Nota de preparo


  • This PT sample is packaged as a 1.2 mL concentrate.
  • The solvent for this sample is methanol.
  • The PT sample is not preserved.

Sample Preparation

  • Fill a 100 mL Class A Volumetric Flask to volume with organic-free reagent water.
  • Open ampule PE1250-1.2ML and withdraw 20 μL of the solution using a gas-tight microsyringe.
  • Inject the concentrate into the expanded area of the flask well below the surface of the water.
  • Stopper the flask and mix by gentle inversion 3 times. Excessive mixing will result in loss of volatiles and should be avoided.
  • This represents the sample for analysis.
  • DO NOT USE a matrix simulator with this sample.
