NH2NH2

Applications
- Power plants
- Cooling water
- Water steam cycle
- Boiler feedwater
- Control and optimization of oxygen scavenger systems
Description
Hydrazine is widely used in power generation plants to remove dissolved oxygen in boiler feed water and as a corrosion inhibitor. The analyzer can be used as a process monitor or discharge limit monitor, the single reagent configuration ensure minimum operating costs.
Method
Under acidic conditions, hydrazine reacts with p-dimethylaminobenzaldehyde to form a yellow-colored azine complex. The absorbance intensity is proportional to the hydrazine concentration in the sample and is determined at 470 nm.
Reagents
- Hydrazine reagent kit 1l r1
- Hydrazine reagent kit 2l r1
- Hydrazine reagent ready to use 1l r1
- Hydrazine reagent ready to use 2l r1
