Computer controled, programmable splitter. Choose the ratio between 2 detectors
Typically the split between 2 detectors is controlled by the length and diameter of the capillary lines leading to the detectors. To get a different split, the instrument must be shut down to modify the hardware.
With the VarioSplit, the ratio is now programmable and can be change by a click of the mouse.
Enlarge Image- Variosplit Dome
Enlarge ImageThe VarioSplit is based on a dome splitter. One input (from the column), two control lines and two outputs (to the detectors) are enclosed in a dome. By modulating the flow of the control lines the eluent is diverted more toward a detector than the other. The overall flow to the detector remains constant.

Enlarge ImageTypical ratios (det1:Det2) are programmed such as 100.0%-0% (everything to detector 1), 0-100 (everything to detector 2), 80%-20%, 50%-50% and so on...
The varioSplit is software controlled
Two modes are available:
- Manual: the user set the ratio by clicking on user set buttons.
- Automatic:
You program the changes of ratios during the run
You program the ratio set for a sequence of runs
For best performances, the remote start option is higly recommended ( It is required to set the ratios for a sequence of runs)
For complex GC systems several variosplit can be installed on hte same GC.
