Samples must be analyzed immediately after collection and cannot be preserved for later analysis.
Let the sample temperature decrease to 50 °C (122 °F) or less before analysis.
Sulfite reacts quickly with oxygen in the air. Shaking or swirling the sample causes low results. Prevent agitation of the sample during the procedure.
Review safety chemical handling procedure. Use the recommended personal protective equipment. Dispose of reacted solutions according to local, state and federal regulations. Follow the environmental safety, health safety staff for your facility and/or local regulatory agencies for further disposal information.
Disposal
Ampoule may be discarded in regular trash services. Care should be taken not to cut yourself, or others, with exposed glass tip.
Shelf Life
Ampoules are accurate for two years after purchase, if tip is not broken.
Certification
The testing uses the 1-10 Phenanthroline method adopted from, “Standard Test Methods of Water and Wastewater” 15th edition 201 (1980). Fire sprinkler systems that contain high levels of dissolved iron and have been treated with Potter Pipe-Shield may still indicate high levels of corrosion when tested with the Potter iron test.
This is due to the fact the dissolved iron is still in the system. As the iron is flushed out during regular waterflow tests, flushing or draining the system for service, the tests will indicate less dissolved iron in the system.
2,4,6- Tris-(2’ - Pyridyl )-s-Triazine ( TPTZ ) or also can be use like 2,4,6-Tripyridyl-s-triazine. Solution of (TPTZ), .001 M were prepared by dissolving 0.312 gram of compound in a view drops of hydrochloric acid and diluting to 1 ltr with water.

Significance and Use:
Nitrate ions are present in trace amounts in surface water and in higher levels in some groundwater. Nitrate is found only in small quantities in domestic wastewater but can reach higher concentration (up to 30 mg/L as nitrogen) in the outflow of nitrifying biological treatment plants. Excessive amounts can contribute to methaemoglobinemia: infant death and adult illness. In order to prevent this, a 10 mg/L limit (as nitrogen) has been imposed on drinking water.
NOTE: mg/L is equivalent to ppm (parts per million).
Chemical Reaction:
Nitrates are reduced to nitrites in the presence of Cadmium. The nitrites thus produced react with the reagent to yield an orange compound. The amount of color developed is proportional to the concentration of nitrate present in the aqueous sample.
Safety Data Sheets:
The chemicals contained in this kit may be hazardous if improperly handled. Read the relevant Safety Data Sheet before performing this test.
