Preparation Note

This vial contains a concentrate of a blended gasoline from three different sources and diesel fuel oil No. 2 in pentane for analysis by TNRCC Method 1005.
When prepared according to instructions, the concentration of each analyte will be less than 100 mg/L.
The packsize on this sample has recently changed from 2ML to 1.2ML. This change does not affect the performance of the proficiency test.

Sample preparation

To prepare solution, fill a 40-mL voa vial to volume with carbon-filtered reagent-grade water at room temperature.
Remove enough water to allow for the addition of extraction solvent.
Open vial PE1619-1.2ML and immediately withdraw 40 μL with a gas tight syringe.
Quickly inject the 40 μL aliquot below the surface of the reagent water in the voa vial.
Add the extraction fluid.
Mix the sample by inverting the flask three times only (excessive shaking results in loss of volatiles) and analyze immediately. Assume a 40mL sample for calculation purposes.
Note this is a 1:1000 dilution and other dilutions are acceptable.
