Dosino Gradient – Upgrade your Ion Chromatograph to a Powerful Gradient IC System

How to achieve the best possible separation of early-eluting anions while maintaining acceptable retention times for late-eluting anions? The Dosino Gradient is the answer to this notorious challenge. Metrohm’s Dosino Gradient enables optimum separation in an acceptable time for all anions and all applications.

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 NetTM 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 a the end of a determination series.
