INSTRUCTION MANUAL FOR CROWNPAK® CR(-) CHIRALPAK® MA(+) 3 µm Ligand Exchange CHIRALPAK® WH CHIRALPAK® OP(+) Polymethacrylate . INSTRUCTION MANUAL FOR CROWNPAK® CR-I(+) Shipping solvent of CROWNPAK CR-I(+)/CR-I(-) columns are H 2 O/MeOH=95/5. To switch from reversed phase mode to normal phase mode, and vice versa, column should be carefully flushed with miscible solvent (ethanol and 2-propanol).

With CROWNPAK® CR(+), the D-form of amino acids always elutes in first position. Using CROWNPAK® CR(-) will result in an inversion of the elution order. ® CR(+) / CR(-) COLUMNS ® CR(+) / CR(-) eet completely before using these columns North Five Points Road West Chester, PA Tel: Fax: INSTRUCTION MANUAL FOR CROWNPAK® CR-I(+) and CROWNPAK® CR-I(-) Please read this instruction sheet completely before using these columns These columns can also be used in reversed phase mode.
