Industrial Grade Column Chromatography Silica Gel(ZCX-Ⅲ-GY)
1. Performance: The product is white powder-like particle, which is get through air smashing, extension, filtering and other processing. We add air mixing process into production, which significantly change the shape of particles, the particles are almost circular or elliptical, increase the specific surface area, and improve the separating effect.
2. Application: Analysis and purification of pharmaceutical, chemical intermediates
Processing of the spring crude special intermediate
