DOI: 10.1007/s00216-020-03109-2
Abstract: A wide range of micropollutants can be monitored with non-targeted screening; however, the quantification of the newly discovered compounds is challenging. Transformation products (TPs) are especially problematic because analytical standards are rarely available. Here, we… read more here.
