The stable operation and data reliability of ion chromatography highly rely on systematic daily maintenance and timely fault diagnosis. Following the principle of "prevention first" can reduce downtime. 1、 Core daily maintenance points for mobile phase management: Ultra pure water (resistivity ≥ 18.2M Ω· cm) and high-grade reagents must be used. All solutions need to be filtered through 0.22 μ m or 0.45 μ m filter membranes and subjected to ultrasonic degassing. Check the amount of rinsing solution daily to avoid pump emptying. Pump system maintenance: Check daily whether the pump pressure is stable and record the baseline pressure. Regularly (such as weekly) exhaust the pump head and clean or replace consumables such as check valves and sealing rings according to the manual requirements. Flow path and column protection: always ensure
The core competitiveness of ion chromatography columns lies in the innovation of stationary phase materials and the optimization of separation mechanisms. Modern stationary phase research and development has broken through the limitations of traditional ion exchange resins, achieving dual improvements in separation efficiency and selectivity through functional group modification, nanostructure regulation, and monolithic column technology.
