About

Margo M. E. van der Kooi is a pioneering environmental chemist whose research focuses on the development of highly sensitive analytical methods for detecting trace-level organic pollutants in water. Her major contributions center on advancing solid-phase extraction (SPE) and gas chromatography (GC) techniques to meet stringent regulatory limits for pesticides, particularly achieving detection at concentrations as low as 0.1 μg/L. Her seminal 1995 paper, "Automated analysis of polar pesticides in water by on-line solid phase extraction and gas chromatography using the co-solvent effect," has garnered 31 citations, demonstrating its foundational role in the field. This work introduced an innovative co-solvent approach that dramatically improved the extraction efficiency of polar pesticides, enabling automated, high-throughput analysis without labor-intensive off-line pre-concentration. Van der Kooi’s methodologies have become essential tools for environmental monitoring agencies and water quality laboratories worldwide. Her achievements include pioneering the integration of on-line SPE with GC, which significantly reduced sample handling errors and analysis time. For students and researchers, her work exemplifies how method development can directly address critical environmental challenges, ensuring safer drinking water through precise, reliable contaminant detection.
