title: Screening by tandem mass spectrometry for trace levels of alkylbenzenes.
abstract: Product ion spectra derived from molecule ions as the precursor ions for 14 alkylbenzenes have been studied under electron ionization and methane chemical ionization. The data have provided a satisfactory screening method for both detection and confirmation of such compounds at low parts per million levels.
