Achieve optimum separation with gradient How to achieve the best possible separation of early-profiles. A step gradient, where a change from a weak eluting anions while maintaining acceptable retention eluent to a stronger eluent takes place after a defined times for late-eluting anions? The solution to this prob-time, is the basic profile.

lem is the Dosino Gradient. The Dosino Gradient enables you to achieve optimum separation in an acceptable More complex profiles can also be programmed easily analysis time for all anions and for all applications.

with MagIC NetTM ion chromatography software. Linear changes in eluent composition can be made. One of the Even quinary gradients are not a problem five eluent connections can, alternatively, also be con-With the Dosino Gradient, up to five eluents can be nected to a rinsing solution. Thus, a fully automatic rins-combined and moved with a single double-piston high-ing step can be integrated at the end of a determination pressure pump. The system enables different gradient series.
