金属血卟啉络合物的四甲基硅烷／甲烷的化学电离质谱

DEP-TMS/CH_4-CI Mass Spectrometry of Metallohematoporphyrin Complexes

本文以四甲基硅烷／甲烷混合反应气，采用ＤＥＰ技术，测定１２个金属血卟啉络合物的解吸化学电离质谱。通过分子离子ＭＨ＋，加合离子（Ｍ十７３）＋，以及吡咯环碎片离子可获得丰富的结构信息。

Desorption chemical ionization mass spectrometry of twelve metallohematoporphyrin complexes has been investigated under DEP condition using mixture of tetramethylsilane and methane as regent gas.Much structure information is obtained on the base of the molecular ion MH+,the additive ions [M+ 73]+ and the pyrrolic fragment ions.
