Description

General description

This proficiency testing sample is produced in accordance with ISO/IEC 17043:2010. All information regarding the use of this material can be found in the reporting packet supplied for each sample.

Preparation Note

This PT sample is a solid concentrate.
The matrix for this sample is NaCl.

Sample Preparation
Partially fill a 1000 mL volumetric flask with reagent-grade water.
Open container PE1050-1.5G and transfer entire contents to volumetric flask.
Transfer to the volumetric flask using a glass funnel.
Rinse the vial, cap and funnel with reagent-grade water and transfer to volumetric flask.
Fill the volumetric flask to volume (1000 mL) and mix by inverting the flask 10 times.
Allow sample to rest for 10 minutes and invert 10 more times.
Immediately after the second set of inversions, rapidly measure a 500-mL aliquot into a graduated cylinder by repetitively mixing and pouring so as not to allow solids to settle in the flask before the transfer is complete.
The sample is now ready for immediate analysis.
Filter this 500 mL aliquot and determine the analytes according to the chosen method(s).
Remember to correct back to 1000 mL.

Other Notes

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