Chromatography and Analytical Techniques

Environmental Sample Analysis

Environmental sample analysis using chromatography has become indispensable in monitoring and managing pollutants across air, water, soil, and biota. Techniques such as gas chromatography (GC), liquid chromatography (LC), and capillary electrophoresis (CE) enable precise quantification of trace-level contaminants like pesticides, heavy metals, volatile organic compounds (VOCs), and persistent organic pollutants (POPs). Recent advances include high-resolution mass spectrometry (HRMS), two-dimensional chromatography, and automated solid-phase extraction (SPE), which have significantly improved sensitivity, selectivity, and sample throughput. Portable and field-deployable instruments now allow on-site analysis, accelerating decision-making in environmental monitoring. Regulatory bodies such as the EPA and EU REACH require validated chromatographic methods for pollutant detection and compliance reporting, further emphasizing their significance. Green analytical practices, including solvent recycling and miniaturized systems, are being incorporated to align with sustainability goals. This session explores the integration of cutting-edge chromatographic technologies with environmental science, focusing on innovative workflows, data handling, and regulatory standards to better understand and mitigate environmental risks.
