Combined Use of Fused Silica Capillary Columns and Nitrogen-Phosphorus Detection for the Toxicological Analysis of Illicit Heroin Samples

Abstract

Capillary GC is applied to the toxicological analysis of illicit heroin samples. The combined use of a permanently deactivated fused silica capillary column, and a nitrogen-phosphorus detector (NPD), allows the separation and determination of nanogram amounts of underivatised opiates, using a direct injection technique.
