The fragmentation patterns of synthetic Escherichia coli-type lipid A in plasma desorption mass spectrometry (PDMS) in both negative-and positive-ion modes were determined. Negative-ion spectra gave signals for the main diphosphorylated (intact) molecular species in their native proportions. Intact
A new on-target deuteration technique in plasma desorption mass spectrometry (PDMS) is proposed, involving replacing labile hydrogen atoms in a molecule with deuterium atoms. This technique is very simple and allows direct comparison of spectra before and after deuteration for the same probe. The ut
The use of an electrostatic particle guide (EPG) for background reduction in a time-of-flight mass spectrometer is described. Operating with reverse polarity, the EPG deflects ions radially from the beam axis, separating the ionic and neutral components of the beam. Use of the deflection EPG in a sy
