| Abstract: | In the analysis of oligopeptides,nucleosides and other polar organic com-
ounds,negative ion chemical ionization mass spectrometry using mixed methane and
dichloromethane as reagent gas can provide information aboutM+Cl]~- ion and molecu-
lar structure and cause less damage to the filament than that using dichloromethane only.
The proper experimental conditions as well as the results and the limitations of this meth-
od are also described. |
