title: [Gas chromatography with dual nitrogen-phosphorus detection and flame ionization detection for screening abuse drugs].
abstract: A dual-detection Gas chromatographic method for screening out abuse drugs is described. A single capillary separation column is connected to a nitrogen-phosphorus detection (NPD) and a flame ionization detection (FID) by an Y-connector. The ratio responded by NPD/FID is influenced by operational conditions. But the relative ratio is not influenced when carbetane is used as a reference. The ratio and the relative ratio can be used to screening abuse drugs.
