Threshold
.
In
Threshold
mode, the 2D-LC Valve is triggered on the threshold of the
detector signal. The threshold value is given as mAU value. When the UV
signal rises above this value, with a certain delay the 2D-LC Valve is
triggered and switches to cut the fraction. The 2D-LC Valve will switch to the
next position when the UV signal falls below this value or the cut size elapse.
[OPTIONAL]
b
Or set the
Slope
.
In
Slope
mode, the 2D-LC Valve is triggered on the slope of the detector
signal. Adequate values for Up Slope and Down Slope can be specified in
the corresponding fields. This value is given as mAU/second. The 2D-LC
Valve switches when the up slope exceeds the given value. Cutting ends
when the slope passes a minimum and then rises above the down slope
value or the cut size is elapsed.
