Environmental Analysis (Dioxins, Furans, PAHs, PCBs)

All of our environmental analysis services are driven by the following values;

  • Attain accreditation to the highest national and international standards
  • Use of world class technology
  • Recruit, develop and retain experts in chemical analysis
  • Continuous improvement of methodology, QA / QC protocols to ensure the highest data quality
  • On time delivery of results in a format that suits your requirements

We are able to provide;

  • International Toxicity Equivalent (ITEQ) determinations of polychlorinated dibenzo-p-dioxin (PCDD) and dibenzofuran (PCDF) compounds
  • Analysis of the World Health Organisation listing of 12 polychlorinated biphenyls (PCBs) congeners (WHO 12)
  • Polycyclic aromatic hydrocarbons (PAHs)

Validated methods have been developed, enabling material groups of specific environmental interest to be identified and quantified including;

  • Volatile organic compounds (VOCs)
  • Semi-volatiles

 

 

Dioxins and Furans

Produced inadvertently by industrial processes such as waste incineration, chemical manufacturing and paper bleaching, dioxins and furans can be found in the air, in water and contaminated soil. As they accumulate they can become harmful to human health.

High-resolution mass spectrometry is the US EPA accepted analytical technique for quantifying dioxins and furans. Our expert staff utilize state of the art, proven techniques to accurately determine Dioxin and Furan emissions to the lowest levels, to ensure you can optimize the safety of your operations.

Stationary Source Emissions:

We undertake UKAS accredited Dioxin analysis to BS/EN 1948, the European harmonized protocol for stack measurements from hazardous waste incinerators as well as to USEPA Method 23. This includes the preparation and supply of XAD traps for sample collection.

Other Matrices:

Accredited Dioxin analysis methods to USEPA 1613 for soils, sediments, waters, waste waters, ash and dust have been developed. Other methods are also available.

Our state of the art instrumentation and sample preparation facilities combined with optimised methodology ensure the highest quality data, a swift turnaround time and highly competitive pricing, including a fast turnaround premium service for urgent samples.

We are constantly seeking ways to improve our service by reducing sample preparation time, analytical costs and detection limits. Full method blanks with each sample batch and appropriate QC sample preparation ensure confidence in our analytical results. Limits of detection are calculated separately for each targeted congener in each sample, giving a more accurate assessment of matrix interference.
