What Is Carbohydrazide?
Carbohydrazide is a highly effective oxygen‑scavenging compound used to protect metal surfaces in boiler and steam‑generating systems. By reacting quickly with dissolved oxygen, even at relatively low temperatures, it helps form a protective passive layer on steel surfaces. This barrier reduces the likelihood of pitting, scaling, and long‑term corrosion.
One of the major advantages of carbohydrazide is that its reaction byproducts are volatile, meaning they do not contribute to dissolved solids in the system. Because of this, carbohydrazide has become a preferred alternative to hydrazine, offering strong corrosion control with significantly lower toxicity.
Why Test for Carbohydrazide?
Maintaining the correct concentration of carbohydrazide is essential for ensuring that a boiler system is properly protected.
- Corrosion Prevention: Adequate carbohydrazide levels ensure that oxygen is fully scavenged before it can damage metal surfaces.
- Chemical Efficiency: Overdosing wastes treatment chemicals, while underdosing leaves equipment vulnerable. Routine testing helps operators strike the right balance.
- System Performance: Stable carbohydrazide levels support consistent boiler operation and reduce maintenance costs.
- Operational Insight: Tracking trends helps engineers adjust feed rates and respond to changes in system load or water quality.
Regular monitoring ensures that the oxygen scavenger is doing its job—and that the boiler system is running at peak efficiency.
Our Carbohydrazide Test Kits
CHEMetrics carbohydrazide test kits provide a fast, straightforward way to measure carbohydrazide concentrations in boiler water and related systems. These visual kits use PDTS chemistry, which produces a distinctive peach‑pink color when carbohydrazide is present.
How the Test Works
- Add the sample to the test ampoule.
- Allow the color to develop—typically within one minute.
- Compare the resulting color to the included comparator.
- Read the concentration directly in ppm (mg/L).
This simple procedure makes the kits ideal for both field technicians and plant operators who need quick, reliable results without complex instrumentation.
