"I use Merck Purospher C-18 columns for regular testing of herbal products. I find this column good and long lasting."
The base silica of Purospher® STAR columns is 99.999 % pure.
Furthermore, meticulous care is given to quality control over all aspects of silica structure and chemistry. The excellent converge of the surface and the purity of the material ensures excellent peak symmetry for acidic, basic and even for chelating compounds.
