This standard specifies the requirements, test methods, inspection rules, marking, packaging, transportation, storage, safety, etc. for industrial acetic anhydride. This standard is applicable to acetic anhydride produced by acetic acid cracking method or acetaldehyde oxidation method. This product is mainly used for the production of acetate fiber, pharmaceuticals, dyes, fragrances, films, and other products.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd., developed and produced《Apison graphitized carbon black column for measuring acetic anhydride 》High column efficiency and good separation. Installed and used on Agilent, Shimadzu, Thermo Fisher, Varian, Brooke, and PE, the separation of acetic anhydride and impurities is excellent, with satisfactory results.

Various packed chromatography columns are made using stainless steel tubes, glass tubes, and chromatographic fillers

If you need to use stainless steel filter mesh as the plug at both ends of the column, please indicate it when ordering

If a column is used for sampling, there will be a space of 6CM at the front end of the column entrance,

To prevent the chromatographic packing from flowing out, both ends of the column are sealed with silanized glass wool

If a chromatographic column with valve injection or non column injection is used, the inlet of the column is filled

Can provide glass column configurations for various models of gas chromatographs

The inlet of the 2mm inner diameter glass column tube is equipped with a sloping surface for sample injection

Each chromatographic column undergoes thorough aging and rigorous quality evaluation testing

Precautions

Thank you for purchasing the chromatography column produced by Haohan

Each chromatographic column provided by Haohan has been aged, and for the analysis and separation effect you have obtained, please age it for another 1-2 hours before use. When aging, the carrier gas should be introduced for about 10 minutes first, and after the air inside the column is completely replaced, the temperature should be raised to the operating temperature using a program for aging.

To avoid contamination of the detector, please do not connect the chromatography column to the detector during aging.

When the temperature of the column box is higher than room temperature, a small amount of oxygen in the carrier gas will damage the stationary phase inside the chromatographic column. The carrier gas must be further deoxygenated using a deoxygenation tube (it is recommended that the oxygen content in the carrier gas used should not exceed 1PPm)

When installing the chromatography column, the product brand should face the operator, with the injection port (or see identification) on the left side of the column.

When disassembling the chromatographic column, first lower the column temperature to room temperature, and then turn off the carrier gas
