by BISCHOFF
ProntoSIL Si is the type B silica support of BISCHOFF Chromatography used by B & W Separation Technology. Type B silica supports are ultra pure silicas based on Tetraethoxysilane (TES). ProntoSIL SI can be used in normal phase chromatography and is the support for most ProntoSIL bonded phases. Due to the fact that it is manufactured under very stringent conditions ProntoSIL SI has a purity of 99,999%. It is available in several particle and pore sizes. Therefore a wide range of application are given, i.e. SEC, NP-HPLC and NP-HPLC of large molecules.
