Abstract: A Study on High Resolution Fast Atom Bombardment Mass SpectrometryCheng Guangrong; Cao Shulan; Zhang Gang (Laboratory of Mass Spectrometry, Liaoning Province Analysis, Testing and Research Centre, Shenyang 110015, China)Reveived 1993-11-09 Abstract:A new high resolution fast atom bombardment mass spectrometry (HRFABMS)method different from photogrophic detection peakmatching and multichannel analyzer has been studied in this paper. It uses a non-ionic surface active agent as interal standard material different from CsBr, CsI and KI , and it is the matrix. The data processing method is also given.Keywords:HRFABMS, matrix, internal stanard material.
