YMC-Pack Chiral NEA (R)

Normal Phase:
YMC Chiral NEA consists of polymeric 1-naphthylethylamine bonded to a wide pore spherical silica. The R and S columns differ in the optical rotation of the CSP; the R column being formed from R-(+)1- naphthylethylamine and the S column from S-(-)1-naphthylethylamine. This results in the two column types having the effect of reversing the elution order of enantiomeric pairs of compounds.

Reversed Phase:
YMC-Chiral NEA columns are as well suitable for reversed phase separation of polar, water soluble compounds particularly pharmaceutical compounds.

Features:

• normal and reversed phase mode
• reversal of elution order
• nonpolar to medium polar compounds
• available in bulk quantities
