Application Note: Detecting Barbiturates by Reversed Phase Liquid Chromatography
5 May 2010

Barbiturates are central nervous system depressants and they act in a similar manner to alcohol and slow down many areas of the brain. This application note presents a method of extracting barbiturates from urine and plasma samples by using Tox-Elut solid phase extraction columns and identification through UV/Vis absorbance spectrum comparisons with a reference library.
