**7. Analytical techniques for method development and validation**

The various analytical techniques are available for Qualitative and Quantitative analysis, which can be used in above explained types of analytical methods. The chromatographic techniques used as a separation tool and spectroscopic techniques are used for an identification and to obtain structural information. Among all these techniques High performance liquid chromatography, High performance thin layer chromatography, Spectrophotometric techniques and Hyphenated techniques are explained in brief.
