Description
Technical Field
The utility model relates to a stainless steel self sealss gel purifying column device, mainly used food medicine environmental safety's gel purification technique, especially food environment detection's purification method. Through using the utility model discloses, can avoid user of service misoperation, solvent loss, the column effect descends.
Background
The stainless steel self-sealing gel column has a high separation effect on high molecular substances by a size exclusion principle, and is also widely used for separating small molecular compounds. In the aspect of food environment safety detection, gel purification is widely applied to removal of macromolecular substances such as grease, protein and pigment.
The conventional gel column is filled with glass, has poor compression resistance, is loose in filler and wastes a solvent. Once the system pressure is too high, there is a risk of glass breakage. The positive and negative direction of post can both move, if the installation of gel post direction is reversed, can exert an influence to the post, reduces gel post life. Meanwhile, the gel column has poor sealing effect, particularly when the mobile phase is dichloromethane and other solvents, the gel column is easy to volatilize, and if the gel column is not used for a long time, the filler is dried, the structure collapses and the column effect is influenced. Moreover, when the joint is unscrewed during replacement of the gel column, the mobile phase leaks from the gel column, which increases the difficulty of replacement.
For example, a container used for gel purification is usually a glass-packed gel column. After the practical experiment is finished, if the gel column is not used for a long time, the gel column needs to be detached and sealed, liquid leakage is easy to occur in the detaching process, and the operation is difficult. And the mobile phase needs to be filled into the gel column again at intervals, otherwise, the gel column can generate the conditions that the solvent is volatilized, and the filling material is dried and collapsed. If the column is not oriented correctly when it is reused, the flow will back-wash the gel column, which will affect the gel column lifetime. Since the packing of gel columns is expensive, the packing must be replaced if the column efficiency is reduced due to the collapse of the packing, resulting in economic losses.
The market also has stainless steel post, but except solving the resistance to compression problem, other for example can not one-way circulation liquid, do not have self-sealing function, and the backward flow and the weeping condition still exist easily appearing in the flow compatibility, all can influence gel post life.
