Chiral Polymer-bonded Silica Gel for Optical Isomer Separations YMC Chiral NEA (R) and (S) are chiral polymer-bonded silica gel for optical isomer separation. Chiral discrimination is based on the higher-order structure of chiral macromolecules, which includes hydrogen bonding, π−π interaction, hydrophobic interaction, etc. YMC Chiral NEA stationary phases exhibit excellent durability and are cost effective chiral solutions.
YMC’s Guard Column Cartridge Systems for HPLC accept cartridges of 1.0, 2.1, 3.0, or 4.0mm inner diameters – in either 10mm or 20mm lengths. Cartridges are available with a comprehensive selection including all stationary phase chemistries offered by YMC, ensuring compatibility between the guard column and the analytical column. Assembly is tool-free, simplifying cartridge replacement.
YMC Guard Column Cartridges require the use of a holder, P/N: XPGCHP1 for 10mm length and P/N: XPGCHP2 for 20mm length.
