Methods of Analysis by the U.S. Geological Survey National Water QualityLaboratory: Determination of Pesticides in Water by Graphitized Carbon-Based Solid-Phase Extraction and High-Performance Liquid Chromatography/Mass Spectrometry

摘要

In 1996, the U.S. Geological Survey National Water Quality Laboratory (NWQL)developed and implemented a graphitized carbon-based solid-phase extraction and high-performance liquid chromatographic analytical method to determine polar
