Even though the Cogent NP Amino™ HPLC column is an excellent choice for non-hexane, normal phase chromatography, it is also very useful for highly acidic compounds using methanol or acetonitrile in reversed phase.

IMPORTANT NOTE:
When the Cogent Amino™ column is labeled for normal phase, (denoted as Cogent Amino NP column) it is shipped in 90/10 heptane/ethyl acetate.
When the Cogent Amino™ column is labeled for reversed phase, (denoted as Cogent Amino RP column) it is shipped in methanol so one can easily go into reversed phase solvents.
