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 1.5 g concentrate.
This ampule contains one or more Polychlorinated Biphenyl (PCB) as an Aroclor mixture in transformer oil.
The PT sample is not preserved.

Sample preparation
To prepare solution, weigh a clean, dry 100mL volumetric flask to the nearest 0.1mg.
Open ampule PE1275-2ML (be careful to avoid cuts on glass) and transfer approximately 1g of the material to the volumetric flask; reweigh the flask to the nearest 0.1mg and calculate the weight difference.
Fill the volumetric flask to volume (100 mL) with pesticide-grade hexane and mix well.
Transfer the remainder of the material from PE1275-2ML to a PTFE-lined screw-cap vial and store for future use.
All analytes are reported in mg/kg of oil. Do not report diluted concentration. The result should be reported as the oil concentration not diluted concentration.

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.
