With the increasing global environmental pollution, stringent testing of water quality (drinking water, discharge water) and foods has gradually become important. A new type of analytical instrument that automatically and continuously detects the anions, cations, and heavy metal ions in water was born. This is the first online ion chromatogram instrument developed by Qingdao Pren Instrument Co., Ltd. through unremitting efforts and lasted three years. -Online online ion chromatography, which fills the gaps in the current domestic online ion chromatograph, is of great significance to the development of the online inspection industry.
The technical indicators of on-line ion chromatograph developed by Qingdao Puren Instrument Co., Ltd. have passed the national verification and obtained a manufacturing license (CMC), which can be mass produced and marketed. As evaluated by national science and technology experts, this product has reached the advanced level of similar foreign products and is the only domestic manufacturer that can produce on-line ion chromatograph. At the same time, the product was also awarded the "Excellent New Product of Scientific Instruments Industry" award by Instrument Information Network.
The PIC-online on-line ion chromatograph developed by Qingdao Puren Instrument Co., Ltd. can be widely used in continuous detection of the environment, continuous detection of the production process, and other fields. This product performs on-line detection of ion chromatography for the on-line detection of ion chromatography. The method and the detection technology, on-line automatic processing of chromatographic data, product detection capability and detection accuracy, etc., are integrated innovations, and their technological innovations are mainly reflected in: 1. Designed an online detection process of ion chromatography, and Using embedded systems, three-channel parallel automatic detection is realized. 2. The on-line detection technology and data automatic processing technology using the conductance method can automatically detect the anions F-, Cl-, NO2-, PO43-, Br-, NO3-, SO42- and cations Li, Na, NH4, and K at the same time. Ca2, Mg2. 3, innovatively proposed the detection method of mobile voltammetry, and realized the online detection of heavy metal ions Cu2, Zn2, Pb2, Cd2.
Products can be widely used in the field of environmental protection and production process quality monitoring, etc., breaking the monopoly of foreign manufacturers in China, saving the country a lot of foreign exchange and funds, in the nuclear industry and other important industrial chain, to ensure the safety of important industry information.
In 2014, experts from the Ministry of Industry, Science and Technology, and Ministry of Environmental Protection reviewed and selected 146 major equipment from more than 3,000 projects. The “In-Line Three-Channel Analyzer of Anions and Heavy Metals in PM2.5†and “On-Line Automated Analyzer of Water Quality Based on Ion Chromatography†both applied by Qingdao Puren Instrument Co., Ltd. were selected as “National Environmental Protection Technologies Encouraged for Developmentâ€. Equipment Catalog (2014 Edition), and become the supporting unit for both projects.
