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 blended gasoline from three different sources 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 preparationFill a 100-mL volumetric flask to volume with carbon-filtered reagent-grade water at room temperature. Open ampule PE1798-2ML (be careful to avoid cuts on glass) and immediately withdraw 20 muL. Quickly inject the 20 muL aliquot into the reagent water in the expanded area of the volumetric flask. Mix the sample by inverting the flask three times only (excessive shaking results in loss of volatiles) and analyze immediately
