KNAUER offers an extensive range of columns and phases for HPLC. Our 35 years of experience in the field of liquid chromatographic separation techniques is evidenced by each and every column we deliver. High performance quality sorbents such as our very own Eurospher provide for excellent results. The process of manufacturing our HPLC separation columns has been thoroughly optimized. Strict criteria guarantee outstanding quality in batch-to-batch reproduction.

We design and manufacture HPLC column hardware ranging from 2 mm ID to 62 mm ID. Column lengths range from 5 mm up to 300 mm. The standard column hardware is made of high quality stainless steel with a specially treated inner surface. PEEK columns for biocompatible applications are also available. Many models can be equipped with an integrated precolumn.

Some of the packing materials which KNAUER has to offer include: ( = PDF datasheet for download )

•	Eurocel - high performance chiral materials for many chiral HPLC separation tasks. This range of polysaccharide-based chiral HPLC columns features high loadability and remarkable eluent flexibility. A set of derivatizations (-3,5-dimethylphenylcarbamate, -benzoate, -4-methylbenzoate, -phenylcarbamate) with graded selectivity is available with particle size from 3 µm up to 20 µm
•	Eurokat - crosslinked styrene-divinylbenzene copolymer for the analysis of carbohydrates and organic acids
•	Eurosil Bioselect 300 - C4 or C18 material with a large pore size specially for the purification of peptides and proteins
•	Eurospher 100 - premium, silica-based, spherical packing material with a narrow pore size distribution for a wide range of analytical and preparative HPLC applications NEW: C18 phase now also available with 3 µm particle size
•	Kromasil 100 - high efficiency silica gel for analytical to process-scale separations
•	LiChrosorb 60, 100 - rugged, well-established, irregular silica material
•	LiChrospher 60, 100 - established, spherical alternative to LiChrosorb
•	Nucleosil 100, 120, 300 - spherical, silica-based for a wide range of applications
•	ProntoSIL 60, 120, 200, 300 - ultra-pure silica-based material with a wide pH range
•	ProntoSIL Hypersorb ODS - spherical type A silica, alternative to Hypersil ODS material
•	Sphere-Image 80 - alternative to Spherisorb material, available in all typical modifications
•	Superspher 60, 100 - high performance silica gel with a average particle size of 4 µm for analysis of complex mixtures

Some of the available surface modifications are:
Si, Diol, NH2, C1, C4, C6H5, C8, C8 SH, C18, CN, RP8, RP18, RP18 endcapped, RP select B.

Every column manufactured by KNAUER is individually tested and is delivered with a quality certificate and test report.
