Product Technical Specification:

Why Hydrazine is replace by Carbohydrazide ?
Carbohydrazide (CH6N4O) - RXSOL-42-2541-025 is an oxygen scavenger often added to boiler systems to control corrosion. It reacts with oxygen at low temperatures and pressures. It also passivates metal surfaces preventing further corrosion. The reaction products are volatile, so they do not contribute to dissolved solids in the system. Carbohydrazide is widely used to replace hydrazine as an oxygen scavenger because it is less toxic.

DPD Powder

Size:

Color:

Product Short Description: A reagent that reacts with disinfectants like chlorine, chloramines, chlorine dioxide, and ozone to create a pink solution
Product Technical Specification:
DPD (N,N-diethyl-p-phenylenediamine) is used in free chlorine colorimetric analysis since it reacts with Hypochlorous acid and Hypochlorite ions acquiring a pinkish color that can be quantitatively related to the concentraction of those substances if it's inside the working range, DPD-Method can't be used in very high concentrations of free chlorine.
