Abstract

In the present study, a fully automated solid-phase extraction (SPE) system, a programmed temperature vaporization (PTV) interface, and gas chromatography (GC) with mass spectrometric (MS) detection are combined for the trace-level analysis of micropollutants in surface water. The PTV interface is selected because of its reliability regarding large volume injection and its robustness when analyzing real-life samples. The mass spectrometer was used both in the full-scan and the selected ion monitoring modes and gave detection limits of about 15-40 ng/L and 0.7-5 ng/L (7.5-mL samples), respectively, for a series of NP-pesticides.
