Tandem Operation of gradient methods for water soluble vitamins

Instrument Type: HPLC

Many fast UHPLC and traditional HPLC methods suffer under delays caused by the need to wash and equilibrate the column after the separation. Typically we see 20%–40% of the runtime used up by these essential steps within a gradient method. Here a solution utilizing a dual-gradient pump setup with column switching capabilities to overcome these delays without the need of redeveloping existing methods is offered. The Thermo Scientific™ Dionex™ UltiMate™ 3000 LC Dual System with the Viper Tandem Operation kit allows to sppeding up gradients in LC and UHPLC assays.
