The negative Ion chemical ionization mass spectra for 34 volatile metal chelates are reported. Also a sensitivity study using a gas chromatograph chemical Ionization mass spectrometer computer system comparing detection limits for several Cr(β-dlketonates)3 in both negative and positive Ion detection modes is described. This study Illustrates the ability of negative ion chemical ionization mass spectrometry to provide two to three orders of magnitude Increase In specific Ion currents for compounds containing electronegative functional groups.
