Preparation Note

Sample Preparation

• This ampule contains a concentrate for preparation of a solution that can be analyzed for bromide, chloride, fluoride, nitrate nitrogen, nitrite nitrogen, sulfate and orthophosphate phosphorus in water.
• To prepare solution, partially fill a 1000 mL volumetric flask with reagent-grade water (near 20 °C).
• Open ampule PE1060-20ML (be careful to avoid cuts on glass) and transfer 10.0 mL of the concentrate into the volumetric flask.
• Fill to volume (1000 mL) with reagent-grade water and mix well.
• The sample is now ready for immediate analysis.

Note - A blank of reagent-grade water should be analyzed concurrently for background correction.

Storage and Stability

Please refer to sample label for expiration date, specific storage temperature, and specific storage conditions.
