Product Description:
Cellulose, Part Number 90340/90341, is a high-purity organic combustion aid used in elemental analysis systems to promote clean, complete combustion of solid and powdered samples. Composed of refined plant-based fibers, this cellulose material burns at high temperatures with minimal residue, providing a consistent carbon matrix that enhances combustion efficiency and analytical accuracy.

In ONH, CHS, and TGA analyzers, cellulose is commonly used as a sample carrier, combustion booster, or diluent, especially when analyzing low-mass or hard-to-combust materials. Its clean-burning properties help achieve total oxidation, ensuring accurate detection of elements like carbon, hydrogen, nitrogen, and sulfur.

• High Combustion Purity – Low ash content, minimal background interference
• Enhances Sample Combustion – Improves consistency and oxidation of sample material
• Uniform Particle Size – Ensures reproducible sample prep and analysis
• Non-reactive Carrier – Suitable for a wide range of organic and inorganic materials
• Compatible with LECO®-style and Elementrac® analyzers

Function in Combustion Analysis:
Cellulose is often mixed with samples to stabilize and support combustion, especially when sample mass is low or when a homogeneous mixture is required. It provides a predictable combustion environment, allowing analyzers to achieve full oxidation and deliver precise gas detection. Cellulose also helps maintain consistent sample delivery and positioning within crucibles or boats.

Ideal For Use In:

• ONH and OH Analyzers – Supports complete combustion for hydrogen and nitrogen accuracy
• CHS and Carbon-Sulfur Analyzers – Improves oxidation and repeatability for carbon and sulfur
• TGA and Thermostep Systems – Aids in controlled thermal degradation and weight loss analysis
• TIC and Surface Modules – Acts as a combustion matrix for carbon quantification in inorganics

Applications:
Widely used in metals analysis, coal and coke testing, cement and ceramics, and environmental laboratories, this cellulose ensures repeatable combustion reactions and dependable elemental detection in trace-level analysis.

Product Details:

• Part Number: 90340 or 90341
• Material: High-purity Cellulose
• Form: Powdered or fibrous (depending on analyzer specs)
• Packaging: Lab-sealed, contaminant-free container
