With the Dosino Gradient as many as five eluents can be combined and moved with a single double-piston high-pressure pump. The system enables different gradient profiles. A step gradient, where a change from a weak eluent to a stronger eluent takes place after a defined time, is the basic profile.

More complex profiles can also be easily programmed using the MagIC Net ion chromatography software. Linear changes in eluent composition can be made. One of the five eluent connections can, alternatively, also be connected to a rinsing solution. Thus a fully automatic rinsing step can be integrated at the end of a determination series.
