摘要
用基质辅助激光解吸电离飞行时间质谱(MALDITOFMS)研究了β环糊精对1,2二氢化3H1,2,4三唑3酮(TO)、3硝基1,2,4三唑5酮(NTO)的分子识别行为,研究了不同基体、基体浓度对其质谱图的影响。研究表明β环糊精对TO、NTO有很强的分子识别能力,以芥子酸为基体,基体复合物样品的摩尔比为10001时,这两种复合物的MALDITOFMS图均可得到基峰为复合物加氢峰,从而准确得出TO、NTO的分子量。
The molecular recognition of β cyclodextrin to 3 nitro 1,2,4 triazole 5 one (NTO) and 1,2 dihydro 3H 1,2,4 triazole 3 one (TO) was respectively studied by matrix assisted laser desorption/ionization time of flight mass spectrometry (MALDI TOF MS). The effects of different matrixes and concentrations on mass spectra were investigated. The results show that β cyclodextrin has strong recognition ability to NTO and TO. While the mole ratio of sinapic acid used as matrix and complex was 1001,the hydropeaks of the two kinds of complex used as base peak were determined by MALDI TOF MS ,so that the molecular weights of TO and NTO were accurately obtained.
