  • Product Parameters

    Column:

    Chromatography is a means of separation and analysis, and the γcore of the separation is the chromatographic column, so the chromatographic column t↓hat is responsible for the separation is the heart of 'the chromatographic system. It is an important technical requirement to maintain uniform and co∞nstant pressure in each section of the column by axial compression tec↔hnology. The current advanced approach is to use dynamic axial ♥compression technology. Dynamic axial compression technology is through the movement♠ of the piston to complete the column loading, maintai↓ning column pressure and unloading column work. The peri§phery of the piston is equipped with a specially designed sealing stru≈cture that allows the piston to slide freely along the inner walβl of the column tube while maintaining a high degree of seali"ng. The piston movement and pressure maintenance rely on the pres<sure holding system, and the hydraulic power is more stable and more ≠uniform than the traditional axial compression column using s₽pring power, which makes the use of the separation column better.

    The column design is based on the dynamic axial compres≈sion column mode, and the column piston always generates a st&able pressure on the column bed, which can effectively avoid the collapse and lαoosening of the column bed. The system can realize forward or recoil b₩y switching the flow path, which is convenient for operatiφon and maintenance. The chromatographic distributor adopts the innovative✘ and patented H-TREE distribution technology, which ensures thγe high column efficiency and higher separation effect of the chromatographic column.
