摘要

Tne self-chemical ionization (SCI) in quadrupole mass spectrometry was developed to determine the structure of ( E)-2-iodo-3-( phenylslfinyl)-2-propen-1-ol and its 6 analogues.Some techniques that increase the sample quantity and heating speed and shorten vaporization time to obtain high pressure in the ion source were applied to increase the chance of ionmolecule reactions. Tne structures of these compounds were identified by mass spectral data of MH+ and stone characteristic fragment ions. Conpared with the mass spectra for 2-iodo-3-(phenylsulfinyl)-2-propen-1-ols obtained in electron impact ionization (EI), SCI showed more information, in particular, an improvement in amount of information at the high mass area. Tne absence of reagent gas makes the spectrumdean and sinple.
