SKU:
RXSOL-62-2541-002
Packing Sizes: 
RXSOL convenient visual test kits utilize PDTS chemistry to test for carbohydrazide. The test develops a peach-pink colored complex within 1 minute that is then matched to a color comparator. Readings are obtained in ppm (mg/L) carbohydrazide.
Product Application: 
Why Test for Carbohydrazide?
As an oxygen scavenger, carbohydrazide is a critical component employed to prevent corrosion within a system. Testing for carbohydrazide ensures the dosing of systems with sufficient chemical to protect metal from corrosion but not so much that treatment chemicals are wasted. Regular testing therefore ensures maximum efficiency of the boiler system.
Product Dose: 
The PDTS Method : Reference: G. Frederick Smith Chemical Co., The Iron Reagents, 3rd ed., p. 47 (1980). The test kits employ the PDTS chemistry. Carbohydrazide Reduces Ferric iron to the Ferrous state, and the Ferrous iron reacts with PDTS (3-(2-pyridyl)-5,6-bis (4-phenylsulfonic acid)-1,2,4-triazine disodium salt) to form a peach-pink colored complex in direct proportion to the carbohydrazide concentration. Test results are expressed as ppm (mg/L) carbohydrazide.
Product Note: 

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.
