The sources and chemical structures of the main fragments are interpreted. All of the eight compounds give the base peak of m/z 143. The main fragments are from the α cleavage and its rearranging ones at the carbonyl gronp.展开更多

The method can be applied in forensic and sanitary identification of amfepramone. There is a linear relationship within the ranges of 0.2-1ug. The regress equation: Y=-0.37+2.36X; r=0.993 S=0.088. The recovery is 87.3%.展开更多

We used Diazepam as internal marking method to cap out correcting quantitation. The regress equation: P Y=1423+401077X, r=0.997; A Y=19329+771338X, r=0.995; N Y=10880+92690X, r=0.996, The precision: P CV=6.9%, A CV=5.2%; N CV=1.8%. The recovery: P=77%; A=82%; N=87%. The minimal detecting amount: p=100ng; A=50ng; N=10ng. The method is accurate, rapid and simple. It can provide scientific evidence for The forensic identification and clinical diagnostics.展开更多

The method is a simple, rapid, high sensitive and accurate solution. The minimum detection amount of Daconil is around 0.2ug. Daconil is a bit sensible to fish. Currently, some criminals pot it into pool to poison fish. There are several cases like this in our province. We detected pool water by GC/MS and GC and achieved a correct conclusion. Daconil is detected in pool water.展开更多
