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


  • The PT sample is a soil containing total petroleum hydrocarbons (TPH).
  • The sample size provided is 100 g of soil.
  • The soil has been sterilized to minimize the degradation of the sample.
  • The PT sample has been sized to 100 mesh.
  • The evaluation of results will be based on study statistics as required by TNI.
  • The sample has been intentionally prepared with an apparent headspace.

Sample Preparation

  • The soil is to be extracted and analyzed using an appropriate extraction and analytical method for TPH, assuming a high concentration sample.
  • Mix well. No particle size reduction is necessary.
  • List the extraction technique and analytical method used for analysis of this sample.
  • Using the selected extraction technique and determinative methods, determine the concentration of TPH in the sample and report your results as mg/Kg on a dry weight basis on the analysis data sheet provided. Do not correct the analytical results for matrix spike recovery bias.
  • Determine moisture content and report on a dry weight basis.

Storage and Stability

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