KNAUER Eurospher II Chiral OM Prep Columns for NP & RP (USP L40, USP L93)

Eurospher II Chiral OM uses the chiral selector Cellulose-tris-(3,5-dimethylphenylcarbamate) and is equivalent to Chiralcel OD. KNAUER offers 2 different CPS versions: Eurospher II Chiral OM is designed for separations in normal phase (NP) mode and Eurospher II Chiral OM-R for separations in reversed phase (RP) mode.

Properties

• Silica gel: ultra pure, > 99.99 %
• Metal content: < 10 ppm
• Particle size: 3 μm, 5 μm, 10 μm
• Particle form: spherical
• Pore size of base material: 1000 Å
• Chiral selector: Cellulose-tris-(3,5-dimethyl- phenylcarbamate) for Chiral OM

Key features

• KNAUER offers these chiral stationary phases for two different separation modes: Eurospher II Chiral OM is designed for separations in normal phase (NP) mode, Eurospher II Chiral OM-R for separations in reversed phase mode.

Recommended application areas

• Eurospher II Chiral OM columns are able to separate neutral, acidic and basic racemates.

Eurospher II Chiral

Based on ultra-high purity silica, the Eurospher II chiral column materials are characterized by high enantioselectivity and loadability. 

Available in a wide range of dimensions for analytical, preparative and SMB (simulated moving bed) applications, Eurospher II Chiral columns are the perfect choice for even the most challenging enantioseparation tasks 

Since chiral separations are not very well predictable, KNAUER offers a chiral screening service for your samples (Article number: AL0220).

Tip: Some of the most popular eluents for HPLC (such as acetone, chloroform, DMF, DMSO, MEK, toluene, dioxane, ethyl acetate, methylene chloride, pyridine and THF) which may be remaining in your HPLC system, can destroy Eurospher II Chiral AM and OM phases even in small concentrations! It is highly recommended that the HPLC system is flushed with appropriate eluents before the installation of the chiral column.
