VDSpher PUR phases
The VDSpher phases we offer here are based on the basic VDSpher PUR silica gel. The VDSpher PUR silica gels are suitable for analytical, semi-preparative and preparative scale. However, to achieve the best possible column packing, VDSpher PUR phases are a good choice for analytical HPLC. VDSpher PUR phases are characterized by a lower metal content, which causes less retardation compared to phases with a higher metal content.
Normally, the standard phase VDSpher PUR 100 C18-E is a good starting point for many separations, e.g. for the isolation of natural products, for the determination of caffeine in coffee or tea and even for the determination of amino acids. VDSpher PUR 100 C18-E is of medium hydrophobicity and shows low silanol activity.
We offer more than 350 VDSpher columns for various needs in our Analytics Shop. Feel free to contact our experts if you need help choosing the right column.
