| 摘要 |
The invention relates to a process for the analysis of molecules having a molecular weight of <1500 Da by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), wherein an analyte containing low molecular weight molecules is applied to a matrix material, which is characterized in that the matrix material comprises fullerene-derivatised silica. This process allows clear identification of small molecules through intensive signals without matrix -related background disturbances.
