Product Introduction & Main Application
Arnico’s Carbon Molecular Sieve (CMS) is an engineered carbonaceous adsorbent with a precisely controlled pore size distribution at the angstrom level, designed for gas separation based on molecular size discrimination. This material is specifically engineered for the production of high-purity nitrogen from compressed air in Pressure Swing Adsorption (PSA) systems, serving as the primary choice for supplying inert gas across a wide range of industries.

3. Features & Benefits
-
Superior Oxygen Selectivity: The precisely engineered pore structure enables a higher adsorption rate for oxygen compared to nitrogen, guaranteeing the production of ultra-high-purity nitrogen.
-
Extended Operational Service Life: Excellent mechanical strength and minimal dust formation significantly increase the lifespan of the adsorbent and protect downstream filters from clogging.
-
Optimized Operating Pressure: Designed for efficient performance at lower operating pressures, directly contributing to reduced energy consumption in air compressors.
-
Moisture Resistance: Possesses a robust structure resistant to moisture-induced degradation, ensuring stable and consistent performance over the long term.
4. Industrial Applications
-
Food & Beverage Industry: Modified Atmosphere Packaging (MAP) and nitrogen injection processes to extend the shelf life of perishable food products.
-
Electronics Industry: Providing an inert atmosphere for wave soldering and Surface Mount Technology (SMT) reflow processes to prevent unwanted oxidation.
-
Chemical & Petrochemical Industries: Blanketing storage tanks, inerting reactors, and facilitating the safe transfer of flammable materials.
-
Metallurgy & Heat Treatment: Processes such as carburizing, nitriding, and bright annealing of various metals.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This product is non-flammable; however, its dust may cause respiratory sensitization. The complete MSDS file is available upon request from Arnico support.
-
Storage Conditions: Store in tightly sealed containers in a dry, cool environment, away from moisture, oil, flammable gases, and direct sunlight. Exposure to rain must be strictly avoided.
-
Personal Protective Equipment (PPE): When charging or discharging PSA vessels, the use of an approved dust mask (such as N95) is recommended.
6. Quality Assurance & COA
Arnico provides all shipments of Carbon Molecular Sieve with a dedicated Certificate of Analysis (COA), which includes a nitrogen performance curve across various purity levels (from 99% to 99.999%). This ensures our clients achieve maximum efficiency from their PSA systems.
