The 18-year continuous service of this AiKe Exceed floor-standing ultrapure water machine at the Chinese Academy of Sciences Qinghai Institute of Salt Lakes reflects both the hardware quality and system-design strength of the equipment, and shows that laboratory pure-water equipment selection for scientific research must consider not only initial water quality but also environmental adaptability, long-term reliability, and supporting O&M services.
For geological-mineral, salt-lake-chemical, and inorganic-analysis research labs, ultrapure water is not ordinary auxiliary equipment but an important prerequisite for experimental-data reliability. Suitable equipment plus standardized O&M can continuously output qualified experimental water, safeguarding major research projects.

💧 Equipment Water Quality: RO Pure Water + UP Ultrapure Water
The Chinese Academy of Sciences Qinghai Institute of Salt Lakes is a national-level research institute in China dedicated to comprehensive salt-lake resource research, with deep involvement in salt-lake geology, brine chemistry, strategic-element extraction, salt-lake new-material R&D, and salt-lake eco-environment monitoring. It undertakes basic research and industrialization technology for lithium, potassium, magnesium, boron, and other salt-lake resources. The institute has multiple key laboratories and public analysis platforms, equipped with ICP-MS, atomic absorption, and liquid chromatography, conducting large volumes of brine sample testing, inorganic trace-element analysis, reagent preparation, and material synthesis.
Salt-lake sample matrices are complex; brine itself contains high concentrations of salt impurities, and trace-element detection imposes strict requirements on experimental water. Residual ions, organics, and particles in water directly interfere with instrument readings, causing data deviation or even experiment failure; Grade-I ultrapure water is the basic condition for ensuring authentic and reliable scientific results. Meanwhile, the Qinghai plateau has large day-night temperature swings and obvious raw-water fluctuations, imposing higher standards on the equipment's environmental adaptability and long-term stability—the equipment must withstand long-term high-load continuous water production and meet the simultaneous demand of multiple research groups.
This Exceed floor-standing ultrapure water machine, in service for 18 years, provides a complete water-production solution for the institute's research-water pain points. Using tap water as feed, it simultaneously produces pure water and 18.25MΩ·cm ultrapure water; TOC, heavy-metal ions, and microorganisms meet the GB/T 6682 Grade-I water standard, suitable for various high-end analysis experiments in salt-lake research.
The equipment adopts a multi-channel real-time water-quality monitoring module to intuitively view core parameters such as resistivity and TOC, allowing experimenters to confirm output quality at any time; the system has built-in auto-flush, water-shortage protection, and full-water shutdown, reducing operational risks from plateau pressure fluctuations and manual duty burden. The floor-standing large-output design supports simultaneous intake by multiple analyzers, meeting concentrated water demand of multiple research groups. In May 2026, AiKe's technical team went on-site for special deep maintenance; after inspection, all water-production indicators remained up to standard, continuing to output stable water for research. After 18 years of continuous use in the plateau environment, the durability of the equipment's hardware materials and system architecture is fully verified.
Brine and mineral sample pretreatment: dilution, digestion, and blank-control preparation of salt-lake brine and mineral samples, avoiding interference from foreign ions in trace lithium, potassium, magnesium detection.
Precision-instrument supporting water: instrument rinsing and mobile-phase preparation for ICP-MS, atomic absorption, liquid chromatography, etc., reducing instrument contamination and extending instrument life.
Chemical experiments and reagent preparation: preparation of standard solutions, buffer solutions, and various inorganic reagents, meeting salt-lake chemistry and inorganic-synthesis experiments.
Labware cleaning and research auxiliary water: fine rinsing of experimental containers, routine physical-chemical experiments, distinguishing pure-water and ultrapure-water outlets, taking as needed to save consumable cost.
