Essay On Pharmaceutical Analysis

Pharmaceutical Analysis play a important role todays, and it can be considered as interdisciplinary subject. Pharmaceutical analysis derives its principles from various branches of science like Chemistry, Physics, Microbiology, Nuclear Science, Electronics, etc. pharmaceutical analysis mainly in two areas it is quantitative analysis and qualitative analysis. A qualitative method is the information about the identity of atomic or molecular species or functional groups in the sample. A quantitative method provides numerical information as to the relative amount of one or more of these components. now a days Analytical instrumentation plays an important role in the production and evaluation of new products. The instrumental

E.g. Potentiometer, Conductometry ,Polarography, Amperometry, Paper Electrophoresis.
Physical Methods We measure some physical characteristics of drug.
E.g. Differential Thermal Analysis, Differential Scaning calorimetry,Therom mechanical Analysis, Thermo Gravimetric Analysis.
Titrimeteric Methods Non-aqueous titration , redox titrations, diazotization titration and complexometric titration.
What is chromotography A Russian botanist, Mikhail Tswett (1872 - 1919), is credited with the first use of chromatography in 1906 when he separated plant pigments such as chlorophylls and xanthophylls. He passed them through a glass column packed with calcium carbonate. These pigments are coloured and thus the technique was named using the Greek terms, ‘chroma’ meaning ‘colour’, and ‘graphein’ meaning ‘to write’. This explains why the name seemingly bears little relation to the use of the technique today.

Chromatography is a technique which separates components in a mixture due to the differing time taken for each component to travel through a stationary phase when carried through it by a mobile phase. The possible mixtures of phases give rise to the types of chromatography listed in Table
