      Wellington 1982年在加拿大成立,公司长期致力于为客户提供高质量的参考标准,参考标准包括氯化 dibenzo-p-dioxin(PCDD)和氧芴(PCDF)和许多类似mass-labelled这些化合物。有齐全的mass-labelled PCB同族元素,包括所有已经被认定为含“二恶英”的毒性。同时为很多国家提供多氯代联二苯对二恶英(PCDDs),多氯代二苯并呋喃(PCDFs),多氯联苯(PCBs)。

      Wellington主要产品:多氯联苯PCB同族元素、多溴联苯PBB、多氯代联二苯对二恶英(PCDDs)、多氯代二苯并呋喃(PCDFs)
 

  在二十世纪七十年代末期,多氯联苯是出了名的环境污染物,而氯化二恶英(PCDDs)和呋喃(PCDFs)则是最近才被认为是对环境有威胁的。此外,关于多氯联苯、氯化二恶英(PCDDs)和多氯代二苯并呋喃(PCDFs)的毒性的信息是极少的,尤其是关于它们长期的影响。

   当有相关文档记录显示多氯联苯(PCB)、氯化二恶英(PCDD)和多氯代二苯并呋喃(PCDF)的同系物是有显著的毒性,要比其他副产品更加有毒性之后, 对标准品这些化合物的需求迅速增长。然而,在商业上是很少有参考标准的这些化合物。

   由科学家们创办的威灵顿已经营了多年,对多氯联苯(PCB)、氯化二恶英(PCDD)和多氯代二苯并呋喃(PCDF)的同系物和其他卤代芳烃化合物合成个体来进行他们的研究。对这些化合物的样品和定制合成相关的化合物的需求已经势不可挡,惠灵顿的成立就是为了更快速和更有效响应对这些物品的需求。

   1983年1月,威灵顿发布第一个产品目录,提供多氯联苯(PCB)、氯化二恶英(PCDD)和多氯代二苯并呋喃(PCDF)的同系物。这个目录仅4页,囊括了大约75种个体化合物。

Wellington Laboratories Inc. (Wellington) was incorporated in February 1980, celebrating its 32nd anniversary in 2012.
In the late 1970’s, PCBs were known environmental contaminants, whereas chlorinated dioxins (PCDDs) and furans (PCDFs) had only recently been considered as threats to the environment. In addition, there was very little information as to the toxicity of PCBs, PCDDs and PCDFs, particularly long-term effects.

As it became more well documented that certain PCB, PCDD and PCDF congeners were quite toxic, and significantly more toxic than other congeners, the need for standards of these compounds grew rapidly. However, very few reference standards of these compounds were commercially available.

The scientists that founded Wellington had, for many years, synthesized individual congeners of PCBs, PCDDs, PCDFs and other halogenated aromatic compounds for their own research. Requests for samples of these compounds and custom synthesis of related compounds became overwhelming, and Wellington was formed to respond more quickly and efficiently.

In January 1983, Wellington released it first catalogue, offering PCB, PCDD and PCDF congeners. This catalogue was only 4 pages in length and listed approximately 75 individual compounds.

In the ensuing years, Wellington added more staff and lab space, and devoted itself to a considerable amount of research and development. This has led to the current catalogue, posted on this web site, which contains well over 1000 products.

Wellington will continue its research efforts with the goal of developing additional reference standards of compounds that pose a risk to environmental and human health.
