Biomonitoring

We offer a broad range of LC-MS and GC-MS based methods for the quantitative determination of environmental chemicals and/or their specific metabolites in various biological matrices, such as urine, serum, plasma or saliva. Our methods are frequently used on biomonitoring campaigns to evaluate the (non-)occupational exposure to environmental chemicals.
