Several polyoxymethylene (POM) model compounds with relatively low molecular weights were characterized by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) using dithranol matrix, 1,1,1,3,3,3-hexafluoro-2-propanol solvent for matrix/analyte solution, and sodium iodide as cati
