Application: GB 16212-1996 Hygienic standard for nitroglycerin in the air of workshop
OV-17/Shim玻璃柱 测试谱图:
Each column is rigorously tested
Full range of columns
Reliable technical support
Years of accumulated chromatographic analysis experience and technical team
Quality assurance:
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 co
nfiguration 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 e
valuated
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 a
bout 10 minutes. After the air in the column is replaced, the temperature is raised to the high temperature of the Zui.
To avoid co
ntamination of the detector, do not co
nnect 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 statio
nary phase in the column. The carrier gas must be further deoxidized by a deoxidizing tube (it is recommended that the oxygen co
ntent of the carrier gas used should not exceed 1 ppm)
When installing the column, the product grade should be facing the operator.
