Use
The ampoule has a predetermined breaking zone. Protect yourself by wearing gloves.Open the ampoule directly before useAtmospheric moisture canpenetrate in anopen ampouleor very dry air can absord water from theliquidand therefore falsify the results.For expiration data for the closed amooulesee label and Report of Analysis.
. Snap off the top tag of the ampoule at the predetermined breaking zone.
2. Rinse a glass syringe with approx.0.5 mL standard
3. Draw the rest of the standard immediately into the syringe.
4. Carryout 2-3 control determinations.
For monitoring the system or after the anayisis of a sample. add a known amount of Hydranal Water Standard and analyze it the same way as thesample. The amount of added water should be similar to the water amount in the sample.The recovery rate should ideally be within the expanded measurement uncertainty stated on the Report of Analysis.Literature gives varyingrecommendations forrecovervrateseq.the EuropeanPharmacopoeia
