The pharmaceutical analysis involves a series of protocols for the identification, quantification, purification, and characterization of drug substances. The pharmaceutical substances may be pure drug molecules, unfinished formulations or finished formulations, excipients etc. The analysis may be qualitative, to determine the composition of natural/synthetic substances, or quantitative and may alsoinvolve studies related to pharma kinetics.
There are numerous analytical techniques available for the analysis. Chemical methods involve titrimetric and volumetric methods, gravimetric methods and gasometric methods among others. Electric methods include the measurement of electric current, voltage or resistance in relation to the concentration of some compounds in the solution. Instrumental methods involve chromatography, electrophoresis, mass spectrometry, nuclear magnetic resonance spectroscopy and other techniques. Biological and microbiological methods involve various assays to determine the anti-microbial potency of the pharmaceuticals.
These pharmaceutical analysis procedures require various equipment and spare accessories. For characterization of drug formulations, equipment such as hardness tester, disintegration apparatus, tap density tester, tablet friability tester, etc. are required. Such products can be sourced from the manufacturers like LabIndia Analytical, on the Biomall platform.
