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 packaged as a 20mL concentrate. The solvent for this sample is 5% nitric acid by volume in DI water. The PT sample has not been preserved.

Sample Preparation

To prepare solution, partially fill a 1000mL volumetric flask with reagent-grade water (near 20ºC) and add 1mL of trace-metal-grade nitric acid.
Shake ampule well prior to opening.
Open ampule 1132-20ML (be careful to avoid cuts on glass) and transfer 10.0 mL of concentrate to the volumetric flask.
Fill the flask to volume with reagent-grade water and mix well.
The sample is now ready for immediate analysis.
A reagent-grade blank should be analyzed concurrently for background correction. The water blank should be made to match the acid matrix of the standards and samples.
Each analyte is reported in μg/L.
Note - The 0.15% v/v nitric acid specification is a minimum; the amount and type of acid may be altered to routine analytical procedures if needed.
Note - Mercury can be present as both inorganic and organic mercury.

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.
