I have five different columns from Dr.Maish:
1) ReproSil - XR 120 NH2
2) Reprosil 80 NH2
3) Reprospher 100 CN
4) Reprosil - Pur 120 NH2
5) Reprosil Saphir 100 NH2
4) Reprosil - Pur 120 NH2
Can I analyse the sugars on them?
I've tried ReproSil 80 NH2 with ACN:water (80:20) as a mobile phease and RI detector, hovewer lactose, glucose and galactose outcome as a one peak.
Have someone used some from mentioned columns for this purpose? Can someone recomend some mobile phase?
