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.

The Echo® MS+ system is a novel platform for Acoustic Ejection Mass Spectrometry (AEMS) and combines the speed of acoustic sampling with the selectivity of mass spectrometry. This platform has been designed for high throughput analysis of small and large molecules. The technology combines Acoustic Droplet Ejection (ADE), an Open Port Interface (OPI) and could be coupled with the SCIEX Triple Quad 6500+ system or the ZenoTOF 7600 system.
The Echo® MS+ system comprises of an open-port interface (OPI) and acoustic droplet ejection (ADE) module which could be coupled with a mass spectrometer. The mass spectrometer could either be a SCIEX Triple Quad 6500+ system or the ZenoTOF 7600 system. This non-liquid chromatography based; high-throughput screening platform enables rapid analysis of compounds at speeds of up to 1 sample/second.
The ability to consistently achieve reproducible results on many complex samples across multiple days is critical to a routine clinical laboratory. Laboratories relying on analytical instrumentation require stability and robustness to perform a variety of screening and confirmatory assays with confidence. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) has become the preferred analytical method in the clinical laboratory to reliably perform clinical testing as it provides best-in-class performance and reliability for the most challenging assays. LC-MS/MS offers the required levels of sensitivity and specificity for the detection and quantitation of molecules from complex biological samples, helping laboratories deliver highly accurate data for a variety of clinically relevant analytes across a wide range of assays.
