Hello,

I have a question about the column CHO-99-9864 (CARBO SEP COREGEL-87P)
The column Carbo Sep Coregel 87P will be a column appropriated in order to analyse the molecule of arabinose and mannose ?

Many thanks in advance

HI!!

The 87P would only provide ~30 seconds between peaks of Mannose and Arabinose. The CHO 682 column (PN: CHO-99-9854) would give 1.5min separation between peaks.
The issue with the CHO 682 is that it holds onto carbohydrates longer...thus gives better separation. So, arabinose would elute ~16 min from the 87P column, but 24min on the CHO 682 column.

Have a good day
