2 columns With the OPTIC-4 control software (Evolution Workstation 4.5 and newer) it is now possible to configure two columns in series. Evolution Workstation calculates the effective column length and diameter in order to ensure constant flow programming.

Deans’ Switch

A full control of a Deans’ Switch is now also possible with the OPTIC-4. An OPTIC-4 auxiliary flow module, 3/2 way valve and a SGE SilFlow™ Deans Switch Kit is all what is needed. The OPTIC-4 takes care about correct flow programming and the 3/2 way valve actuation. One of the possible hardware configurations is shown in the picture below.

Deans’ Switch technology is used for heart cutting, inlet switching, column switching, detector switching, etc.

Next to the Deans’ Switch we are working on GC Flow Modulation controlled by the OPTIC-4. Send us an e-mail if you like to get more information about the Flow Modulation solution.
