Purification by HPLC in preparative scale because of its
numerous benefits is increasing in importance and becoming a
routine procedure. Based on the fact that the amount of applicable
sample is proportional to the column size, the COSMOSIL series is
available in 10mm I.D. and 20mm I.D. for semi-preparative
applications and 28mm I.D. and 50mm I.D. for preparative scales.
For column sizes and packing materials not listed below, contact
either your local distributor or the manufacturer directly.
