Creator:

Busetti, Francesco, Backe, Will J., Bendixen, Nina, Maier, Urs, Place, Benjamin, Giger, Walter, and Field, Jennifer A.

Abstract:

The time-honored convention of concentrating aqueous samples by solid-phase extraction (SPE) is being challenged by the increasingly wide spread use of large-volume injection (LVI) liquid chromatography-mass spectrometry (LC-MS) for the determination of traces of polar organic contaminants in environmental samples. Although different LVI approaches have been proposed over the last...
