at room temperature.
Solubility: Soluble in chloroform, in ethanol (95%); slightly soluble in glycerin; very slightly
soluble in water. very soluble in concentrated solution of iodides.
Identification: (A) Solution (1 in 1000) in chloroform and in carbon disulfide has a violet
colour.
(B) To a saturated solution add starch-potassium iodide TS: a blue colour is produced. When
the mixture is boiled, the colour vanished but reappears as the mixture cools, unless it has
been subjected to prolonged boiling.
Non-volatile residue: Place 5.0 g in a tared porcelain dish, heat on a stem bath until the
iodine has been driven off, and dry at 105
0
for 1 hour: not more than 0.05 % of residue remains.
Chloride or bromide: Triturate 250 mg of finely powdered Iodine with 10 ml of water, and
filter the solution. Add drop wise, sulphurous acid (free from chloride), previously diluted
with several volumes of water, until the iodine colour just disappears. Add 5 ml of 6 N
ammonium hydroxide, followed by 5 ml of silver nitrate TS in small portions. Filter, and
26
acidify the filtrate with nitric acid: the resulting liquid is not more turbid than a control made
with the same quantities of the same reagents to which 0.10 ml of 0.020 N hydrochloric acid
has been added, the sulphurous acid being omitted (0.028 % as chloride).
Assay: Place about 500 mg of powdered Iodine in a tared, glass-stoppered flask, insert the
stopper, weigh accurately, and add 1 g of potassium iodide dissolved in 5 ml of water. Dilute
with water to about 50 ml, add 1 ml of 3 N hydrochloric acid, and titrated with 0.1 N sodium
thiosulfate VS, adding 3 ml of starch TS as the end-point is approached. Each ml of 0.1 N
sodium thiosulfate is equivalent to 12.69 mg of I.

WEIGHT PER ML
The weight per millilitre (weight per ml) of a liquid is the weight in g of 1 ml of
liquid when weighed in air at 20C, unless otherwise specified in the monograph.
The weight per millilitre is determined by dividing the weight in air, expressed in g,
of the quantity of liquid that fills a pycnometer at the specified temperature by the
capacity, expressed in ml, of the pycnometer at the same temperature. The capacity
of the pycnometer is ascertained from the
weight in air, expressed in g, of the
quantity of water required to fill the pycnometer at that temperature. The weight of a litre of
water at specified temperatures when weighed against brass weights in air of
density 0.0012 g per ml
is given in the following table. Ordinary deviations in the
density of air from the above value, here taken as the mean, do not affect the result
of a determination in the significant
figures prescribed for Pharmacopoeial substances.

LOSS ON IGNITION
Muffle Furnace
The Loss on Ignition test is a method to measure the loss in mass when the sample is ignited
under the condition specified in each monograph. This method is usually applied to inorganic
drugs which lose a part of the components or impurities during ignition.
PROCEDURE:
1 Heat a silica or platinum crucible to redness for 10 minutes, allow to cool in a
Desiccator and weigh.
2 Transfer to the crucible 1g of substance under examination and weigh the crucible and
the content accurately.
3 Ignite gently at first until the substance is thoroughly charred.
Cool moisten the residue with 1ml of concentrated H2SO4 heat gently until the
white fumes are no longer evolved and ignite at 800C 25C until all black

Saponification value gives an indication of nature of fatty acids in the fat since longer carbon
chain; the lesser is the amount of acid liberated per gram of fat hydrolyzed. When fat or oil is
heated with an alcoholic solution of KOH, free fatty acids & glycerol are liberated. The
refluxing with glycerol esters yields glycerol & K-salt of fatty acids. Subsequently the test
sample as well as control is titrated against HCL to determine the amount of KOH used in the
saponification process.
Procedure:
1) Introduce about 2 gm of the substance to be examined accurately weighed into a 200
ml flask of borosilicated glass fitted with a reflux condenser.
2) Add 25 ml of 0.5 N alcoholic potassium hydroxide, accurately measured.
3) Boil under reflux on a water bath for 30 minutes, frequently rotating the content.
4) Add 1 ml of phenolphthalein solution & immediately titrate with 0.5 N HCL.
5) Note the volume in ml of titrant (a)
Blank: Carry out a blank test under the same condition, omitting the substance. Note the
volume in ml of titrant (b)
Calculation:
Saponification value = (b-a) x 28.05

The standard plate count is usually done by diluting the original sample, plotting
aliquots of the dilutions onto an appropriate culture medium, and then incubating the
plates under proper conditions so that colonies are formed.
2
After incubation, the colonies are counted and from knowledge of dilution used, the
original number of viable cells can be calculated. The total viable cells are usually
reported as colony forming units (CFUs).
3
This method of plate count is relatively easy to perform and is much more sensitive
then turbidimetric measurements. A measure disadvantage is that, the time necessary for
dilutions, plotting and incubations as well as the time needed for media preparations.

In Formulation 3 growth was observed on Nutrient agar plate in dilutions 1:10 and 1:20 & the CFU/ml
calculated was 7200 and 600 respectively.
Since growth was observed in Nutrient agar plate and Sabourauds agar plate, it is of fungal
and yeast contamination.
Conclusion:
Total Viable count is an effective and widely used technique for assessing the microbial
count. All the three formulations showed growth due to microbial contamination which
further indicates that the formulations are of inferior quality.
