DPD Nitrite Powder Reagent

Overview

DPD nitrite reagent measure nitrite, which means two different things depending on where you stand. In a closed heating circuit it is a dosed corrosion inhibitor to be held above a minimum; in drinking water or a wastewater process it is an intermediate that signals incomplete nitrification.

Key features

• Serves both nitrite inhibitor control and nitrification monitoring
• Ready-made reagent, so there is no weighing or dilution on the bench
• Supplied in the 20 g size, item code PLpow20DPDNitr

Frequently asked questions

Why does nitrite appear in a wastewater plant?
Nitrite is the halfway house between ammonia and nitrate. A figure that will not come down usually means nitrification is incomplete, often through low oxygen or a shortage of alkalinity.

Does this reagent work on its own?
Several photometric methods use two or three reagents in sequence. Check which components your method lists, and we will make sure the set is complete before it ships.

How should liquid reagents be stored?
Cool, dry and out of direct sunlight, with the cap firmly closed. Note the batch and expiry on the bottle, and work through the oldest stock first.
