Also referred to as Potable Water or Water Supply sample, this sample is produced according to TNI requirements. However, please note, this sample may include non-TNI analytes as well. The lower criteria from the TNI tables mimic the levels common to drinking water samples. The PT portfolio allows our test components to offer significant performance data to monitor and prove competency to customers, accreditation bodies or both.

Preparation Note

Description

  • This PT sample is packaged as a 1.2 mL concentrate.
  • The solvent for this sample is acetone.
  • The PT sample is not preserved.
  • The sample must be stored at 4 °C.

Sample Preparation


  • Fill a 1000 mL Class A Volumetric Flask with 900 mL of organic-free reagent water.
  • Allow the ampule concentrate to equilibrate to room temperature.
  • Open the ampule and pipet exactly 1.0 mL of the concentrate into the flask.
  • Fill to volume and mix well.
  • This represents the sample for analysis. Report results in μg/L.
  • This set contains two ampules for the organochlorine pesticides.
  • For your convenience, the analyst may prepare and analyze each ampule individually or combine the contents of both ampules to have only one extract.
  • If analyzing each ampule independently, follow the enclosed preparation instructions. If both ampules are to be combined, add the required amount from each ampule to the same volumetric flask. Do not mix the flask until both ampule portions are added.
  • It is advised that the analyst review the reporting forms for each ampule in the set to determine if the preparation and analysis methods utilized will provide adequate identification of the compounds before combining ampules to one flask.

Storage and Stability

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