With the escalating trade war between China and the United States, many imported analytical instruments from the United States have also been included in the sanctions list. If users continue to purchase instruments produced in the United States, they will encounter significant price increases. In this context, Swiss company Wantong, together with Austrian company Antonpa and German company Sadolis, jointly held the "Water Quality Analysis Product Technology Exchange Conference" to introduce the advantages and applications of European analytical instruments to users in the water quality analysis industry, providing them with better choices.

This exchange meeting was held at the Sheraton Hotel in Jinan, Shandong Province, with nearly 50 users from more than 30 units participating. Li Zhibo, the product manager of ion chromatography from Switzerland's Wantong, introduced the application of ion chromatography in routine water quality analysis. Gong Yan, the product manager of automatic potentiometric titration, introduced the application of automatic potentiometric titration in water quality analysis. Yang Yuantian from Shandong region introduced the application of voltammetric polarography in water quality analysis. In addition, application engineers Hu Wei and Lu Kunjun from Antonpa, Austria, introduced microwave digestion equipment and photometric products respectively, while water system product manager Zhang Yanfen from Sartoris introduced the pure water machine series products. The exchange meeting lasted for a whole day, with a lively atmosphere and continuous applause on site. After the meeting, although everyone worked very hard, they all expressed that they had gained a lot from this exchange meeting and it was not a waste of this trip.

In water quality analysis, the Swiss Wantong Yinglan sample pretreatment technology is a very convenient and fast pretreatment technology, which includes more than ten sample pretreatment technologies such as Yinglan dialysis, Yinglan ultrafiltration, and Yinglan organic elimination. It can greatly reduce or even eliminate manual treatment, * reduce the workload of experimental personnel, and minimize the risk of sample contamination.

Blue ultrafiltration technology

Compared with manual filtration, the Swiss Wantong Blue ultrafiltration technology has the advantages of being faster and more economical. It combines the injection and filtration processes together, and a membrane with a pore size of 0.2 μ m can process more than 100 samples. For routine sample analysis, blue ultrafiltration technology is an ideal sample pretreatment method.

Blue dialysis technology

Blue dialysis technologyIt is a technique used to process complex matrix samples. This technology can not only remove particles from the sample, but also be used to remove colloids, oily components, and macromolecules. For samples containing proteins, they can be directly injected after treatment with indigo dialysis technology, avoiding complex and time-consuming manual processes such as sedimentation of proteins using Karry reagents.
