Trace LC-MS/MS Analysis of Hormones in Tap Water and After Purification to Laboratory Grade

Hormones are examples of contaminants of emerging concern (CEC) that have been detected in environmental and drinking waters around the world in trace amounts. Even at very low concentrations, CECs could potentially exert ecotoxicological effects. In this application note, three hormones were detected by LC-MS/MS in the tap water of different laboratories. After purification by Milli-Q® water purification systems, the hormones were no longer detected in the product ultrapure water.
