What happens when you up the sensitivity and lower detection limits on influent and effluent sewage tests? For starters, low levels of illegal drugs in samples begin to emerge. This is what researchers discovered when they combined the power of LC-MS/MS with the Scheduled MRM™ algorithm using large volume injection techniques on a QTRAP® 5500 system. Limits of Quantitation (LOQ) was the word in this application note, as sample results following the “The Street Parade Zurich,” dipped well into the low ng/L range eliminating the need for multi-period experiments.Download Compendium >
Tests like these go beyond standard surveys such as, “Monitoring the Future 2015 Results,” from the National Institute on Drug Abuse. While helpful in reporting the number of people who have tried or currently use illegal drugs, the results are not scientifically adequate. Tests such as the ones reported in this tech note can lead to better process controls at wastewater treatment plants, therefore lessening environmental impacts.
The Science behind Influent Wastewater Drug TestingUsing a completely redesigned LC method, a core-shell LC column was used to test influent water samples around the timing of the parade. This tech note is a must read for anyone who wants to learn how expanded column dimension allowed for large volume direction injection minus the breakthrough of polar compounds like morphine. It is just one of the research applications in this year’s Environmental Compendium, conveniently available for download. From pesticides to PPCP’s, unknown screenings, perfluoroalkyl acids, explosives, and flame retardants we not only give you data but explain the methods and instruments used to obtain the results so your lab can improve your discoveries.

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.
