This PT sample is provided as a concentrate requiring dilution into reagent water.
The PT sample can be evaluated for each analyte listed on the report form.
If there are any analytes in the above list you wish not to be evaluated for, leave the associated line blank on the report form.
This PT sample is packaged as a 1.5 mL concentrate.
The solvent for this sample is acetonitrile.
The PT sample is not preserved.
The sample must be stored at 4 ºC.

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.

Other Notes

Proficiency testing samples are presented as single blind. No values for the samples are released unti the testing period concludes. Values of analytes vary lot to lot.
