INTRODUCTION
Pharmaceutical analysis comprises the procedures necessary to
determine the identity, strength, quality and purity of substances
of therapeutic importance.
 Quality is important in every product or service, but it is vital in
medicines as it involves life.
 Analytical techniques that are generally used for drug analysis are
o Chromatographic methods,
o Spectral methods,
o Biological and Microbiological methods.

 Validation of Analytical Method
validation is the process used to confirm that the analytical
procedure employed for a specific test is suitable
for its intended use.
The various validation parameters are:
 Accuracy,
 Precision (Repeatability and Reproducibility),
 Linearity and Range,
 Limit of detection (LOD) / Limit of quantitation (LOQ),
 Selectivity / Specificity,
 Robustness / Ruggedness,
 Stability and System suitability studies

INSTRUMENTATION
 HPLC is one mode of chromatography,
 Chromatographic processes can be defined as separation techniques
involving mass-transfer between stationary and mobile phases.
 HPLC utilizes a liquid mobile phase to separate the components of a
mixture.
 These components (or analytes) are first dissolved in a solvent, and then
forced to flow through a chromatographic column under high pressure. In
the column, the mixture is resolved into its components.
 As a result, HPLC acquires a high degree of versatility not found in other
chromatographic systems and has the ability to easily separate a wide
variety of chemical mixtures.
