Nitrosamines/Nitroaromatics - PT is a soils/hazardous waste proficiency testing material, suitable for testing explosives and explosive residue analytes in soil samples.

Our soil PT samples behave as real samples; and, unless there is no alternative, are not simply spikes added to a blank soil. They are designed to meet the requirements of national, regional and state-specific accreditation bodies (TNI, USEPA, UKAS) for quality assurance and continuous improvement.

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 trace levels of explosives and explosive residues.
  • The PT sample size provided is 30 g of soil.
  • The soil has been chemically stabilized to minimize degradation of the sample.
  • The PT sample has been sized to 100 mesh.
  • Required storage condition is 4º C.
  • The sample has been intentionally prepared with an apparent headspace.

Sample Preparation
  • Analyze the sample using the preparatory and determinative method(s) for which you are seeking accreditation. The sample was specifically designed for SW846 8330, but is suitable for equivalent methods. Nitroglycerin must be analyzed using method 8332.
  • If you are accrediting for more than one method make additional copies of the report form and clearly indicate the method used for the data being reported.
  • Determine the concentration and report your results and method on the analysis data sheet provided.
  • Results are to be reported on a wet weight basis.

Storage and Stability

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