The "IA-300" is an ion analyzer that allows for easy ion analysis by simply injecting a sample and lowering a lever. It packages the functions of ion chromatography (such as the pump and printer) into one unit, enabling you to know the concentration of target ions just by injecting the sample into the device. The analysis and calculations of measurement data are performed automatically by the device itself. Compared to ion chromatographs that process data on a computer, this significantly reduces processing time. The measurement results can be printed from the built-in printer. 【Features】 ■ Set measurement conditions with mode selection Simultaneous measurement of 6 cation items or 7 anion items Anions: F-, Cl-, NO2-, Br-, NO3-, PO4-, SO42- Cations: Li+, Na+, NH4+, K+, Mg2+, Ca2+ ■ Automatic processing of analysis and calculations ■ Suppressor method also adopted for anion measurement ■ Realization of labor-saving through automatic measurement of multiple samples ■ Easy maintenance *For more details, please refer to the PDF document or feel free to contact us.

The "ICA-7000" is an ion chromatograph that integrates all units, including the detector, pump, display section, operation section, and column thermostat, into a single unit. It can accommodate two pumps for the suppressor removal solution. The column is stored horizontally, improving maintenance accessibility. By simply installing dedicated software, all operations can be performed from a PC. 【Features】 ■ All-in-one, compact design ■ Same size even for a 2-channel system ■ Excellent expandability due to modular equipment configuration ■ Device control and data processing via USB communication ■ Added low range for high-sensitivity analysis *For more details, please refer to the PDF document or feel free to contact us.
