Gas chromatography/resonance-enhanced multiphoton ionization time-of-flight mass spectrometry (GC/REMPI-TOFMS) was applied to the measurement of a sample of raw material, the main component of which was bisphenol A di(2-hydroxypropyl) ether, which is a bisphenol A propylene oxide 2 mol adduct (BPA-2PO). Consequently, the peak for the main component could be ionized and detected via ultraviolet laser...
The effect of solvent on the solution inlet/laser vaporization technique for multiphoton ionization/time-of-flight mass spectrometry (MPI/TOF-MS) was examined. In this technique, a sample of dibenzofuran, dissolved in an organic solvent, is introduced underneath the nozzle for jet expansion through a narrow capillary, at the end of which a glass frit is formed to vaporize the solvent and to deposit...
