- Ionic Strength Adjusting Solution (ISA) adjusts the pH of standards and samples used in ammonia measurements.
- Ammonia Standard Solutions; 0.1 M ammonium chloride or 1,000 ppm as N.
Replacement Membranes or Membrane Caps; Loose membranes for probes with O-Ring membrane holder; membrane caps for probes with threads to mount membrane.
Nitrate Test Kit
- Permits use of Ammonia Electrodes to measure nitrate
Kit solutions are used to make sample basic and then to convert nitrate to ammonia for measurement. Ions such as chloride, which normally interfere, have no effect on the measurement. Includes 475 mL bottle of alkaline reagent (4209N85), 475 mL bottle of 100 ppm nitrate as nitrogen standard, 475 mL bottle of 100 ppm ammonia standard, two 50 mL bottles of filling solution and reagent delivery syringe.
