Environmental Monitoring

Teach Me in 10

As per- and polyfluoroalkyl compounds become more prominent, the US Environmental Protection Agency (EPA) are developing more stringent regulations for PFAS monitoring. 

In this Teach Me in 10, we hear from field application scientist Marc Elie on the challenges of PFAS analysis in matrices including drinking water and wastewater and how to mitigate interference and contamination on LC-MS/MS instrumentation. 

After watching, you’ll understand the differences between analysis for US EPA Methods 537.1, 533 and 1633 as well as the additional difficulties of PFAS analysis in non-potable water.

Understanding Animal Research

Although zebrafish have been used in research for sixty years we can still learn about their preferences. Watching zebrafish in the wild and studying their ecology can help scientists do this.

Jamie Woodward is a professor of Physical Geography at The University of Manchester where he leads a group exploring microplastic contamination in rivers. He is a geomorphologist – his research examines environmental change and how people interact with rivers from the Nile Valley to the River Mersey. In this Teach Me in 10, you will learn: That river beds can be heavily contaminated with microplastics, why monitoring microplastic contamination on river beds is important, how microplastics accumulate on river beds in high concentrations,  microplastic assemblages can be used to identify poor wastewater practice, why effective wastewater treatment is key to protecting river ecosystems and how ocean currents transport microplastics to the Arctic.

How to use a pressurized solvent extraction system

Learn how to relieve helium gas shortage issues by quickly adapting your iConnect SSL injector to dramatically reduce helium consumption to a few mL/min during operation and to almost no flow when the GC is idle. Extend the helium cylinder lifetime from months to years according to the usage of the instrument. The Thermo Scientific HeSaver-H2Safer technology is useful as well when hydrogen is used as carrier gas. In this case, this technology eliminates safety concern and the additional cost of H2 sensor installation. Know more from this video about how it works and discover the benefit of saving costs by maintaining your validated methods unchanged.
