Eurospher II: the Logical Choice
After more than 20 years on the market, our Eurospher stationary phase has established a reputation for being a first-class packing material for a wide field of applications.
Eurospher II covers an even wider range of application areas in classical HPLC, fast HPLC Plus and ultra-fast UHPLC. Based on an ultra pure spherical silica gel, Eurospher II is a high performance column material for analytical, semipreparative and process-scale applications. Eurospher II features very narrow particle and pore size distributions, as well as outstanding mechanical stability. Eurospher II silica gel is perfectly suited to take on routine analyses as well as the most ambitious chromatography tasks.
Eurospher II Modifications
With the wide range of different surface modifications available, all application fields in reversed phase and normal phase modes are covered. Every Eurospher II modification offers high chemical stability and loading capacity thanks to mono- and multi-functional silanes. With several different levels of endcapping, Eurospher II offers a wide variety of surface modification types for analytical as well as preparative columns. Our long experience and knowledge in producing HPLC columns ensures the highest reproducibility.

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
Depending on the analytes, three different chiral selectors are available: Amylose-tris-(3,5-dimethylphenylcarbamate), Cellulose-tris-(3,5-dimethylphenylcarbamate) or p-electron donor- and p-electron acceptor groups. Since chiral separations are not always easy to predict, KNAUER offers a chiral screening service for your samples.

Eurokat: Valuable for Food Analysis
Eurokat high performance polymer phases were especially developed for the separation of organic acids, carbohydrates, alcohols and even complex mixtures of these compounds. Eurokat is a sulfonated cross-linked styrenedivinylbenzene copolymer available in several ionic forms (H, Ca, Pb and Ag). This particular cation exchanger is characterized by an outstanding density of functional groups, making it the ideal choice for your ion exclusion, size exclusion and ligand exchange chromatography. Eurokat columns require no organic solvents and thus are environmentally friendly.
Eurokat Application Areas
Four different ionic species are available. Eurokat H is especially designed for the analysis of organic acids and even complex mixtures of acids, sugars and alcohols as well as sugar alcohols. Eurokat Ca and Eurokat Pb are the phases of choice for analysis of smaller carbohydrates (DP < 4), Eurokat Ag is applicable for the separation of sugar oligomers. Eurokat can also be used for the determination of biochemically important molecules such as sugars, artificial sweeteners or acidic metabolic and degradation products.
Choice of Eluents
Outstanding separation results are achieved isocratically with fresh double-distilled water for Pb or Ca, or Ag type Eurokat columns, while Eurokat H columns perform best when using inorganic acids. Such aqueous eluents produce no harmful waste as with organic solvents such as acetonitrile which necessitate expensive disposal.

Eurosil Bioselect: Ideal for the Denaturative Separation of Biomolecules
The Eurosil Bioselect stationary phase was specifically developed for the separation of proteins and peptides. Eurosil Bioselect columns are available in 3 modifications, useful for a wide range of separation tasks involving large molecules up to 50 000 Da.
Strict manufacturing procedures ensure a very narrow pore size distribution. Interfering anions or heavy metal ions on the silica surface are not present in Eurosil Bioselect columns because only ultra pure silica gel and high quality chemical modifications are employed.
Eurosil Bioselect Modifications
Eurosil Bioselect columns for HPLC feature a wide-pore (300 Å) stationary phase and were specifically designed to separate large biomolecules, such as proteins and peptides.

Sepapure® Columns for FPLC
Prepacked FPLC columns for protein purification based on Agarose and Dextran for all common applications: Size Exclusion Chromotography (SEC), Affinity Chromotography (AC) and Ion-Exchange Chromotography (IEX).
The new Sepapure® FPLC column product line offers new high-quality alternatives for Size-Exclusion (SEC), Affinity (AC) and Ion-Exchange chromatography (IEX). The FPLC column line is completing the KNAUER FPLC portfolio and provides the best LC column addition to your FPLC system.
The FPLC columns come as prepacked ready-to-use 1 ml or 5 ml cartridge and can also be purchased as bulk resin. The media for affinity chromatography as well as ion-exchange chromatography is based on agarose, which is well-known in FPLC chromatography. For affinity chromatography the agarose solid phase is functionalized with ligands for purification of recombinantly expressed proteins with His- or GST-tags or antibodies via Protein A or Protein G affinity. The Ion-Exchange columns can be purchased as weak and strong anion or cation exchangers. The basis of our FPLC desalting column is dextran, which reliably separates small molecules and salts from valuable proteins.
With these materials, the FPLC column Sepapure is providing the best columns to use with your precious AZURA FPLC system, giving you a complete and reliable KNAUER FPLC package.
