Supplier: Merck

With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.

Desmosine is prepared according to the method of Starcher et al. from hydrolysed neck ligament by solvent extraction and chromatography on Dowex 50.

Supplier: VARIAN

These hydrophilic polymers are suitable for both aqueous SEC and organic GPC using the majority of polar organic solvents. The two types are chemically similar that can be used together across a wider molecular weight range with aqueous and organic polymers.

Supplier: Resonac

Standard organic solvent SEC (GPC) column.

Supplier: TOSOH Bioscience

These columns are designed for GFC of water soluble organic polymers, polysaccharides, oligosaccharides, DNA and RNA. They are based on a hydrophilic polymethacrylate matrix, which is stable from pH 2 to 12 and in aqueous eluents with up to 50% polar organic solvent.

Supplier: Agilent

These columns are not bonded or cross-linked, and are therefore useful for established methods that do not require the column to have cross-linked or bonded polymer phases. Because SE series columns are not bonded or cross-linked, solvent rinsing is not recommend.

Supplier: Merck

This kit features a convenient selection of pre-qualified standard peptides, proteins, matrices, and solvents for calibrating and testing matrix assisted laser desorption ionisation (MALDI) mass spectrometers.

Supplier: Agilent

Poroshell 120 is made with a superficially porous particle that has a solid silica core and a porous outer layer. This particle provides high efficiency at lower pressures and is ideal for fast or high-resolution separations of many types of analytes.
