What is the difference between chemical pure and pure analysis of kaolin?
Analysis of pure (AR, red label) (grade two): high content of principal components, high purity, interference impurities are very low, suitable for industrial analysis and chemical experiments.
Optical purity is more suitable for drug manufacture, the higher the purity, the less impurities.
The analysis of pure (AR) is the purity specifications of chemical reagents, belong to grade two, analysis of pure tags for Jin Guanghong, for general test (prepared in the quantitative analysis of common solution); for the specific drug purity, different requirements are not the same.
