- Ammonia vs. Ammonium – what is the difference between these forms of . . .
Ammonia and ammonium are different forms of nitrogen The major factor that determines the proportion of ammonia to ammonium in water is pH The activity of the ammonia is also influenced by ionic strength and temperature It is important to remember as un‐ionized NH 3 can be harmful to aquatic organisms, while ionized ammonium is basically harmless The chemical equation that drives the

- Will the Ammonia (Nitrogen) Test Strips, 0-6. 0 mg L detect . . . - Hach
The Ammonia (Nitrogen) Test Strips, 0-6 0 mg L (Product # 2755325) will not detect quaternary ammonium compounds or residues The test strips work by raising the pH of the sample to above 10 which converts all ammonium ions in the sample to free (un-ionized) ammonia Quaternary ammonium cations are permanently charged cations, independent of pH, so they do not get converted to free ammonia

- Are Ammonia (NH3) and Ammonium (NH4+) different substances?
Ammonia (NH3) and Ammonium (NH4) are in equilibrium when dissolved in water The proportion of NH3 and NH4+ in the sample will vary based on pressure, temperature and most importantly pH In basic solutions ammonia is the dominant species This is important to note when comparing to other instrumentation that may read as NH3 or NH3-N
- What does the Amtax sc analyzer actually measure? - Hach
The Amtax sc analyzer adds Sodium Hydroxide (NaOH) to adjust the pH and convert ammonium ions (NH4+) to gaseous Ammonia (NH3) which passes through an Ammonia gas selective membrane and causes a pH shift of an electrolyte solution

- What is the recommended cleaning for a Ion Selective Electrodes (ISE . . .
Some ISEs use a PVC membrane with a special coating for selectivity specific to the ion of interest Some examples of probes with PVC membranes include: ISENO3181 and other Nitrate ISEs ISENH4181 and other Ammonium ISEs 9660C and other Calcium ISEs There are limited cleaning options for these electrodes The coating on these membranes can easily be damaged from the use of cleaning solutions
