ChromaBLOGraphy: What are GenX and PFBS? Why are they important in PFAS analysis?
Analysis of PFAS (per- and polyfluorinated alkyl substances) has been a hot topic for envoironmental labs for the last several years. Currently there are two C8 based PFAS compounds (PFOA and PFOS) with a health advisory level of 70 ppt in drinking water announced by the US EPA. In 2018 at the National Leadership Summit, […]

ChromaBLOGraphy: 7th International Symposium on Recent Advances in POPs Analysis
As mentioned in a previous blog, I was able to attend the 7th International POPs Symposium sponsored by Thermo Scientific at the Auditorium Santa Margherita in Venice, Italy and present work done on GC-HRMS analysis of chlorinated dioxins and furans on the Rtx-Dioxin2. The symposium was a veritable Who’s Who of noted scientists in POPs [...]
