InfinityLab Quick Change Valves for column switching are an orderable add-on
option for the InfinityLab Multicolumn Thermostat.
Multicolumn Selection (G7116B with G4239C)
Advantages
• Increase productivity
• Higher instrument up-time
The valve facilitating quick changes allows the selection between up to eight
different stationary phases for a variety of applications, or the usage of identical
stationary phases in columns with different dimensions for either faster
run-times (short columns) or higher resolution (long columns) or for loading
studies with different internal diameters.
