Wellington Laboratories is a producer and supplier of high quality reference standards for compounds of environmental concern worldwide.

We continually strive to provide new and innovative products to meet the ever changing and growing demands of environmental analysis and research.

Our reference standards include chlorinated dibenzo-p-dioxin (PCDD) and dibenzofuran (PCDF) congeners and many mass-labelled analogues of these compounds. We also have a comprehensive selection of mass-labelled PCB congeners, including all of the congeners that have been identified as “dioxin-like” in their toxicological activity.

Welington also provides ready-to-use solution sets to meet the regulatory requirements for the analysis of PCDDs/PCDFs and PCBs in many countries.
