Product Description:
Pt/Si Catalyst (Platinum on Silica), Part Number 88400-0535, is a premium, high-purity catalyst specifically designed for use in combustion gas analyzers. Engineered with finely dispersed platinum on a high-surface-area silica support, this catalyst is essential for promoting complete oxidation of hydrogen and carbon-containing gases during high-temperature combustion analysis in ONH, CHS, and TGA systems.

In advanced elemental analyzers, the Pt/Si catalyst acts as a post-combustion converter, ensuring that residual gases like hydrogen (H₂) and carbon monoxide (CO) are fully oxidized to water vapor (H₂O) and carbon dioxide (CO₂). This step ensures the accuracy and consistency of trace-level gas measurements by reducing interference and increasing detector sensitivity.

• High Surface Area Silica Support – Maximizes platinum dispersion and reaction efficiency
• Complete Gas Oxidation – Converts CO and H₂ into measurable CO₂ and H₂O
• Enhances Detection Accuracy – Improves signal quality and analytical reliability
• Protects Analyzer Components – Reduces residual gas interference and detector contamination
• Wide Compatibility – Optimized for LECO®-style analyzers and thermal analysis systems

Role in Combustion Analysis:
The Pt/Si catalyst is placed in the gas path after combustion to facilitate the final oxidation of incomplete combustion products. This ensures that only fully oxidized gases reach the detector (typically IR or TCD), which is critical for accurate measurement of hydrogen, oxygen, and carbon in materials such as metals, ceramics, and chemicals.

Without this catalytic step, unconverted gases could lead to inaccurate results, instrument contamination, and reduced analyzer lifespan.

Ideal For Use In:

• ONH and OH Elemental Analyzers – Precision detection of oxygen, nitrogen, hydrogen
• CHS and Carbon-Sulfur Analyzers – Enhanced conversion for carbon and sulfur accuracy
• Thermogravimetric Analysis (TGA) Systems – Supports decomposition reactions and gas evolution
• Combustion and Thermal Modules – H-500, Surface C-800, TIC Modul, and more

Applications:
Used extensively in metallurgical laboratories, materials research, chemical analysis, and industrial QA/QC labs, the Pt/Si catalyst ensures complete combustion and dependable trace gas quantification.
