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.

This ampule contains a concentrate of a No. 2 Diesel in methanol. This PT sample is packaged as a 1.5 mL concentrate. The solvent for this sample is methanol. The PT sample is not preserved. Sample preparationTo prepare solution, fill a 1000-mL volumetric flask to volume with carbon-filtered reagent-grade water at room temperature. Open ampule PE1708-2ML (be careful to avoid cuts on glass) and immediately withdraw 1 mL. Quickly inject the 1 mL aliquot into the reagent water in the expanded area of the volumetric flask. Mix the sample by inverting the flask three times only and analyze immediately. Note: This sample may be used for method AK102 SV (small volume). To ensure sample integrity, we recommend preparing the same small volume as you normally test. For instance, if your small volume sample is 125 mL, the PT should be diluted 125 uL of concentrate to 125 mL of water (1:1000 dilution).
