Carsten Baessmann, the Director of Applications Development at Bruker Applied Mass Spectrometry, will be giving a talk on “Monitoring emerging contaminants like PFAS beyond regulatory requirements using trapped-ion-mobility QTOF MS in combination with newly developed non-targeted workflows.”
This meeting will occur on Tuesday, May 20th, from 12 pm – 1 pm EST.
Abstract: Environmental pollution remains a critical global challenge as the ecosystems are continuously exposed to a diverse and dynamically changing mixture of anthropogenic chemicals, including emerging contaminants (ECs), PFAS and Dioxins. Their vast number, including metabolites and transformation products, combined with the lack of mass spectral libraries and analytical standards, hinders their identification. Moreover, ECs and PFAS are often present at low concentrations in the environmental compartments and the occurrence of matrix interferences complicates their identification. Therefore, it is essential to employ comprehensive analytical techniques and workflows capable of identifying the “chemical fingerprint”. High Resolution Mass Spectrometry (HRMS)-based workflows are powerful tools for the simultaneous detection of emerging pollutants, covering a wide range of substances with diverse applications and physicochemical properties, including their metabolites and transformation products. Additionally, Ion Mobility Spectrometry provides an additional dimension of separation, enhancing the identification of chemicals in complex matrices. The objective of our studies was to evaluate the capabilities of Trapped Ion Mobility Spectrometry (TIMS) in the established targeted and untargeted LC-HRMS workflows in combination with smart software tools for the in-depth monitoring of emerging contaminants, Dioxins and PFAS in complex environmental and food matrices.
Our next webinar will be on June 17th (corrected date) and will feature updates from BP4NTA working groups. Webinars will continue to be held on the third Tuesday of each month at 12 pm US Eastern time for the remainder of 2025 (July 15, August 19, September 16, October 15, November 19, and December 16). We are still recruiting speakers, so please reach out if you may be interested in presenting. Be aware that if you received a previous event invitation in Outlook (would be from James McCord) that the May meeting is the last one scheduled in that series. You may wish to add the others to your calendar separately, as our new email system does not allow bulk sending of outlook attachments.
Coming up June 1-5 is the American Society for Mass Spectrometry meeting in Baltimore, Maryland, and we anticipate that many BP4NTA members will be in attendance. If you are interested in meting up with other BP4NTA folks, please reach out to Sonja Klee, BP4NTA secretary.
