Comparison between NH2P-40 3E and its Conventional Type (NH2P-50 4E)
Asahipak
NH2P-40 3E is filled with smaller-sized gel, 4 micro-m, and packed in a 3.0 mm internal diameter (I.D.) column housing. The selected ID size allows the column to be used with a conventional LC system, i.e., without a need of semi-micro or any other special LC system. NH2P-40 3E provides higher resolution compared to Asahipak
NH2P-50 4E. NH2P series is one of the best fits for the saccharides analysis using HILIC mode. The solvent required for NH2P-40 3E column is approximately 1/3 of the NH2P-50 4E column.
