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 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 preparation
Fill a 100-mL volumetric flask to volume with carbon-filtered reagent-grade water at room temperature.
Open ampule PE1817-2ML (be careful to avoid cuts on glass) and immediately withdraw 20 μL. NOTE: This is a 1 to 5000 dilution.
Quickly inject the 20 μL 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
