VDS

VDS optilab is a German HPLC column manufacturer that is well-known for its VDSpher® phase family. Since 1987 the company has developed various product lines for users who prefer an uncomplicated and rapid HPLC analysis. All VDSpher columns provide a broad selectivity spectrum, superb selectivity, very high purity of the silica gels as well as a narrow pore size distribution and particle size distribution.

All VDSpher phases are based on two different basic silica gels: VDSpher Classic and VDSpher PUR. The main difference is their purity. VDSpher PUR phases are the best choice for analytical HPLC and VDSpher Classic phases are recommended for preparative chromatography. U-VDSpher columns are ideal for UHPLC applications. The VDSpher OptiAqua phases have been specially developed for very hydrophilic applications.

At Analytics-Shop we now offer these and all other phases of the VDSpher product family - HPLC Quality made in Germany!

VDSpher OptiAqua and VDSpher OptiAqua PUR

VDSpher OptiAqua phases are ideally suited for very hydrophilic applications. A special polar endcapping makes it possible to use 100% water as a solvent while still maintaining reversed phase properties.

On the basis of VDSpher Classic & PUR, six VDSpher OptiAqua phases with different modifications as well as pore sizes and particle diameters have been developed. With these phases, numerous applications can be performed in preparative as well as analytical HPLC. Also, analytes of different sizes can be handled optimally. Thus, different molar mass ranges can be covered, depending on the pore size of the modified silica gel.

VDSpher OptiAqua phases can be used e.g. to separate polar substances. Typical analytes are antibiotics, biomolecules, drugs, nucleobases, organic acids, parabens, pesticides, sulfonamides, water-soluble vitamins and xanthines.

All VDSpher OptiAqua phases are pH-stable in a range of 2 to 7.5 and can be used without any problem up to a temperature of 60°C.
