Cultural relics are non-renewable cultural resources, and every data interpretation in scientific archaeology may rewrite a chapter of history. Pure water may seem the most basic ""auxiliary material" in the lab, ", yet it is the underlying variable that safeguards relic security and analytical accuracy. The AiKe AK floor-standing pure-water system responds to the compound needs of cultural-relics scientific preservation in flow, water quality and site with a combination of "classified water supply, stable compliance, intelligent operation and maintenance, and silent compactness", and is essentially insuring the long-term data assets of archaeological research with a reliable domestic pure-water system.

I. Unit Profile: Guardians of Silk-Road Civilization

The Gansu Provincial Institute of Cultural Relics and Archaeology is a county-level public institution directly under the Gansu Provincial Cultural Relics Bureau, undertaking archaeological surveys, exploration and excavations of cultural relics resources throughout the province, as well as comprehensive research, publicity and promotion of archaeology and cultural-relics protection, and domestic and foreign academic exchanges. The institute has 14 internal institutions, among which the Scientific Archaeology Department, the Excavated Cultural Relics Protection Department and the Laboratory Archaeology Department constitute the core chain of cultural-relics scientific protection.

Relying on "the key scientific research base for bio-archaeology in cold and arid regions" of the State Administration of Cultural Heritage, the "key scientific research base for the protection of organic cultural relics excavated in arid environments" of the Gansu Provincial Cultural Relics Bureau, as well as the key laboratory of philosophy and social sciences of Gansu Province, the institute continuously promotes the normalized application of scientific and technological means such as dating technology, environmental archaeology, isotope analysis, ancient DNA and residue analysis in field archaeology. Projects such as Qingyang Nanzuo, Lixian Sijiaoping and Wuwei Tuyuhun royal clan tombs, and Zhangjiachuan Majiayuan have been selected as "Top 10 New Archaeological Discoveries in China" many times, and a total of more than 3,000 pieces (sets) of various cultural relics such as metal, textile, lacquer and wooden wares, and painted pottery have been repaired within five years.

II. The Proposition of Scientific Archaeology: Experimental Infrastructure that is Underestimated"": the Underestimated Experimental Infrastructure

When archaeology moves from "hand shovel" to "instrument", laboratory water becomes the key variable that determines the credibility of data.

First, the treatment of the relics themselves. Dechlorination and desalination of excavated metal artifacts, cleaning of textiles and lacquer-wood wares, and removal of soluble salts from painted pottery all require a large amount of low-ion and low-organic pure water, which must be produced and used on site to avoid secondary pollution from storage.

Second, support for precision analysis. Isotope analysis, residue analysis, ancient DNA extraction, ICP-MS/LC-MS and other trace detection are extremely sensitive to metal ions, TOC and anion content in water, and water-quality fluctuations are directly reflected as data drift.

Third, the dual constraints of flow and space. On-site extraction, laboratory cleaning and batch cleaning often proceed simultaneously, and water use shows the characteristics of "large flow + intermittent peaks", while the space, noise and drainage conditions of cultural-relics protection laboratories are usually limited.

Barreled distilled water or small desktop machines can hardly balance flow, water-quality stability and operation and maintenance cost, and the central water-supply-grade floor-standing pure-water system is a more suitable answer.

III. AiKe AK Floor-Standing Pure-Water System Solution

In response to the above needs, the AiKe AK series floor-standing system adopts a multi-stage progressive process of "pretreatment + reverse osmosis (RO) + deep purification (EDI/ultra-purification column) + dual-wavelength ultraviolet + ultrafiltration + terminal filtration":

• Zoned water supply, one machine for multiple uses. It simultaneously produces RO pure water (conductivity ≤5 μS/cm@25℃) and UP ultra-pure water (resistivity 18.25 MΩ·cm@25℃), respectively matching relic cleaning, vessel rinsing and trace analysis such as ICP-MS and ion chromatography, avoiding "high-quality water used for low-grade purposes"。

• Strict control of key indicators. TOC is as low as ppb level, heavy-metal ions, chloride ions and nitrate are controlled at sub-ppb level, and microorganisms are <≤1 cfu/ml, complying with GB/T 6682-2008 Grade 1 water, GB/T 33087-2016 and ASTM, CLSI, USP and other standards, meeting the acceptance requirements of CNAS laboratories.

• Floor-standing large flow. The water production capacity covers tens to hundreds of liters/hour, equipped with a fully enclosed vacuum sterile water storage tank and a built-in ultra-pure water circulation program, calmly coping with the centralized water intake at cleaning peaks.

• Intelligent operation and maintenance. Microcomputer control, three-channel online water-quality monitoring, consumable life warning, automatic RO membrane flushing, water leakage alarm and fault self-checking greatly reduce the pressure of full-time duty; the modular quick-connect structure enables filter replacement without tools.

• Silent and space-friendly. The operating noise is low and the body structure is compact, adapting to the limited space of relic restoration rooms and laboratories.

Together with laboratory wastewater treatment equipment, it can further form a closed loop of "pure-water preparation - use - waste-liquid treatment", responding to the increasingly strict environmental discharge requirements of cultural-relics protection units.
