In the public health defense system, the Center for Disease Control and Prevention (CDC) is always at the forefront of responding to sudden epidemics and monitoring health hazard factors. In this invisible battle, accurate experimental data is the only basis for formulating prevention and control strategies. As the 'brain' of provincial health and epidemic prevention, the laboratory of Sichuan Provincial Center for Disease Control and Prevention introduced AiKe AK floor-standing large-flow pure-water machine, building a solid and reliable water-quality guarantee system for the province's public health testing work.

I. Unit Introduction and Background of Water-Equipment Application

Sichuan Provincial Center for Disease Control and Prevention is the authoritative institution for disease control and prevention, health monitoring and testing, and scientific research training guidance throughout the province. Its physical and chemical testing institute, microbiological testing institute and other departments undertake heavy tasks such as infectious pathogen detection, food risk monitoring, and drinking-water and environmental pollutant analysis for the whole province.

The testing work of the CDC is characterized by large sample volume, complex testing indicators and extremely high precision requirements. Especially when using top analytical equipment such as liquid chromatography-mass spectrometry (LC-MS) and inductively coupled plasma mass spectrometry (ICP-MS) for pesticide residue trace analysis, heavy-metal detection and virus nucleic-acid extraction, there are extremely low thresholds for trace ions, organic matter and bacterial endotoxins in experimental water. Sichuan has a developed water system, but the source water is affected by the alternation of flood and dry seasons, with large fluctuations in turbidity and mineral content. The original small and medium-sized water-treatment equipment often has insufficient water production and fast water-quality decay when facing large-batch sample testing, and it is difficult to meet the high-intensity and multi-scenario water needs of the provincial CDC. For this reason, after strict selection, Sichuan Provincial CDC introduced AiKe AK floor-standing large-flow pure-water machine.

II. The Solution Brought by AiKe Pure-Water Machine

In response to the characteristics of large flow, high standards and raw-water fluctuations of Sichuan Provincial CDC, AiKe AK floor-standing pure-water machine provides an efficient and stable all-round solution:

1. Large-flow water production and floor-standing compact design
As a provincial CDC, the daily cleaning of utensils and preparation of reagents consume a lot. The AiKe AK series adopts an integrated floor-standing design with a built-in large-capacity sterile water tank, realizing continuous and stable supply of large-flow pure water. Its optimized internal structure not only saves the precious floor space of the laboratory, but also meets the high-frequency demand of multiple terminals taking water at the same time.

2. Strengthened pretreatment adapted to raw-water fluctuations
In view of the seasonal sediment and hardness changes of source water in Sichuan, the AK series is equipped with a multi-stage deep pretreatment module. The synergy of high-capacity filtration and softening materials effectively resists the impact of raw-water quality, protects the reverse-osmosis membrane from the source, and greatly reduces the maintenance frequency and consumable cost of the equipment.

3. Two-stage RO and ultimate terminal ultrafiltration
The equipment adopts two-stage reverse osmosis (RO) technology combined with terminal ultrafiltration (UF) module, which can not only completely strip cations and anions in water, but also effectively remove bacteria and endotoxins. The produced water quality far exceeds the Grade 1 water specification of China's National Analytical Laboratory Water Standard (GB/T 6682-2008), ensuring an interference-free environment for trace analysis and molecular biology experiments.

III. Usage Scenarios of AiKe Pure-Water Machine

In the daily operation of Sichuan Provincial CDC, AiKe AK floor-standing pure-water machine deeply participates in the testing scenarios of multiple key fields:

• Food and water-safety risk monitoring: when detecting pesticide residues and illegal additives in food and heavy metals (such as lead, cadmium and arsenic) in drinking water, ultra-pure water is used for instrument mobile-phase preparation and sample constant volume; the extremely low ion background value ensures the high sensitivity and accuracy of mass-spectrometry analysis.

• Infectious pathogen detection: when responding to sudden infectious diseases such as influenza and COVID-19, ultra-pure water is used for nucleic-acid extraction reagent preparation and PCR reaction system construction. The nuclease-free and pyrogen-free water quality effectively eliminates false positives or inhibition effects, guaranteeing the absolute reliability of test results.

• Toxicology and biochemical experiments: in cell culture and toxicity evaluation experiments, the high-quality pure water provided by the pure-water system is used for culture medium preparation and final cleaning of experimental vessels, eliminating the interference of external impurities.
