Nitrate Information

$91.00

The K-6909B Nitrate Kit was designed to accurately measure the levels of Nitrate in water from 0-675 ppm. K-6909B uses the Cadmium Reduction Method. Nitrate is reduced to nitrite using cadmium as the reducing agent. The resulting nitrite concentration is then determined colorimetrically. This method is applicable to drinking and surface waters, as well as domestic and industrial wastes. Nitrite will interfere with this test. Results are expressed as ppm (mg/L) NO3-N or NO3. 

Nitrate is the most completely oxidized form of nitrogen. It is formed during the final stages of biological decomposition, either in wastewater treatment facilities or in natural water supplies. Low-level nitrate concentrations may be present in natural waters. However, a Maximum Contaminant Level of 10 ppm nitrate-nitrogen has been established for drinking water by the USEPA. 

Shelf-life: The refill and color comparator contained in this kit have shelf-lives of 12 months

R-6909 Refill Package includes 30 tests and can be purchased separately.

What's included:

  • 30 Ampoules
  • Comparator
  • 25 uL MiniPet
  • 25 mL Sample Cup
  • Reaction Tube and Cap
  • Instruction Manual

  

 

How to use:

  1. Place a yellow pipette tip firmly onto the end of the MiniPet
  2. Depress the plunger on the MiniPet. Immerse the tip in the sample and release plunger drawing in sample.
  3. Depress the plunger over the reaction tube to expel sample.
  4. Dilute sample to the 15 mL mark with distilled water
  5. Empty the contents of 1 Cadmium Foil Pack into reaction tube. Shake vigorously for 3 minutes.
  6. Allow sample to sit undisturbed for 2 minutes.
  7. Add 10 mL of the treated sample to the sample cup.Fill the sample cup to 25ml
  8. Insert the ampoule tip first into the sample, and snap the ampoule tip.
  9. Mix ampoule by inverting several timesTip the vacu-vial back and forth to mix
  10. Dry the ampoule, and wait 10 minutes for color development.
    Dry vacu-vial and then insert into the I-2019
  11. Obtain results using the appropriate comparator and finding the best color match.
