The United States Environmental Protection Agency (EPA), under the 1996 Safe Drinking Water Act (SDWA), requires a new list of no more than 30 unregulated contaminants to be monitored by public drinking water systems. Known as the Unregulated Contaminant Monitoring Rule (UCMR), a new list is published every five years. The last rule, UCMR3, was published May 2, 2012, and is the focus of the following application note, “Analysis of Perfluoroalkyl (PFFA) Acids Specified under the UCMR3 Using the QTRAP® 6500 LC-MS/MS system,” which can be found in the Food and Environmental Compendium.
OverviewUsing the guidelines laid out by EPA Method 537, “A Determination of Selected Perfluoroalkyl Acids in Drinking Water by Solid Phase Extraction and Liquid Chromatography/Tandem Mass Spectrometry (LC-MS/MS),” this application note describes the performance of the QTRAP 6500. Within the scope of EPA 537, there are 14 PFAAs. Six are specified under the UCMR3 monitoring list.
ProcessSample preparation and data processing were carried out according to EPA Method 537 without deviation unless specifically noted. The analysis was carried out using the QTRAP 6500 coupled with the Agilent 1260 HPLC with an Eksigent ULC 100 HTC-xt autosampler. Quantitation using MultiQuant ™ 3.0.
ConclusionThe lower the detection, the harder the QTRAP 6500 works for you as it easily meets the UCMR3 reporting limits. See what more it can do when you download the compendium. Download the compendium >
Useful FAQ document to enable researchers to focus on their scientific discoveries and insights rather than the complexities of data management.
In today’s environment in which labs are under pressure to reduce operating costs, many will compare the cost of a service contract between third-party providers and the original equipment manufacturer (OEM). At first glance, going with a service contract from a third-party provider may seem like a smart financial move, but experience shows they can introduce risks that affect reliability and compliance.
We recently hosted a webinar focused on streamlining forensic toxicology workflows, featuring expert speakers Maria Sarkisian from the San Francisco Office of the Chief Medical Examiner (SFOCME) and Dr. Dick Paul Kloos from the Netherlands Forensic Institute (NFI). The webinar explored innovative LC-MS/MS strategies that help forensic labs improve efficiency. In this blog, we share highlights from the Q&A session, where our speakers addressed the audience’s questions and shared actionable insights for forensic laboratory professionals.
