Abstract
Analytical chemistry is very important for the development of any new drug in market. Every chemist used various methods and instruments for the data interpretation of particular drugs in following article. We will discuss various instruments, their relative principals, methods and instrumentation part along with their pharmaceutical and non pharmaceutical application. The following article describes spectroscopic instrument i.e. Ultraviolet spectroscopy (UV), the recent and most usable instruments i.e. HPLC and HPTLC. These are sophisticated instrumental technique based on the full capabilities of thin layer chromatography. The advantages of automation, scanning, full optimization, selective detection principle, minimum sample preparation, hyphenation, better interpretation etc. enable it to be a powerful analytical tool for chromatographic information of complex mixtures of inorganic, organic, and bio molecules.
