Popis: Picogram amounts of underivatized chlorophenols and chlorocresols are analysed by gas chromatography mass spectrometry using high resolution selected ion monitoring. Deactivation by pretreatment of columns with 2,4-dichlorophenoxyacetic acid gives long-term improvement in sensitivity and reproducibility.
