Copper(II) Oxide (CuO), Part Number 90289, is a laboratory-grade oxidizing reagent specifically engineered for use in ONH (Oxygen, Nitrogen, Hydrogen) and CHS (Carbon, Hydrogen, Sulfur) combustion analyzers. This high-purity CuO is critical in ensuring complete oxidation of sample materials during high-temperature combustion, allowing for accurate and reliable detection of elemental gases.

In advanced combustion systems, Copper(II) Oxide promotes full conversion of sample byproducts—particularly carbon monoxide (CO) and hydrogen (H₂)—into measurable gases like carbon dioxide (CO₂) and water vapor (H₂O), which can then be accurately quantified by the detector systems.

• Powerful Oxidizing Agent – Enhances combustion efficiency and gas conversion
• Ensures Complete Combustion – Converts CO and H₂ into CO₂ and H₂O for precise detection
• Supports Accurate ONH and CHS Analysis – Critical for consistent hydrogen and oxygen readings
• Prevents Incomplete Combustion Artifacts – Reduces baseline noise and false positives
• Broad Analyzer Compatibility – Trusted for use across multiple LECO®-style systems

Function in Combustion Analysis:
During elemental analysis, incomplete combustion can lead to underestimation of oxygen and hydrogen content due to the presence of residual CO or H₂. Copper(II) Oxide reacts with these residual gases to drive them to full oxidation. This step is essential for clean, reproducible results in trace-level elemental analysis.

Ideal for Use With:

• ONH and OH Analyzers – for accurate hydrogen and oxygen detection
• CHS and Carbon-Sulfur Systems – to ensure complete gas conversion
• Thermal and Gravimetric Analyzers (TGA) – supporting consistent decomposition and gas release
• Advanced Combustion Modules – where precision oxidation is essential

Applications:
Perfect for use in metallurgical labs, environmental analysis, ceramics, chemical manufacturing, and other industries requiring high-accuracy elemental combustion testing.
