High-performance liquid chromatography ultrapure water system

The high-performance liquid chromatography ultrapure water system removes ions, organic matter, and particles from water through multi-stage filtration and purification technologies, producing ultrapure water with a resistivity of 18.2 MΩ·cm. This equipment provides interference-free experimental water for liquid chromatographs, ensuring stable baseline conditions for mobile phases. It is widely used in pharmaceutical and environmental testing for reagent preparation and instrument cleaning.
Selection
Select to ensure a product water resistivity of ≥18.2 MΩ·cm and a total organic carbon content of ≤5 ppb. Match the capacity of the storage tank according to daily water consumption, and prioritize integrated systems with pre-treatment functions. Consider the replacement cycle and cost of consumables; quartz distillation units and UV sterilization modules can extend the lifespan of purification cartridges. Pay attention to the water quality requirements and instrument compatibility.
