Features and Benefits

We have a vast portfolio of environmental PT schemes with "fit-for-purpose" samples to help you meet the needs of the laboratory.

Our proficiency testing (PT) program is a benchmark to:

  • provide staff with an insight into their laboratory′s performance, to verify the accuracy and reliability of their testing process
  • provide a comparison of performance with that of other laboratories, nationally and internationally
  • test and educate staff, provide a better understanding of the impact of incorrect results and identify areas where there may be problems
  • provide an independent evaluation of laboratory performance
  • demonstrate to clients, colleagues and accreditation bodies that there is a commitment to quality

Preparation Note

  • This PT sample is packaged as a 1.5 g concentrate.
  • This ampule contains one or more Polychlorinated Biphenyl (PCB) as an Aroclor mixture in transformer oil.
  • The PT sample is not preserved.

Sample Preparation
  • To prepare the solution, weigh a clean, dry 100-mL volumetric flask to the nearest 0.1 mg.
  • Open ampule PE1275-2ML (be careful to avoid cuts on glass) and transfer approximately 1 g of the material to the volumetric flask; reweigh the flask to the nearest 0.1 mg and calculate the weight difference.
  • Fill the volumetric flask to volume (100 mL) with pesticide-grade hexane and mix well.
  • Transfer the remainder of the material from PE1275-2ML to a PTFE-lined screw-cap vial and store for future use.
  • All analytes are reported in mg/kg of oil. Do not report diluted concentration. The result should be reported as the oil concentration and not diluted concentration.

Storage and Stability

Please refer to sample label for expiration date, specific storage temperature, and specific storage conditions.
