Polymer-based Asahipak NH2P-50 4E column has resolved the problem occurring with silica-based amino columns, whose performance falls with the time.
1) Conventional analytical methods used for silica-based amino columns can be applied to the NH2P column.
Eluent ---- Mixture of water and acetonitrile which is commonly used for silica-based amino columns can be also used.
Column temperature ---- Can be analyzed at room temperature
2) Excellent quantitative analysis can be performed using NH2P column.
3) Further more, the NH2P column can be washed with alkaline solvent.
Sample :
1. Fructose
2. Glucose
3. Sucrose
4. Maltose
