Crownpak ® the CR-the I (+) / the CR-the I (-)
Solvent-borne crown ether chiral column
Crownpak ® the CR-the I (+) / the CR-the I (-) bonded to the surface of silica gel chiral crown ethers, chemically bonded manner, chiral filler immobilized on silica gel.
Professional separation of amino acids, amino alcohols, amines and other chiral centers next to a class of amine compounds.
All HPLC solvents are available!
Typically, an acidic mobile phase, such as a perchloric acid aqueous solution having a pH of 1.0 to 2.0, is used.
However, it is also possible to use a solvent with a stronger elution force as the mobile phase, greatly reducing the analysis time.
Crownpak ® the CR-the I (+) and Crownpak ® the CR-the I (-) two chiral column can be referred to each other, opposite elution order samples.
