Something about Lanthanum Tungsten Electrode by the Material of Lanthanum Tungsten Electrode Preparation – III

“Something about Lanthanum Tungsten Electrode by the Material of Lanthanum Tungsten Electrode Preparation – II” is mainly talked about the index of lanthanum acetate in chemically pure, analytical reagent and technicalgrade, and this article will describe the meaning and expansion of lanthanum acetate index in the table.

By purity, chemical raw materials can be divided into technicalgrade and reagentgrade (chemically pure, analytical reagent, laboratory pure and superiorgrade pure).
The purity of technicalgrade is very low and is just suitable in laboratory with lower requirements, such as, washing, dissolving or as raw materials in production.

Chemically pure (chemical pure reagent), abbreviated as CP --- third, blue label, it is a chemical reagent purity specifications; its main component content is high and its purity is also higher, but there is still a small amount of interference impurities; it may be used in synthesis experiments with a higher requirement and analysis experiments with less requirement.
Analytical reagent (AR) --- second, red label; its primary component content is higher and purity is also higher, impurity content is very low; it can be used in chemical experiments and industry analysis.
