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 physical chemical parameters in natural waters (ex. drinking water, mineral water, groundwater, etc.).

Parameters

  • Alkalinity
    (25 - 400 mg/L CaCO3)
  • Ammonium
    (0.10 - 1.50 mg/L NH4)
  • Bromide
    (50 - 300 microg/L)
  • Calcium
    (10 - 150 mg/L)
  • Chloride
    (10 - 200 mg/L)
  • Conductivity (20 oC)
    (100 - 1500 microS/cm)
  • Fluoride
    (0.50 - 5.00 mg/L)
  • Magnesium
    (2 - 40 mg/L)
  • Nitrate
    (5 - 50 mg/L NO3)
  • Nitrite
    (0.10 - 2.00 mg/L NO2)
  • Permanganate index
    (1 - 20 mg/L O2)
  • pH (20 oC)
    (6.5 – 9.5 U)
  • Phosphate
    (1.50 - 15.0 mg/L PO4)
  • Potassium
    (1 - 50 mg/L)
  • Sodium
    (5 - 100 mg/L)
  • Sulphate
    (10 - 300 mg/L SO4)
  • Total Dissolved Solids (Dried at 180°C) (100 - 1500 mg/L)
  • Total Hardness
    (5 - 30 oF )
  • Total Organic Carbon (TOC)
    (0.5 - 10 mg/L C)
  • Turbidity
    (2 - 30) NTU

Proficiency test item:

  • 1 x 1000 mL of the test material ready to use for the determination of all parameters except Permanganate index, TOC and Turbidity.
  • 1 x 1000 mL of the test material to be prepared from a natural water matrix and a vial of the spiking solution for the determination of Permanganate index and TOC.
  • 1 x 1000 mL of the test material to be prepared from a natural water matrix and a vial of the spiking solution for the determination of Turbidity.
