  Biopharmaceutical analysis deals with the qualitative identification/confirmation and quantitative measurement of drugs or drug metabolites in biological fluids. The biological fluids include whole blood, plasma, serum, saliva, cerebrospinal fluid, urine etc. The qualitative identification/confirmation determines the organoleptic and physicochemical characteristics whereas quantitative analysis could be for bioequivalence, pharmacodynamics, pharmacokinetics, toxicokinetics purposes. Biopharmaceutical analysis also applies to drugs used for illicit purposes, forensic investigations, anti-doping testing in sports. This analytical technique unlike chemical analytical technique could face challenges arising from components of the sample matrix interfering with the analyte(s) of interest. Because these drugs/metabolites are in these complex and varied matrices, detection limits vary depending on the drug/metabolite. As the drugs/metabolites very often occur at very low concentrations (trace or ultra trace levels), sensitive and selective methods that are easily automated and within minimum pretreatment are preferable.
