摘要The atmospheric pressure chemical ionization/time-of-flight mass spectrometry(APCI/TOF-MS) was applied to determine the mass of five α-allenic alcohols via their protonated molecular ions using positive ion mode. Polyethylene glyclo (PEG) was used as the internal reference. All results were obtained under the resolution of about 5000 FWHM (full width at the half maximum). Solvent effects were studied and the satisfied results were obtained in acetonitrile. Compared with the theoretical values, all absolute arrors were less than 1.0 mmu. The effects of nozzle potential, push pulse potential, pull pulse potential, pull bias potential and acquisition rate on exact mass determinaion were also discussed. APCI/TOF-MS is proven to be a very senstitve analytical technique and an alternative ionization mode in analyzing thermally labile compounds with relatively weak polarity, such as α-allenic alcohol.
