Paper doi abstract bibtex In this work, an extremely simple and quite sensitive mass spectrometric method termed ambient surface-assisted laser desorption/ionization mass spectrometry (ambient SALDI-MS) was developed to analyze different kinds of compounds, just using a piece of graphite-coated paper for the sample introduction. This provides great advantage in simplifying the analysis process. The method is quite easy to use, and there is no need to worry about the source of graphite, that is, the brands or the types of pencil. And the whole process was carried out under atmospheric pressure, offering all the merits that could occur in ambient MS. The improved sensitivity of this method is mainly because of the graphite, which serves as energy-transfer medium to absorb the energy of the photons and release it to the analytes that are adsorbed on the graphite surface. Also, three different laser wavelengths (1064, 532, and 355 nm) was tested to investigate the desorption mechanism. Fifty-one compounds, with varied chemical structures, were tried to prove that this new method possessed universal applicability to detect different kinds of small organic molecules.
