Suppression of low-mass ion peaks in matrix-assisted ultraviolet laser desorption has been found to occur at low matrix-to-analyte molar ratios when using nicotinic acid as matrix, independent of the angle of illumination. Microscopic Raman scattering spectroscopy has been employed to investigate th
