  • Product Parameters

    Column:

    Chromatography is a means of separation and analysis, and the core of the separa♣tion is the chromatographic column, so the chromatographic column t₹hat is responsible for the separation is the heart of the chromatographic sys÷tem. It is an important technical requirement to maintain uniform and constant pressu§re in each section of the column by axial compression techn ology. The current advanced approach is to use dynam₩ic axial compression technology. Dynamic axial compression technolo‌gy is through the movement of the piston to complete the column loading, maintaining •column pressure and unloading column work. The periphery of εthe 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 maintaining a high degree of sealing. The piston movement and pressure maintenance re≤ly on the pressure holding system, and the hydraulic power is more st↓able and more uniform than the traditional axial compression column using ♠spring power, which makes the use of the separation column better.

    The column design is based on the dynamic axial compression column mode•, and the column piston always generates a stable pressure on the column bed, which can πeffectively avoid the collapse and loosening of the column bed. The system ca"n realize forward or recoil by switching the flow path, which is convenient for oper<ation and maintenance. The chromatographic distributor adopts the innovative and patented H-TREE di©stribution technology, which ensures the high column ₽efficiency and higher separation effect of the chromatographic column.
