Avantor® ACE® Silica columns provide great reproducibility and column lifetime. These stainless steel columns are available in a wide range of particle sizes and dimensions from capillary to preparative.

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: ISERA

HPLC column of the ISAspher line guarantee the highest possible reliability in a wide range of applications.

Supplier: TCI

Palladium 0.1 mmol/g on SH silica gel

Supplier: Thermo Fisher Scientific

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

Supplier: VARIAN

The fused silica retention gaps has three different polarities, uncoated for universal applicability. Dimensions equal to 0,53 mm int. Ø fused silica provide easy installation.

Supplier: Merck

Highly robust plates with gypsum as binder, fully compliant with international pharmacopoeia (Ph. Eur. and USP).

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: Thermo Fisher Scientific

Silicon(IV) oxide is used in the manufacture of glass for windows, drinking glasses, beverage bottles and many other materials. Optical fibers for telecommunication are made from silica. It is also used as a raw material for many ceramics such as earthenware, stoneware and porcelain. In addition, silica is a common additive in the production of foods and pharmaceutical products.

Supplier: Thermo Fisher Scientific

Supplier: MACHEREY-NAGEL

Reagents for the determination of silica in water samples.

Supplier: MACHEREY-NAGEL

The retention gap technique in combination with on-column injection allows concentration of a large sample volume in the capillary column. The retention gap depends on the solvent used:

Supplier: Thermo Fisher Scientific

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

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.
