Kanto Chemical offer PrimepureTM series “High Purity Inorganic Compounds”, with ppb levelcertification for more than 30 species of trace level impurities. Historically, we have beendeveloping novel procedure of manufacturing / purifying for many kinds of inorganic compounds,
and also trace level analysis technique. PrimepureTM Series “High Purity Inorganic Compounds”
surely allows you reliable result of the work in the field of high performance electric materials,
functional materials, or so on.

Feature〇 High pure raw material
We have been manufacturing high purity acid and base for various fields.
As typified by UltrapurTM grade of acid and base from us are the high purity reagent chemical which
are guaranteed ppb level of impurities. As same as UltrapurTM grade reagents, high purity inorganic
compounds series PrimepureTM are used high purity raw material as well.
〇 Original manufacturing method (Original purification method)It’s difficult to produce high purity inorganic compounds from just using high purity raw material.
Kanto Chemical can manufacture high purity inorganic compounds because we use thosetechnology and experience which have been accumulating.
〇 Extreme trace analysis
In order to guarantee high purity reagent chemical, we are using extreme trace analysis
technology. We have been accumulating technologies which can guarantee so many kinds ofreagent chemicals through getting certified ISO/IEC 17025 accreditation.
We are performing extreme trace analysis of high purity inorganic compounds by catching up withdevelopment of analytical equipment.
〇 Homologous elemental impurity
Inorganic compounds may contain homologous elements as impurities. For example, sodium salts
may contain potassium as impurity. Although it’s difficult to remove those impurity, We achieve toreduce those impurity by our original technology.
