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 20 mL concentrate.
  • Definition of a dissolved metal: Those metals in an unacidified sample that pass through a 0.45 μm membrane filter.
  • The solvent for this sample is 1% nitric acid by volume in DI water. The sample is slightly acidified to maintain stability in the concentrate and will not interfere with the method. Please follow preparation directions for best performance.
  • The PT sample has not been preserved.

Preparation Instructions

  • To prepare the solution, partially fill a 1000 mL volumetric flask with reagent-grade water (near 20 ºC).
  • Shake ampule well prior to opening.
  • Open ampule PE1038-20ML (be careful to avoid cuts on glass) and transfer 10.0 mL of concentrate to the volumetric flask.
  • Fill the flask to volume with reagent-grade water and mix well.
  • The sample is now ready for immediate analysis. Please note that the sample has not been acidified, you will need to acidify as required by your method after filtration.
  • A reagent-grade blank should be analyzed concurrently for background correction. The water blank should be made to match the acid matrix of the standards and samples.

Storage and Stability

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