Gas chromatography mass spectrometry (GCMS) is one of the most common methods of analysis for a wide range of compounds including volatile (VO), semi-volatile (SVO) and nonpolar organics. Spex® GCMS standards are widely available for analyses ranging from agricultural testing to environmental samples for semivolatiles and volatiles.
