Description
Technical field
The utility model relates to chromatography column field more particularly to a kind of chromatography columns with seal assembly.
Background technique
Chromatography column can be used for during chemical production technology to sample carry out purification and to contained by sample not
Analysis detection is carried out with component, is separated each component according to the physical qualitative difference of each component in sample.
But the component contained in some samples is more, and the physical property difference between various ingredients is little, only makes
It is difficult to separate each component in sample with a chromatography column, therefore, it is necessary to use different chromatographic columns and process
Different processes can just separate the little each component of physical property difference in sample.
Sample can successively be passed through different chromatographic column and technique by technician at present, and each component in sample is separated
Come, but such method increases treatment process, so that the process of separation sample complicates；And during chemical production technology,
One procedure of every increase, it will so that the content of each component of sample causes damages.
Therefore, 205269122 U of Chinese utility model patent CN discloses a kind of combined type chromatography column, the combination
