After a 25-year dormant period, chromatography was finally reborn in the first years of the 1930s.

The volatile extraction market consists of three techniques: purge and trap, headspace, and thermal desorption equipment. These systems are often employed as a sampling method for gas chromatography (GC) instrumentation but are also used with IR detectors, electrochemical sensors of electronic noses, and mass spectrometers.

This article describes the use of ultrahigh-pressure liquid chromatography (UHPLC) in pharmaceutical analysis of drug substances and drug products with UV absorption detection.

Getting started on the right foot is important for efficient method development.
