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.

Pioneers in biomarker research

Almost all of the biomarker methods developed at ABF were published in peer-reviewed journals, a fact that supports the validity, transparency and scientific evidence of the bioanalysis especially of importance for regulatory submissions
