AXYS at SETAC 2013: Session chairs, platform and poster presentations in Nashville, TN November 17 to 21
AXYS’ analytical leadership is founded on scientific excellence. AXYS will co-chair 2 sessions at SETAC - “Occurrence, Fate, and Behavior of Per- and Polyfluoroalkyl Substances in the Global Environment” and “Advances in Environmental Metabolomics”, both with the US EPA. AXYS will also present 2 platforms and 3 posters at the conference and a number of AXYS clients will also be presenting at the conference. Click here to find a selection of additional sessions.
AXYS expands offering for analysis of per- and polyfluorinated substances
Per- and polyfluoroalkyl substances (PFASs) constitute a diverse class of chemicals which have been globally manufactured since the 1950s and continue to be in use today. Perfluoroalkyl acids (PFAAs, including PFOS and PFOA), are the most commonly studied PFAS due to their widespread occurrence in the environment, including human blood and remote arctic wildlife. The occurrence of PFAAs can arise from direct commercial use, but also from the degradation of precursor substances (i.e. PFAA-precursors). To aid researchers in understanding and characterizing sources of PFAA exposure, AXYS is pleased to announce the development of new methods for the quantitative analysis of the following PFAA-precursors:
AXYS offers the widest range of PFAA and PFAA-precursor analysis of any commercial lab. Contact our Sales staff today to learn more.
AXYS expands Naphthenic Acid method to additional matrices
Through continual improvement processes, AXYS has implemented method updates for the Naphthenic Acid method to expand into solid and tissue matrices. This method has direct application to fingerprinting projects related to the oil sands. Please contact AXYS Sales staff to learn more.
AXYS develops a combined PPCP and Hormone method for POCIS media
AXYS has developed a combined method to test for PPCP and Hormones in POCIS. The test allows clients to test for 162 compounds from 1 sample, which reduces sampling costs without impacting detection limits. Contact AXYS Sales staff today to learn more.
AXYS' Dr. M. Coreen Hamilton receives the 2013 Caledon award
The 2013 Caledon award, which recognizes a Canadian who has made “significant scientific, technological or administrative contributions in the analytical chemistry of trace organic residues”, was awarded to Dr. Hamilton at the 48th Annual Western Canada Trace Organic Workshop in Vancouver, BC in May 2013.
