The Field Nitrate Test Kit showing Nitrate Test Standards.

 F-NTK 101 provides the following Reagents and Tools:

  • Clear and Easy to Follow Instructions
  • Nitrate Reductase (NaR) - 1 tube in amber bag
  • NADH - 1 tube in amber bag
  • Assay Buffer (AB) in liquid form - one 30 ml tube
  • Color Reagent (CR) in solid form – one 60 ml amber bottle
  • Quench Agent (QA) - 1 tube in amber bag
  • Nitrate Standards in liquid form - 3 tubes
  • 19 Plastic Test Tubes with caps - 15 samples, 3 standards, 1 blank
  • 4 Small Pipets - 3 labeled with colored tags
  • 3 Large Pipets
  • 1 Test Tube Rack
  • 1 Field Data Sheet
  • 1 Color Chart - Standard Range (0.5 to 10 ppm Nitrate-N)

User Supplies Needed:

  • Watch, stopwatch or timer
  • Deionized or distilled water (di-water, nitrate-free)
  • Marker for labeling reaction tubes
  • 15 small sample tubes (clean, nitrate-free)

On the day you are going to the field to measure nitrate, you prepare the reagents in 5 easy steps, which are clearly explained in the F-NTK instructions.  You collect up to 15 samples in the field in your sample containers - use small containers since you need 1 ml or less.  Next you do the nitrate tests in 4 easy steps, which takes less than 1 Hour to complete.  Finally, you evaluate the results for your samples using the Nitrate Standards and the Color Chart and record the results on the Field Data Sheet provided.  Nitrate content of samples are determined semi-quantitatively by the F-NTK with an accuracy within 1 ppm nitrate-N.   Clean up is easy because all the reagents are non-hazardous chemicals.  You can simply dump them down the drain (if your local regulations allow you to do so).   You are exposed to no dangerous chemicals when using the NECi F-NTK and there is no significant damage to the environment when the reagents are spilled or disposed.
