Comparison of NH2P with Silica-based Amino Column (1)
Polymer-based Asahipak NH2P-50 4E
column has resolved the
problem occurring with silica-based amino columns, whose performance falls with
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.
