In modern ecological-environment monitoring, the accuracy of water-quality analysis data is directly tied to the scientific rigor of environmental decisions. Throughout the analysis chain, experimental water—the most basic reagent—has quality that is the cornerstone of data reliability. The Jiangxi Yichun Shanggao Ecology & Environment Bureau, as a front-line local environmental-protection unit, has its laboratory undertaking multi-element monitoring of regional water quality, soil, and more. Today, we focus on the AiKe (Exceed) series ultrapure water machine introduced into the bureau's laboratory, exploring its stable performance and industry value over eight years of operation.

I. Unit Introduction and Background of Water-Equipment Application

The Shanggao Ecology & Environment Bureau of Yichun City is the government functional department responsible for ecological-environment protection and supervision within Shanggao County. Its subordinate environmental-monitoring laboratory routinely performs high-frequency sampling and physical-chemical analysis of regional surface water, industrial wastewater, drinking-water sources, and atmospheric precipitation. As national environmental standards grow stricter, monitoring indicators are more granular, and high-level analysis items such as heavy-metal trace analysis and volatile-organic-compound detection are becoming routine.

Against this backdrop, ordinary distilled or general deionized water can no longer meet the stringent requirements of instrumental analysis. Precision instruments such as inductively coupled plasma mass spectrometry (ICP-MS) and high-performance liquid chromatography (HPLC) have extremely low thresholds for trace ions, organic matter, and microbial content in water. Therefore, about eight years ago (around 2018), after rigorous market research and model comparison, the Shanggao Ecology & Environment Bureau ultimately decided to introduce the AiKe Exceed series ultrapure water machine, aiming to eliminate water-quality variables' interference with experimental data at the source.

II. The Solution Brought by the AiKe Exceed Ultrapure Water Machine

Over eight years, the AiKe Exceed series ultrapure water machine has provided the Shanggao Ecology & Environment Bureau laboratory with a complete and reliable pure-water solution, mainly reflected in the following aspects:

1. Dual water-quality assurance, meeting multi-dimensional needs
The AiKe Exceed series features dual-path output of pure water and ultrapure water. Pure water (RO water) meets routine glassware cleaning, buffer preparation, and autoclave needs; ultrapure water (UP water) maintains stable resistivity at 18.2 MΩ·cm@25℃, perfectly matching high-precision needs such as trace heavy-metal analysis and ion chromatography—one machine solving all laboratory water scenarios.

2. Core purification technology, ensuring ultimate purity
The equipment adopts a multi-stage purification process including deep pretreatment, reverse osmosis (RO), ion exchange, and terminal ultrafiltration. Targeting the municipal tap-water characteristics of the Shanggao area, AiKe equipment, through a scientific pretreatment module, effectively extends RO-membrane service life, while high-quality ion-exchange resin reduces ion content in ultrapure water to the ppt level.

3. Intelligent monitoring and long-term stability
For environmental-monitoring laboratories, data traceability is crucial. The AiKe Exceed series is equipped with an intelligent LCD that monitors and displays water conductivity/resistivity, water temperature, and consumable life in real time. Eight years of long-term operation, thanks to its stable system-architecture design and antibacterial piping materials, effectively reduces water-quality fluctuation risk and equipment failure rate during prolonged operation.

III. Usage Scenarios of the AiKe Exceed Ultrapure Water Machine

During its eight-year service period, the AiKe Exceed ultrapure water machine has been deeply integrated into the various daily tasks of the Shanggao Ecology & Environment Bureau laboratory:

• Trace-metal analysis water: When using atomic absorption spectrophotometry or ICP-MS to detect heavy metals such as lead, cadmium, mercury, and arsenic in water, ultrapure water is used to prepare standard-curve solutions, dilute samples, and rinse instrument injection. The extremely low background of ultrapure water ensures accuracy of trace detection.

• Routine physical-chemical analysis water: When testing routine water-quality indicators such as chemical oxygen demand (COD), ammonia nitrogen, and total phosphorus, the RO water provided by the pure-water system is used for reagent preparation and colorimetric-tube cleaning, preventing introduction of external impurities and lowering blank values.

• Microbial testing and final labware rinse: When testing water-quality coliform bacteria and other microbiological indicators, labware cleanliness directly determines success. Ultrapure water is used for final labware rinsing, effectively avoiding false-positive interference from trace organic matter or bacterial residue on culture results.

IV. Usage Precautions and Recommendations

Although the AiKe Exceed series is highly durable, maintaining efficient operation for eight years or longer requires routine maintenance and standardized operation. For laboratory management, the following precautions and recommendations are proposed:

1. Periodic consumable replacement must not be ignored: Pure-water machine consumables (such as PP-cotton filters, activated carbon, RO membranes, ultra-purification columns) have fixed adsorption capacity. Even if the equipment runs normally on the surface, consumables must be replaced strictly according to water-quality monitoring data and instrument-indicated lifespan; avoid 'overdue service' that silently degrades water quality.

2. Pay attention to periodic cleaning of the storage tank: After long-term use, a biofilm may form inside the pure-water tank due to trace bacterial growth. It is recommended to thoroughly clean and disinfect the storage tank every six months to a year to ensure stored-water quality.

3. Standardized restart after long holiday shutdown: If shutdown occurs during long holidays such as Spring Festival, the RO membrane is prone to drying out or bacterial growth. When restarting, first perform system flushing, discharge the initial produced water, and re-test all water-quality indicators; only after passing should it be used for precision experiments.

4. Establish a complete water-usage archive: It is recommended that laboratory managers regularly record the pure-water machine's intake water quality, production volume, and various operating parameters; this not only monitors current water quality but also provides data support for preventive maintenance.

Eight years is a severe test for a high-load laboratory device. The AiKe Exceed series ultrapure water machine in the Jiangxi Yichun Shanggao Ecology & Environment Bureau laboratory has delivered a satisfactory answer with eight years of stable operation. It not only provides solid assurance for the accuracy and authority of the bureau's environmental-monitoring data, but also confirms with its actual performance the excellent quality and reliability of high-quality domestic laboratory equipment. In the future, as ecological-environment monitoring deepens, such stable, intelligent, and durable basic experimental equipment will surely play an even more important role on the road to protecting green mountains and clear waters.
