Abstract

Infrared and ultraviolet matrix-assisted laser desorption Fourier transform mass spectrometry is investigated using a number of different matrices. In common with previous reports, it is found that the most efficacious matrices, regardless of laser wavelength used, are those which absorb at the chosen wavelength. Effects of matrix/analyte ratio, laser power, and choice of matrix under low pressure Fourier transform mass spectrometry conditions are examined.
