- Use when samples need to be pre-absorbed onto loose sorbent material
- Suitable for dry loading and packing home-built columns
The TELOS bulk sorbents for flash chromatography dry loading are available in silica, NH2 (bonded aminopropyl), C18 (octadecyl), and NM (diatomaceous earth). Silica, NH2, and C18 have 40 to 60 µm particle size and pore size of 60 Å. These sorbent materials allow samples to be pre-absorbed before loading onto the top of a flash column.
