Standard solutions
The ion chromatography is a technique that allows simultaneous determination of many kinds of ions at a high sensitivity. It is
used for environmental measurement related to wastewater, soil and atmosphere and in various fields, e.g. food quality control.
Products certified by JCSS
We have been accredited as a calibration organization (accredited calibration body) of pH standard solutions, metallic standard
solutions and ion standard solutions by the Minister of Economy, Trade and Industry and have commercialized standard
solutions conforming to Japan Calibration Service System (JCSS). Each bottle of the products certified by JCSS is provided
with a calibration certificate with JCSS logo mark which certifies the traceability to the national measurement standards.
