Each column is rigorously tested

Full range of columns

Reliable technical support

Years of accumulated chromatographic analysis experience and technical team


High-quality stainless steel tubes, glass tubes and chromatographic packings for a variety of highly efficient packed columns



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

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

In order to prevent the elution of the chromatographic packing, both ends of the column are sealed with silanized glass wool.

If a valve injection or non-column injection column is used, the column inlet is filled

Glass column configuration for a wide range of gas chromatographs

2mm inner diameter glass column tube has a bevel at the entrance to facilitate injection

Each column is fully aging and rigorously evaluated

Precautions

Thank you for purchasing the column produced by Haohao.

Every column provided by Haohao is aging. To ensure the analytical separation you get, please aging for 1-2 hours before use. When aging, the carrier gas should be passed for about 10 minutes. After the air in the column is replaced, the temperature is raised to the high temperature of the Zui.

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

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 column. The carrier gas must be further deoxidized by a deoxidizing tube (it is recommended that the oxygen content of the carrier gas used should not exceed 1 ppm)

When installing the column, the product grade should be facing the operator and the left side is the column inlet (or see the label).

When disassembling the column, first lower the temperature of the column to room temperature, then turn off the carrier gas.
