SCIEX is no stranger to drinking water analysis, and the Environmental Compendium once again addresses the topic in an application note which covers LC-MS/MS with Fast Polarity Switching. Using the QTRAP® 5500, researchers were able to detect a large panel of Pharmaceuticals and Personal Care Products (PPCP’s) while performing fast positive/negative switching all from a single injection. Method details go the distance in this application note, as five experiments were called into action for comparison.Download Environmental Compendium >
Why Test for PPCP’s in Drinking water?Not all wastewater treatment processes are created equal and can leave behind trace amounts of influent PPCP’s. While the amounts are considered minimal, they have been known to cause disruption to aquatic life, thus the reason for ultra-low analysis in the lab. Numbers vary, but thousands of PPCP’s are known to be in existence and depending on the substance, some have shorter shelf lives than others. Insulin, for example, can expire as soon as 30 days after a bottle is open and if flushed, can enter freshwater if removal isn’t effective at the treatment plant. We may not be able to live without our pharmaceuticals and personal care products, but in the Environmental Compendium, researchers report how you can better test fresh water samples for PPCP’s in the parts per trillion range.
Want to learn more about PPCP analysis? The Environmental Compendium has pages of application notes dedicated to the topic, and we want to share them with you!

Trifluoroacetic acid (TFA) is emerging as one of the most concerning ultrashort-chain PFAS in Europe’s food supply – particularly in cereals, a staple consumed daily by millions. A report from PAN Europe reveals a widespread and largely unmonitored contamination trend that raises serious questions about food safety, regulatory blind spots, and future monitoring strategies.
PFAS analysis is complex, but expert guidance doesn’t have to be. In this episode of our ‘Ask the PFAS expert series’, we’re joined by Michael Scherer, Application Lead for Food and Environmental, to answer the most pressing questions in PFAS analysis. From why LC-MS/MS systems are the gold standard for analyzing diverse PFAS compounds, to which EU methods deliver reliable results for drinking water, and to practical steps to prevent contamination, Michael shares actionable insights to help laboratories achieve accuracy, consistency, and confidence in their workflows.
During an LC-MS/MS experiment, traditional fragmentation techniques like collision-induced dissociation (CID) have long been the gold standard. Electron-activated dissociation (EAD) is emerging as a transformative tool that enhances structural elucidation, particularly for complex or labile metabolites.
