title: Positive and negative liquid secondary ion mass spectrometry of chloro- and nitrophenylglucuronides.
abstract: Mass spectra of a series of chloro- and nitrophenylglucuronides by liquid secondary ion (LSI) mass spectrometry were obtained. In the positive ion mode class characteristic fragmentations and adduct ions are observed only in the presence of alkali salt additives. No additives were necessary in the negative ion mode to see abundant class characteristic [M-H]- and aglycone fragment ions. Cluster ion formation was found to be prominent but only in the negative ion mode.
