high quality
Every column is rigorously tested

Full range of chromatographic columns

Reliable technical support

Years of accumulated rich experience in chromatographic analysis and technical team

quality assurance:

Use high-quality stainless steel tubing, glass tubing and chromatography packing to make a variety of high-efficiency packed chromatography columns

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

If on-column injection is used, there will be a 6CM space at the front of the column inlet.

To prevent the outflow of chromatographic packing, both ends of the column are blocked with silanized glass wool

If the column is filled with valve injection or non-on-column injection, the column inlet is filled

Various glass column configurations for gas chromatographs are available

The entrance of the 2mm inner diameter glass column tube is equipped with a slope to facilitate sample injection

Each column is fully conditioned and tested for rigorous quality evaluation





Precautions

Thank you for purchasing a chromatographic column produced by Haohan.

Every chromatographic column provided by Haohan has been aged. To ensure you get the best analytical separation effect, please aged for 1-2 hours before use. When aging, the carrier gas should be passed through for about 10 minutes. After the air in the column is completely replaced, the temperature is programmed to increase to the maximum operating temperature for aging.

To avoid contamination of the detector, do not connect the column to the detector during conditioning.

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

When installing a chromatographic column, the product number should face the operator, and the left side is the injection port of the chromatographic column (or see the logo).

When disassembling the column, bring the column temperature down to room temperature before turning off the carrier gas.
