Tsingcarbo® ST Packed Column

Sizes can be customized, please contact sale@tsingcarbo.com

Tsingcarbo® ST packed columns are filled with Tsingcarbo® ST packing material independently developed by Suzhou Qingtan Nano Materials Co., Ltd. They serve as a domestic alternative to ShinCarbon ST packed columns and can effectively separate gases such as H₂, O₂, N₂, CO, CH₄, C₂H₆, C₂H₄, and C₂H₂.

Key Features

Strong Separation Capability: Tsingcarbo® ST packed columns can separate O₂/N₂ at 35°C.

Excellent Thermal Stability: They exhibit good stability at high temperatures, with a maximum operating temperature exceeding 300°C, making them suitable for high-temperature analysis.

Chemical Inertness: The packing material is carbon molecular sieve, which is chemically inert and resistant to corrosive gases and compounds such as acids and bases.

Long Lifespan: Due to the strong inertness of the carbon material, it is resistant to corrosion by acids, bases, and other substances, ensuring high stability and durability.

Application Fields

Environmental Monitoring: Used for detecting greenhouse gases and volatile organic compounds (VOCs) in the atmosphere.

Petrochemical Industry: Used for analyzing natural gas, refinery gas, and light hydrocarbon compounds.

Food Safety: Used for detecting residual gases in food packaging.

Pharmaceutical Industry: Used for analyzing residual solvents or gas components in pharmaceuticals.

Technical Parameters

Packing Material: Carbon molecular sieve.

Column Dimensions: Common column lengths range from 1 to 3 meters, with inner diameters of 2 to 4 millimeters.

Temperature Range: Typically from room temperature to 300°C, depending on application requirements.

Carrier Gas: Commonly used carrier gases include helium, nitrogen, or hydrogen.

Usage Precautions

Avoid Contamination: Moisture, particulate matter, or other impurities in the sample may affect column performance, so sample pretreatment is necessary.

Regular Maintenance: Depending on usage frequency and sample type, perform regular aging or regeneration of the chromatographic column.

Storage Conditions: When not in use, it is recommended to store the chromatographic column in a dry, cool environment with both ends sealed.
