Just dip it: online coupling of “Dip-it” polymer monolith microextraction with plasma assisted laser desorption ionization mass spectrometry†
Abstract
A polymer monolith microextraction (PMME) procedure coupled to plasma assisted laser desorption ionization mass spectrometry (PMME-PALDI-MS) was developed for rapid and organic solvent-free trace analysis. The extraction device used a “Dip-it” sampler coated with a MWNT incorporated monolith, and the analytes adsorbed on monoliths were effectively desorbed by laser, improving detection sensitivity.
