摘　　要：A GC-MS method for analysis of amino acid compositions in fingermark residues was established.Sample was extracted by ethanol and derivatized with N-methyl-N-(trimethylsilyl)trifluoroacetamide for 6 min at 600 W of microwave.The recovery,repeatability,detection limit,and linear equation were investigated.The results indicated the method was rapid,sensitive and effective,and was very helpful for the development of fingerprint technique.A GC-MS method for analysis of amino acid compositions in fingermark residues was established.Sample was extracted by ethanol and derivatized with N-methyl-N-(trimethylsilyl)trifluoroacetamide for 6 min at 600 W of microwave.The recovery,repeatability,detection limit,and linear equation were investigated.The results indicated the method was rapid,sensitive and effective,and was very helpful for the development of fingerprint technique.
