Rapid water quality tester reaches international advanced level

After the scientist breaks a small glass tube in the water sample to be tested, the small glass tube rapidly absorbs water and then shows a color reaction. Then it is inserted into a small instrument, and the data extraction key is pressed to determine the concentration of the analyte in the water. The data is clearly displayed before the review experts. This is the scene at the appraisal meeting of the “ZW Multi-Parameter Field Tester and Water Quick Test Tube Method” held in Zhengzhou recently.

Experts of the project appraisal expert group, including Wang Erkang, academician of the Chinese Academy of Sciences, and Wei Fusheng, academician of the Chinese Academy of Engineering, agreed that the project simplifies cumbersome laboratory tests and has developed a multidisciplinary technology such as highly integrated colorimetric analysis, modern photovoltaics, and information processing. The new water quality on-site rapid test method with independent intellectual property rights provides a field test instrument that is widely applicable, simpler, intelligent, miniaturized, and portable for the construction of China's environmental safety emergency monitoring system, breaking the foreign technology and products. Monopoly, reaching the international advanced level.

The project leader, Bai Li, a research fellow at the Henan Academy of Sciences, told reporters of the “China Science Journal” that the project has undergone more than 10 years of research, mainly consisting of self-priming water quality rapid test tubes (color rendering system) and "Intelligent full-color tester" (detection system) consists of two core technologies, forming a unique rapid on-site water quality testing method and product system. In particular, the color system composed of 57 test tubes and the test system of the test system can be used to quickly determine a test object within minutes.

It is reported that they have applied for more than 50 national invention patents, obtained 28 patents, possessed state-level new products and national torch plan project certification; and in 2011 they were included in the national environmental protection emergency monitoring technical standards.

Li Shuhua, general manager of the Henan Academy of Sciences Zhengzhou Water Testing Technology Co., Ltd., said that the product of this project has technical advantages such as simple operation, strong anti-interference, stable and reliable data, and low secondary pollution, making it difficult to verify the speed and reliability of on-site water quality testing. Balanced problems can be better resolved, greatly improving the rapid response capability and emergency management level under emergency conditions. In the 2008 Wenchuan Earthquake Relief and subsequent Beijing's fight against "A stream", Yushu earthquake relief, Shanghai World Expo security and other major events, the project products have played a prominent role.

It is reported that during the implementation period of the project, direct economic benefits have been generated by nearly 20 million yuan, and the indirect benefits of replacing imported products and reducing disaster losses have reached several hundred million yuan.
