An increasing number of flash chromatography methods require samples to be pre-adsorbed onto loose or bulk sorbents. The sorbents used to manufacture TELOS Flash Chromatography Columns are available as loose material. The materials allow samples to be pre-adsorbed, the solvent removed and the resulting sample-sorbent blend to be applied to the sample loading device or directly onto the top frit of the flash column.
TELOS Bulk Sorbents are available in silica, NH2 (bonded aminopropyl), C18 and the diatomaceous earth, TELOS NM.
The availability of the same sorbents used to manufacture TELOS Flash Chromatography Columns ensures consistency and identical selectivity for all separations.
