Ion Chromatography Instrument

As a new business model in the ion chromatography instrument market, our company has been committed to providing users with faster and higher quality instruments to ensure the construction and operation of laboratories. Always adhere to customer-centric approach and serve customers with testing needs. Good value for money, quick response, and comprehensive service.

The new generation ion chromatograph adopts a 12.1-inch flat industrial computer integrated design (users do not need to equip a computer), which displays the instrument's operating parameters and status in real time; One click start of electric valve injection, one click completion of instrument on/off, maintenance and other operations, one click access to instrument operation tutorials, convenient and fast.

The core components of ion chromatography are independently developed and have controllable intellectual property rights. Adopting an integrated design, it integrates the ion chromatography host, eluent generator, industrial computer, and chromatography workstation into one, with a compact structure and the shortest flow path, which greatly improves the peak expansion caused by the flow path. Integrated constant temperature box: The chromatographic column, suppressor, conductivity cell, and amplification circuit are all in the same constant temperature system, which improves the temperature drift and baseline noise of the conductivity detector. Built in multiple leak and water shortage alarms for comprehensive safety monitoring. The various components controlled by PLC are unified into a centralized software control system on the computer display screen, which is easy to operate and controlled by the mouse.
