“…Normally, such profiling analysis is performed by gas chromatography (GC) with a flame ionisation detector (FID) [1][2][3][4][5][6], although GC in combination with a electron capture detector (ECD) [2], nitrogen phosphorous detector (NPD) [6], and mass spectrometry (MS) [3] have also been used for this purpose. As early as 1973, Strömberg [2] used a packed OV-17 column (3% www.elsevier.com/locate/forsciint Forensic Science International 169 (2007) 50-63 diphenyl, 97% dimethyl silicone) to separate target compounds in Leuckart amphetamine in 26 min, and detection was accomplished simultaneously with a FID and a ECD.…”
