AGILENT HEADSPACE SAMPLER UPGRADE

The National Institute on Alcohol Abuse and Alcoholism (NIAAA) is seeking to upgrade their Agilent headspace sampler, a critical component of their gas chromatography/mass spectrometry (GC/MS) system. The GC/MS system is used to determine ethanol and its metabolites in biological samples. The headspace sampler hosts samples in its trays and systematically introduces them into the GC/MS instrument. The upgrade is necessary to reduce bias introduced by prolonged exposure of samples to room temperature. • The headspace sampler is used for determining ethanol and its metabolites in biological samples. • The GC/MS system processes samples one after another according to a pre-scheduled sequence. • A single sequence run involves 80 samples and requires approximately 20 hours to complete. • The upgrade is necessary to reduce bias introduced by prolonged exposure of samples to room temperature.
