摘要:
A method of preparing a sample for matrix assisted laser desorption ionization mass spectrometry imaging analysis by a two-step process. Firstly, a MALDI matrix is dusted on to the sample followed by a spray of a suitable solvent onto the dusted sample. The present method has been successfully applied to the detection and mapping of several analyte classes in latent fingermarks. Using the present two-step method, fingermark enhancement, recovery and analysis from different substrate surfaces is now possible enabling visual and chemical information to be obtained simultaneously via remote testing.
