4.1 SELECTION OF ANALYTICAL PERFORMANCE PARAMETERS
As per cGMP guidelines the test methods, which are used for assessing the quality of pharmaceutical products with established specifications, must be validated for analytical performance parameters viz; Limit ofdetection,Limit of quantitation, Precision, Accuracy, Linearity & range and Ruggedness.
However, if the analytical method employed is in the IP, BP., USP /NF, Association of official analytical chemists, Book of methods or inother recognized standard references, or is detailed in an Approved NewDrug Application (ANDA) and the preferred method is not modified, isnot required to be validated for accuracy and reliability parameters butmerely verify their suitability under actual conditions of use.i.e. For itssuitability under actual conditions of use,(Placebo interference),Precision, Accuracy, Linearity & Range, Ruggedness.
Listed below in Table 1 are analytical parameters required to bevalidated depending upon the test and pharmacopoeial status.

Analytical method validation study forChloramphenicol” content in Chloramphenicol 250 Capsuleshall be carried out forthe following analytical performanceparameters viz, accuracy, precision, specificity, linearity, range, andRuggedness study.
5.2 DESCRIPTION OF ANALYTICAL METHOD
The detailed analytical method for the determination of Chloramphenicol” content in 250 Capsuleis described below:
* UV Spectrophotometer (Make:- )
* Analytical balance (Make: – )
*Volumetric flask 200 ml,100ml.
*Volumetric Pipette 10 ml
* Glass Beaker
* Glass Funnel
Weigh accurately a quantity of the mixed contents of 20 capsules equivalent to about 0.2 g of Chloramphenicol, dissolve in 800 ml of water, warming if necessary to effect solution and add sufficient water to produce 1000.0 ml. Dilute 10.0 ml of this solution to 100.0 ml with water and measure the absorbance of the resulting solution at the maximum at about 278 nm, . Calculate the content of C11H12Cl2N2O5, taking 297 as the value of A (1%, 1 cm) at the maximum about 278 nm.
Limits : not less than 92.5% w/w and not more than 107.5% w/w of the stated amount of Chloramphenicol C11H12Cl2N2O5.

6.0 DESCRIPTION OF ANALYTICAL PERFORMANCE PARAMETERS
6.1 SPECIFICITY STUDY(PLACEBOINTEREFERENCE)
Specificity of an analytical method is its ability to measure accuratelyand specificallythe analyze in the presence of components viz. knownand unknown impurities, degradation products or placebo ingredients thatmay be expected to be present in the sample matrix.
Placebo study of analytical method use for drug product is checkingthe positive or negative interference due to placebo on final resultsof analytical method. Placebo study of the Chloramphenicol” content in CAFCOL 250 Capsule shall be established by analyzing the placebo as perassay method and calculating the % interference of the same.
6.2 ACCURACY STUDY
The accuracy of an analytical method is the closeness of test results obtained by that method to the true value. Accuracy may often be expressed as percent recovery by the assay of known, added amount of Chloramphenicol.
The accuracy of the method is determined by adding known amount of Chloramphenicol to cover both, above and below (80%, 100% & 120%) the normal level of the analyte concentration.
The accuracy of the assay method of Chloramphenicol” content in Chloramphenicol 250 Capsule shall be determined by adding known amount of Chloramphenicolin placebo to cover both above and below ( 80% , 100% & 120% ) the normal levels
(label claim)expected in the samples.
6.3 PRECISION STUDY (Repeatability)
The precision of an analytical method is the degree of repeatability of the results in a series of experiments run during a single session by single operator with identical reagents andequipments.
Precision of the Chloramphenicol” content in Chloramphenicol 250 Capsule shall be stablishedby separately weighing and analyzing the samples from a homogeneous sample for six times and by calculating % RSD.
The precision of the analytical method is established by performing two types of precision study.i. e. System precision study& Intermediate precision study.
6.3.1 SYSTEM PRECISION STUDY (REPEATABILITY)
This study is to confirm the degree of repeatability of the results in a series of experiments during a single session by single operator with identical reagents, glassware’s and equipment’s. Hence the reliability of standard analyte, reagents as well as equipment is evaluated by this study.
6.3.2 INTERMEDIATE PRECISION STUDY (REPRODUCIBILITY) / RUGGEDNESS
This study is to confirm the degree of repeatability of the results in a series of experiments within the same laboratory but different days, analysts, equipment’s/reagents.
6.4 LINEARITY &RANGE STUDY
The linearity of an analytical method is its ability to elicit test results directly proportional to the concentration of the analyte in samples within given range.
Linearity of Chloramphenicol” content in 250 Capsule shall be studied by taking minimum of five concentration of test sample in the range of drug substance from 40 % to 140 % content Linearity curve shall be plotted for absorbance against concentration. Correlation coefficient is calculated using above plot.
6.5STABILITY OF SOLUTION:
To demonstrate Stability of solution study, test solution of the Chloramphenicol” content in 250 Capsules shall be checked for stability of test solution over 24hrs and comprised the test results of sample containing impurities or degrading product
