VDS HPLC Column VDSpher PUR 100 NH2. 5 μm, 4 x 250 mm

Name: VDS HPLC Column VDSpher PUR 100 NH2. 5 μm, 4 x 250 mm
Brand: VDS

VDSpher PUR 100 NH2 is an alternative HPLC Column to Purospher STAR NH2 Both unmodified and several modified silica gels are available for normal phase (NP) chromatography. This enables a large number of normal phase separations. The advantages of chemically modified silica gels, which allow rapid equilibration, reproducible, are particularly noteworthy Analyzes despite fluctuating water content in the mobile phase and a problem-free application of gradient methods. Depending on the type of modification, various mechanisms can be used for the separation: SIL: polar interactions, high silanophilic activity Diol: polar interactions, hydrogen bonds, silanophilic activity CN: polar interactions, π-π interactions, hydrophobic interactions, very low silanophilic activity CN-SE: polar interactions, π-π interactions, hydrophobic interactions, no silanophilic activity NH2: polar interactions, hydrophobic interactions, ion excMostra di più
