Diesel in Water, PT Concentrate for dilution to 1 L, Proficiency Testing Material, MilliporeSigma™ Supelco™

Description

• This ampule contains a concentrate of a No
• 2 Diesel 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 preparationTo prepare solution, fill a 1000-mL volumetric flask to volume with carbon-filtered reagent-grade water at room temperature
• Open ampule PE1708-2ML (be careful to avoid cuts on glass) and immediately withdraw 1 mL
• Quickly inject the 1 mL aliquot into the reagent water in the expanded area of the volumetric flask
• Mix the sample by inverting the flask three times only and analyze immediately
• Note: This sample may be used for method AK102 SV (small volume)
• To ensure sample integrity, we recommend preparing the same small volume as you normally test
• For instance, if your small volume sample is 125 mL, the PT should be diluted 125 uL of concentrate to 125 mL of water (1:1000 dilution).
