Ion chromatography rinse bottle

Ion chromatography rinse bottleIt is a specialized container used for storing and transporting eluent (mobile phase) in ion chromatography analysis. Its function is to ensure that the eluent maintains stable composition during high-pressure pump transportation, avoiding external environmental interference, thereby ensuring chromatographic separation efficiency and analytical reproducibility;

Ion chromatography rinse bottleCore design features:

1. Pressure resistant sealing structure

Adopting a thick walled design (such as polypropylene material with a wall thickness of ≥ 3mm), it can withstand pressures of 0.2-0.3MPa to prevent liquid leakage or bottle deformation;

The interface is tightly sealed and equipped with double-layer sealing rings or chemical resistant gaskets, suitable for the suction needs of high-pressure pumps;

2. Nitrogen pressurization system

Inject nitrogen through the bottle cap to maintain a positive pressure environment inside the bottle, avoiding contact between the rinsing solution and air (such as CO dissolution affecting the composition of the hydroxide system rinsing solution), and reducing the generation of bubbles during pump suction;

Some bottle caps are designed with multi-channel interfaces, supporting simultaneous connection of rinse solution tubes, nitrogen tubes, and exhaust channels.

Material and Capacity Specifications:

1. Material selection

-Polypropylene (PP): resistant to acid and alkali corrosion, suitable for conventional washing solutions (such as carbonate and methane sulfonic acid systems);

-Glass: high chemical inertness, suitable for strong corrosive or high-purity rinsing solutions, but requires explosion-proof protection devices;

-High temperature resistant material: Some products can withstand high temperature sterilization (such as high-pressure sterilization treatment);
