In addition they are highly soluble and some degrade over an extended time period slowly, and as a result some PPCPs are detected in soil and higher up the food chain also. For this reason the US EPA stringently monitors trace concentrations of PPCPs. Liquid chromatography with mass spectrometry delivers the selectivity and sensitivity to detect PPCPs at trace levels required by legislation. The application note explores the high sensitivity of the EVOQ in detecting PPCPS in clean water. Several water samples had been analyzed for a range of PPCP species including plain tap water samples along with bottled and creek drinking water.
