中文摘要:
      利用大气压电喷雾电离-液相色谱-质谱联用(API-ESI-LC-MS)技术分离和检测丁三醇三硝酸酯(BTTN)和丙三醇三硝酸酯(NG)的二元混合物,BTTN和NG的分离用反相高效液相色谱在C18柱上进行,在225 nm处实施。乙醇-水(1:1,V/V)混合液为流动相,流速为0.2 ml·min-1.研究了CapEx电压、pH值的变化、反吹气温度、电离方式对BTTN和NG质谱的影响。结果表明,用负离子方式检测,CapEx电压、pH值分别为-100 V和7,反吹气温度为100 ℃时可得到较理想的质谱图。

英文摘要:
      The binary mixture of BTTN and NG was separated and determined by means of simultaneous techniques of API-ES-LC-MS. Through the reversed-phase high performance liquid chromatography,BTTN and NG were separated on the C18 column. The detection was performed at 225 nm. The mobile phase was a mixture of methanol and water(1:1,V/V) at a flow rate of 0.2 ml·min-1. The influence of CapEx voltage,pH of sample solution,temperature of a counter flow of neutral,heated dying gas(T) and ionization mode on the mass spectra of BTTN and NG was studied. The results show that under the conditions of CapEx voltage=-100 V,pH=7 and T=100 ℃,the perfect mass spectra of BTTN and NG were obtained using the negative ion mode.
