Application Note: Blood Alcohol Content Analysis using Nitrogen Carrier Gas
12 August 2015

Alcohol consumption can seriously affect the ability of a driver to operate a vehicle and blood alcohol content (BAC) directly correlates with this impairment. Usually, blood alcohol content is analyzed using helium as a carrier gas but with shortages and increases in cost, alternative gases are being employed. In this application note, nitrogen is used as a carrier gas for headspace GC with FID detection.
