UKAS Accredited Laboratory Analysis - ISO 17025: Fast, Efficient Service

Our purpose built air pollution environmental laboratory provides accurate and efficient analysis, specialising in the determination of gaseous pollutant concentrations. Other processes can also be performed to meet the specific needs of our customers.

Our laboratory is a UKAS accredited testing laboratory (No. 2187) to ISO17025:2017, this accreditation covers a number of our analysis methods.

Our laboratory analysis techniques include:

  • Thermal desorption.
  • Solvent desorption.
  • Gas chromatography – mass spectrometry (GC-MS).
  • Gas chromatography – flame ionisation detection (GC-FID).
  • Ion chromatography.
  • UV/visible spectrophotometry.

We also participate in several national quality schemes such as Air PT, LEAP and Field Intercomparison, giving us confidence in our analysis results. Details of our accreditation can be found in the Technical Library pages on this site.

Our highly skilled and experienced analysts allow us to perform wide ranging analysis on a variety of diffusion tube types. This is backed up by a knowledgeable technical advice department, who match individual customers requirements with the most suitable sampling equipment.

For analysis of air monitoring equipment, the following turnaround times apply. (Subject to full functioning of equipment. Longer periods may apply during the Christmas shutdown):

  • Standard analysis – 10 working days.
  • Fast-track analysis – 5 working days, by prior arrangement.
  • Premium fast-track – 2-3 working days, by prior arrangement.

Reports are sent electronically to customers so they are received in the fastest time possible.

Current pollutants for which we can analyse include Volatile Organic Compounds (VOCs), Nitrogen Dioxide (NO2), Hydrogen Sulphide (H2S), Ozone (O3), Ammonia (NH3), Sulphur Dioxide (SO2), Formaldehyde, Acid gases and BTEX (Benzene, Toluene, Ethylbenzene and Xylene).
