Native Potassium Perfluoro-4-ethylcyclohexanesulfonate (PFECHS) Wellington Laboratories

Hydraulic Fluid a Likely Source of Contamination

     

NEW PRODCUT - Native Potassium Perfluoro-4-ethylcyclohexanesulfonate (PFECHS)


Perfluoro-4-ethylcyclohexanesulfonate has been primarily used as an additive in hydraulic fluid formulations that are designed to inhibit erosion in hydraulic systems. The use of the hydraulic fluids in commercial aircraft was identified as a likely source of this compound in surface waters and fish from the Great Lakes of North America; PFECHS contamination is now being reported internationally. PFECHS itself exists as a pair of cis and trans isomers, but commercial materials also contain substantial impurities including constitutional isomers that exhibit the same mass-to-charge ratio as PFECHS during mass spectrometric detection. Unfortunately, the use of inadequately characterised reference standards increases the uncertainty associated with the generated data. For this reason, Wellington Laboratories has prepared a certified reference standard (chemical purity > 98%) which contains a known ratio of the cis/trans isomers of PFECHS (as determined by 19F NMR).

Wellington Laboratories and Greyhound Chromatography working in partnership to bring Testing and Analysis Laboratories the best Reference Standards and Materials on the market. For Over 35 years Wellington Laboratories Inc. and Greyhound Chromatography have been internationally recognised as trusted sources of high quality reference standard solutions for use in environmental / analytical testing and toxicological research.

Wellington Laboratories offers an extensive inventory of individual certified reference standards and solution mixtures of native and mass-labelled halogenated organic compounds including polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans, polychlorinated biphenyls, halogenated flame retardants and perfluorinated compounds. Wellington Laboratories also offer a variety of calibration sets and support solutions designed to be used for common regulatory methods or modified in-house methods.

Wellington Laboratories Certified Reference Standards of Native HBCD Enantiomers

Wellington Laboratories Certified Reference Standards of Native HBCD Enantiomers

(+) aHBCD,  (-)aHBCD, (+)gHBCD & (-)gHbcd

1,2,5,6,9,10-Hexabromocyclododecane (HBCD) is an additive flame retardant that is listed under Annex A of the Stockholm Convention for elimination due to its potential persistence and toxicity.  It has been reported to be present at percent levels in extruded and high-impact polystyrene foams and to a lesser extent in electricakl equipment housings.  The HBCD technical product is composed of three main diastereomers (alpha, beta, and gamma) which are routinely analysed for in environmental matrices.  Varaition in the physicochemical properties among these stereoisomers leads to differential biological uptake and degredation rates resulting in the measurement of non-racemic HBCD distributions.  For this reason, Wellington Laboratories has produced certified reference standards for the enantiomers of alpha-HBCD (which is typically dominant in biotic matrices) and gamma-HBCD (which is typically dominant in abiotic matrices as well as the commercial mixture to aid researchers in the accurate determiation of these stereoisomers.

BFR 2017 Conference, York, UK

BFR 2017 Conference, York, UK 

Hosted by Fera Science Ltd, BFR 2017 took place from Sunday 7th to Wednesday 10th May 2017 in York, UK.  Platinum Sponsors for the event were Greyhound Chromatography UK and Wellington Laboratories, Canada.

The 'International Symposium on Flame Retardants' is a series of conferences on safety aspects of flame retardants. The conferences bring together international experts from industry, governments and academia to exchange latest research results and to propose measures to reduce risk from the use of flame retardants.

Scientific topics included Heath effects, Epidemiology, Organophosphate flame retardants, Fire safety, Flame retardants in biota, Food, Flame retardants in abiotic environments, Analytical methods, Exposure, Policy and regulation.

In line with earlier BFR conferences, selected papers submitted to BFR2017 are  published in a special issue of Chemosphere on BFR2017. Immediately after the symposium, authors were invited to submit their paper for the special issue. All submissions were fully peer reviewed.  The special issue guest editors are Dr. Martin Rose, Dr Alwyn Fernandes and Prof.Dr. Jacob de Boer.

Visit  www.bfr2017.co.uk  to view the full conference programme and access the Conference Abstracts.  

You can  access 2017 abstracts  here.

Previous BFR conference abstracts are available from the website.
