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.

Wellington Laboratories are committed to the distribution of quality products as well as the maintenance of excellent customer service. In fact, in order to provide your customers with the best possible service, Wellington have three ISO certifications (ISO 9001:2008, ISO/IEC 17025:2005, and ISO Guide 34:2009) which cover all aspects of planning, production, testing, distribution, and post-distribution service. These certifications allow Wellington Laboratories to monitor and maintain the highest level of quality and service and also allow their customers to satisfy the requirements of their own ISO certifications.

Wellington’s ISO/IEC 17025:2005 accreditation has been certified by the Canadian Association for Laboratory Accreditation Inc. (CALA) the scope is available for review on the CALA Directory of Accredited Laboratories (http://www.cala.ca).

Similarly, Wellington’s ISO Guide 34:2009 accreditation has been certified by ANSI-ASQ National Accreditation Board (ANAB), the certificate and scope are available on their website (http://anab.org/).

We are able to supply hard copies of any of the ISO certificates for yourself and your customers.
