Tianjiang and Waters Joint Laboratory


On October 25, 2017, the joint laboratory of “Tianjiang Pharmaceutical·Waters Chinese Herbal Extracts Quality Evaluation, Analysis and Testing” was officially inaugurated. Tianjiang attaches great importance to the use of various advanced modern technologies to control the whole process of producing Chinese herbal extracts, including raw materials testing, process and quality standards. By taking the lead in introducing liquid-phase and liquid-mass spectrometry technology in the industry, Tianjiang has made up for the shortcomings of using only one, the unprecise indicator in determining the constituents of its products in the past, and ushers in a new era of comprehensive and accurate Chinese herbal extracts.

Waters is a global leader in liquid-phase and liquid-mass spectrometry, LC/MS and information technology. It has developed a series of separation science, laboratory information management, mass spectrometry, and thermal analysis technologies, and collaborated with many universities and research institutes. It has the most advanced and complete set of practical solutions as well as numerous application experiences in the field of the making of Chinese herbal extracts. The joint laboratory means that Tianjiang's research of Chinese herbal extracts will be integrated with Waters' cutting-edge technologies, with research concentrated on solutions and equipment, furthering the research in Chinese herbal extracts quality control standards.
