The 29th Qingdao Analytical Testing Society Annual Conference – Academic Symposium Series & International Scientific Instruments and Laboratory Equipment Exhibition

In April 2026, the 29th Qingdao Analytical Testing Society Annual Conference – Academic Symposium Series & International Scientific Instruments and Laboratory Equipment Exhibition was grandly held at the Qingdao International Conference Center. As a leading enterprise in the ion chromatography field, Qingdao Puren Instruments Co., Ltd. made a striking appearance with a range of innovative products and cutting-edge solutions, engaging with industry peers to discuss new trends in intelligent detection and demonstrating the formidable strength of domestically produced high-end analytical instruments.


Exquisite Exhibits Demonstrating Technological Excellence


At the exhibition site, Puren Instruments showcased a selection of representative products centered on the core themes of "intelligent, precise, and efficient." Among them, the intelligent online ion chromatograph with concentration pre-judgment capability became a center of attention. Equipped with a self-developed concentration detection pre-dilution module, this device automatically adjusts the dilution ratio based on sample concentration, ensuring thorough mixing of the sample and diluent, significantly improving detection accuracy and resolving the traditional pain point of manual concentration pre-judgment.


In addition, the PIC-70 portable ion chromatograph, featuring a "three-proof" (explosion-proof, drop-proof, and waterproof) design, dual AC/DC power supply, and an ultra-long battery life of 36 hours, became the "star product" for on-site mobile detection scenarios. As the world's only dual-system portable ion chromatograph, its lightweight design and real-time monitoring capabilities make it widely applicable for environmental emergency monitoring, vehicle-mounted inspection, and more. The PIC-80 ion chromatograph, with its integrated structure and 4.5-inch touchscreen, enables real-time data synchronization and massive data storage. Paired with a 13-position autosampler, it can automatically prepare standard solutions and dilute samples, truly achieving "unattended" fully automated detection.


Technological Accumulation Laying a Solid Foundation for Growth


Since its establishment in 2002, Puren Instruments has remained deeply committed to the ion chromatography field. The company participated in drafting the national ion chromatograph metrological verification regulation JJG832-2014 and holds over 50 patented technologies. Certified under ISO-9001, the company has been recognized as a "National High-Tech Enterprise" and a "Shandong Provincial Specialized and Sophisticated SME." Its products have been selected as "Excellent Domestic Instruments" and were deployed aboard the "Xuelong" icebreaker for scientific expeditions to Antarctica, withstanding extreme environmental conditions with outstanding performance.


The core accessories showcased at this exhibition, including eluent generators and autosamplers, are all 100% independently developed, breaking foreign technological monopolies. Among them, the dual-system eluent generator produces high-purity eluent in real time, completely eliminating manual preparation errors and ensuring stable detection results, making it a "standard" product in many laboratories.


Industry Empowerment Building a Detection Ecosystem


During the academic exchange sessions, Puren Instruments' technical team shared their latest research findings on "Applications of Ion Chromatography in Environmental, Food, and Occupational Health Sectors." From perchlorate detection in water to citric acid analysis in fruits and vegetables, from workplace ethanolamine monitoring to ionic residue detection in clean gloves, Puren Instruments' solutions now cover 127 fields, including environmental protection, quality inspection, disease control, and petrochemicals, serving over 10,000 customers.During the exhibition, the company reached cooperation intentions with multiple universities and third-party testing institutions to jointly promote the expansion of ion chromatography applications in emerging fields. As the technical director of Puren Instruments stated: "We provide not just instruments, but a full-process service from method development to data interpretation, making detection more efficient and more reliable."


Conclusion: Innovating for the Future


This annual conference was not only a concentrated showcase of Puren Instruments' technological strength but also a microcosm of the development of the domestic ion chromatography industry. From laboratory to online monitoring, from routine testing to emergency analysis, Puren Instruments has always upheld the mission of "precise detection, safeguarding safety," driving domestic instruments from "following" to "leading." Looking ahead, the company will continue to deepen its ion chromatography technology, focusing on intelligence and automation to deliver even more valuable detection solutions to users worldwide, enabling "Qingdao-made" scientific instruments to shine on the global stage.
