    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 co-chaired 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 also presented 2 platforms and 3 posters at the conference.

     

    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:

    • Fluorotelomer sulfonates (FTSs). FTSs are PFCA-precursors which are often observed at elevated concentrations (even exceeding the concentration of PFOS and PFOA) around sites of aqueous film foam (AFFF) application. AXYS has developed new methods for the quantitative analysis of FTSs in solid and aqueous matrices, including specific handling protocols for high-level samples which are common around AFFF-discharge sites.
    • Polyfluoroalkyl phosphate esters (PAPs) in aqueous and solid matrices. PAPs are a recently identified class of PFCA-precursor which have proved to be challenging to measure in samples due to their high surface activity. These substances are high production volume chemicals widely used in the food-contact paper and packaging industry. AXYS has developed new methods for the quantitative analysis of mono- and di-PAPs in solid and aqueous matrices.
    • Perfluorooctane sulfonamides (FOSAMs) and Fluorotelomer acids (FTAs) -Perfluorooctane sulfonamides and fluorotelomer acids are intermediates in the degradation of commercial surfactants and coatings to perfluoroalkyl acids (e.g. PFOS, PFOA). AXYS has developed new methods to measure both FOSAMs and FTAs simultaneously in solid and aqueous matrices.

    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.
