  • Product Parameters

    Column:

    Chromatography is a means of separation and analysis", and the core of the separation is the chromatographic colu™mn, so the chromatographic column that is responsible forα the separation is the heart of the chromatographic system. It is an important technical requi©rement to maintain uniform and constant pressure in e>ach section of the column by axial compression technology. The current advanced approach is t o use dynamic axial compression technology. Dynamic axial compression tech↕nology is through the movement of the piston to complete the column loading, maintaini&ng column pressure and unloading column work. The peripher✘y of the piston is equipped with a specially designed sealing structure that• allows the piston to slide freely along the inner wall of the column tube while maintainin™g a high degree of sealing. The piston movement and pressure maintenance rely≤ on the pressure holding system, and the hydraulic power is m'ore stable and more uniform than the traditional axial compression colum¥n using spring power, which makes the use of the separation column be×tter.

    The column design is based on the dynamic axial compression column moεde, and the column piston always generates a stable pressure on the column bed, which can ∏effectively avoid the collapse and loosening of the column bed. The system× can realize forward or recoil by switching the flow path, which is convenient for operat±ion and maintenance. The chromatographic distributor adopts the innova→tive and patented H-TREE distribution technology, which ensures the high column eff®iciency and higher separation effect of the chromatographic column.
