Sample Preparation

  • To prepare the solution, partially fill a 100 mL volumetric flask with aqueous acetone solution.
  • Open ampule PE1311-1.2ML (be careful to avoid cuts on glass) and immediately withdraw 1.0 mL using a class A pipette.
  • Quickly inject the 1.0 mL aliquot into the aqueous acetone solution in the expanded area of the volumetric flask. Bring the flask to volume with acetone.
  • Mix the sample by inverting the flask.
  • This represents the sample for analysis. Do not perform any additional extraction.
  • Aqueous acetone solution is defined in "Standard Method for the Examination of Water and Wastewater - Method 10200 H".
