Abstract

A sample for analysis by Laser Desorption Mass Spectrometry is prepared by dissolving the sample material in a solvent and applying the solution to a matrix material applied to a target for a mass spectrometer. The matrix material is selected from the group consisting of (i) cis-Cinnamic Acid with the aromatic ring substituted by one or more groups which possess an electron pair on the atom adjacent to the ring; (ii) trans-Cinnamic Acid with the aromatic ring substituted by one or more groups which possess an electron pair on the atom adjacent to the ring; (iii) Benzoic Acid, with one or more substituent groups as described in (i); and (iv) Coumarin, with one or more substituent groups as described in (i).
