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

Description

  • This vial contains a concentrate of a blended gasoline from three different sources and diesel fuel oil No. 2 in pentane for analysis by TNRCC Method 1005.
  • When prepared according to instructions, the concentration of each analyte will be less than 100 mg/L.
  • The pack-size on this sample has recently changed from 2 mL to 1.2 mL. This change does not affect the performance of the proficiency test.

Sample Preparation

  • To prepare the solution, fill a 40 mL VOA vial to volume with carbon-filtered reagent-grade water at room temperature.
  • Remove enough water to allow for the addition of extraction solvent.
  • Open vial PE1619-1.2ML and immediately withdraw 40 μL with a gas-tight syringe.
  • Quickly inject the 40 μL aliquot below the surface of the reagent water in the VOA vial.
  • Add the extraction fluid.
  • Mix the sample by inverting the flask three times only (excessive shaking results in loss of volatiles) and analyze immediately.
  • Assume a 40 mL sample for calculation purposes. Note this is a 1:1000 dilution and other dilutions are acceptable.

Storage and Stability

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