Trace Chemical Analytics Lab

LC-MS

The Institute of Environmental Sciences provides quantitative analysis and technical expertise to members of the Institutes’ community, other research facilities, and industry needing to conduct measurements. The cutting-edge facility allows students and researchers to perform accurate and precise analysis on a range of environmental samples such as sediment, soil, vegetation, water, suspended matter, pollen and insects. The state-of-the art fully-automated Agilent equipment used in the facility achieves high-throughput, high-sensitivity, and high-resolution separation and quantitation of trace levels of compounds (e.g. plant protection products, pharmaceuticals, personal care products, mycotoxins, proteins, etc.) even in the presence of highly abundant matrix interferences. To provide high quality analysis, the facility also houses a range of extraction/isolation and purification methods to aid in preparing complex samples for analysis.
