AN1100: Determination of Benzo[a]pyrene in Municipal Drinking Water Using Automated Solid-Phase Extraction and Liquid Chromatography with Fluorescence Detection

Instrument Type: HPLC

A Dionex AutoTrace 280 solid-phase extraction instrument was used to reduce analyst intervention and automatically complete SPE column activation, sample loading, and the elution and collection of Benzo[a]pyrene. The eluted samples were solvent exchanged and concentrated to a defined volume, and then trace Benzo[a]pyrene in municipal water was measured using HPLC with fluorescence detection.

Sensitive and Rapid Determination of Polycyclic Aromatic Hydrocarbons in Tap Water

Instrument Type: HPLC

This method describes an on-line SPE HPLC method with UV absorbance and fluorescence detections for rapid and sensitive determination of 20 PAHs in tap water. The determination is performed on a Thermo Scientific UltiMate 3000 Dual RSLC system combined with a Thermo Scientific Hypersil Green PAH analytical column. Reduced MDLs for UV and fluorescence detection, enabled by on-line SPE using the Thermo Scientific Dionex Acclaim PA2 column, provide a convenient method for determining these compounds in drinking and environmental waters using HPLC.
