Supplier: Avantor

Avantor® Alltima HP columns features for general purpose normal-phase applications.

Supplier: Avantor

Ultra-clean, PP columns with BAKERBOND® HPLC media are engineered to save time, minimise work and final solvent volumes and improve performance. Run times are up to nine times faster than conventional columns. The built-in column guard filter and higher analyte concentration may reduce or eliminate pre-filtration and concentration steps.

Supplier: Retsch GmbH

The Retsch analytical air jet sieve shaker is particularly suitable for dispersion and deagglomeration of fine powders. Typical applications include construction materials, flour, spices, plastics and pharmaceuticals. The evaluation software EasySieve® can be used for automated evaluation and documentation.

Column type: HPLC column, Silica, Silica analytical guard column starter kit (1 holder, 2 cartridges) for steel columns with 2,1×20 mm guard column, Ø int.: 2,10 mm, Length: 20 mm

Supplier: Merck

Selection of Merck's standardised and modified silica gels that are available in many granulations and supplied from one single source, dedicated to chromatography. Standardised silica gels are widely used in separation processes to purify valuable compounds in ton quantities. Modified silica on the other hand is used in separation problems, which cannot be adequately solved using unmodified silica.

Hypersil™ Silica columns are suitable for normal phase chromatography of non-polar and moderately polar organic compounds.

Supplier: Agilent

Packed GC columns are designed and manufactured to offer excellent and reproducible performance for all sample types associated with packed column separations, most important in the hydrocarbon processing industry.

Supplier: Merck

HPTLC plates, unmodified silica gel 60
This range of plates uses an optimised Merck silica gel 60 with a particle size of only 5 to 6 µm, which results in higher packing density and a smoother surface, therefore, reducing band diffusion. Less sample is required, 0,1 to 0,5 µl than for classic TLC.

Supplier: VWR Chemicals

VWR® powder pack reagents are designed to be used on laboratory and portable photometers with 16 mm cell capability. No calibration data is necessary. The pillows, individually sealed in aluminium foil packs, are unaffected by ambient conditions and contain pre-measured powder reagents for accuracy, convenience and great solubility.

Supplier: MICROSOLV

Cogent TYPE-C Silica™ is HPLC grade silica with a silica hydride surface. Their unique stationary phase will adsorb and desorb solvents commonly used in mobile phases very differently from ordinary silica resulting in excellent benefits to the chromatographer. Excellent for normal phase chromatography and solvent drying is not needed.

Supplier: Agilent

Pre-aligned fused-silica capillaries from Agilent Technologies are designed and optimised for ease of use and reliability. All capillary ends are cut to a smooth, mirror-like finish. In addition, the polyimide outer coating is removed from the ends. These processes ensure minimal sample adsorption and help maintain sharp peak shapes. All capillaries have a pre-made detection 'window' and a built-in alignment stopper that allows rapid and precise insertion in the alignment interface.

Supplier: Thermo Fisher Scientific

This TLC high purity grade silica gel without binder is used for thin layer chromatography plate preparation.

Supplier: Thermo Fisher Scientific
