To 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.

This sample may be used for method AK102 SV (small volume). To ensure sample integrity, RTC recommends 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).
