Scope of the Interlaboratory Proficiency Testing

The scope of this proficiency testing is the evaluation of the performance of laboratories for the determination of the Polycyclic Aromatic Hydrocarbons (PAHs) in natural waters (ex. groundwater, surface water, etc.).

Polycyclic Aromatic Hydrocarbons (PAHs)

  • Acenaphthene (83-32-9)
    (10 - 200 ng/L)
  • Acenaphthylene (208-96-8)
    (10 - 200 ng/L)
  • Anthracene (120-12-7)
    (10 - 200 ng/L)
  • Benzo[a]anthracene (56-55-3)
    (10 - 200 ng/L)
  • Benzo[a]pyrene (50-32-8)
    (5 - 100 ng/L)
  • Benzo[b]fluoranthene (205-99-2)
    (10 - 200 ng/L)
  • Benzo[k]fluoranthene (207-08-9)
    (5 - 100 ng/L)
  • Benzo[g,h,i]perylene (191-24-2)
    (5 - 100 ng/L)
  • Chrysene (218-01-9)
    (10 - 200 ng/L)

  • Dibenzo[a,h]anthracene (53-70-3)
    (10 - 200 ng/L)
  • Fluoranthene (206-44-0)
    (10 - 200 ng/L)
  • Fluorene (86-73-7)
    (10 - 200 ng/L)
  • Indeno[1,2,3-cd]pyrene (193-39-5)
    (10 - 200 ng/L)
  • Naphthalene (91-20-3)
    (10 - 200 ng/L)
  • Phenanthrene (85-01-8)
    (10 - 200 ng/L)
  • Perylene (198-55-0)
    (10 - 200 ng/L)
  • Pyrene (129-00-0)
    (10 - 200 ng/L)

Proficiency test item:

  • 1 x 2000 mL of the test material to be prepared from a water matrix and a vial of the spiking solution for the determination of all parameters.

ANALYSIS: The test sample should be analysed under the same conditions and with the same procedures used for the routine samples in the laboratory including the quality control procedures.

For each measurand shall be reported the result of a replica.

ADDITIONAL RESULTS: Each participant can submit up to 5 results* for the same analyte, thus obtaining an evaluation of laboratory performance for different operators, instruments and/or test methods (e.g. operator 1/operator 2, instrument A/instrument B, etc..).

*: Only one result submitted by the laboratory will be included in the statistical treatment of data for the calculation of the Assigned Value and statistics of data of the analyte, to avoid that a single laboratory has a different statistical weight, depending on the number of its submitted results. The additional results are evaluated by assigning z-score values, using the Assigned Value and the Standard Deviation for Proficiency Assessment obtained from statistical treatment.
