You do this with a Restek column! You cannot get a better resolution by changing just parameters with this cphase. You need a different selectivity to have a chance, maybe use a DB-WAX UltraInert.
For glucose a 87H type is ok as it uses Ion Exclusion Chromatography for the separation, the phases contain benzenesulfonic acid group (and will interact with anions in ion exchange mode). Phosphoric acid does not interact with sulfonic acid groups as…
thanks for sharing the information. It saved my day. But to delete the mentioned file I had to call helpdesk to grant me permission. No way to delete with my regular credentials.
