The reagent set contains powdered chemical components that are mixed to produce two liquid reagent solutions used during the analyzer’s automated measurement cycle. This chemistry allows the analyzer to measure combined chlorine plus free chlorine (total chlorine) with high precision for process control, regulatory compliance, and disinfection optimization.
Key Features
- Reliable DPD chemistry - Uses the N,N-diethyl-p-phenylenediamine (DPD) method, a standard approach for chlorine analysis in municipal and industrial water monitoring.
- Long shelf life (powder form) - Powder reagents offer extended storage stability when kept in a cool, dark, dry environment.
- Consistent reagent preparation - Each kit mixes into two 500 mL aqueous reagent solutions for analyzer operation.
What’s Included
The Total Chlorine Reagent Set contains three powdered components:
- Total Chlorine Indicator
- Total Chlorine Buffer
- DPD Powder
These components are prepared according to the 3017M reagent preparation procedure to produce two reagent solutions used during the analyzer’s automated measurement cycle.
Shelf Life and Storage
Proper storage is critical for maintaining reagent integrity and measurement accuracy.

Always check the expiration date on each individual component bottle. Store reagents in a cool, dry, and dark location to help maximize stability and shelf life.
Once hydrated and placed in the analyzer, reagent solutions are typically consumed over 1 month, depending on the analyzer’s measurement interval.
