The use of porous monolithic matrix for matrix-assisted laser desorption/ionization time of flight mass spectrometry analysis on a sample suspected of containing an analyte is herein described. The porous polymer monoliths provide a matrix suitable for use in detecting and analyzing low molecular weight and small molecules. The matrices described herein also facilitate the creation of arrays of monolithic matrices for high-throughput detection and screening using MALDI-TOF mass spectrometry and exhibit a long shelf-life.
