Metrohm has revealed that the Dosino Gradient enables users to achieve good separation of early-eluting anions while maintaining acceptable retention times for late-eluting anions.
The system is said to enable optimum separation in an acceptable time for all anions and all applications.
Using 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.
Therefore, a fully automatic rinsing step can be integrated at the end of a determination series.
