ABSTRACT:
The invention involves apparatus, reagents, and methods for determining a disinfecting effective amount of hypochlorite in a sample. These involve using enough neutralizing agent sufficient to neutralize up to, but no more, than 0.525%, or 5250 parts per million, of hypochlorite in a sample. If more than this amount is present in the sample, then an indicator system reacts with it to provide a detectable signal, such as color. If the hypochlorite is present at less than 0.525%, no signal forms. One can determine this in two minutes or less.
