Use the sliders to tune the three basic integration parameters, plus options for the peak separation mode.
Depending on the selected integrator, the following integration parameters are available as sliders:
ChemStation integrator
Peak width: Step slider. The steps are chosen by the application in a size that has an actual effect on the integration.
Slope sensitivity: Use this continuous slider to define a threshold for the signal slope.
Higher values mean that a greater signal slope is required to define a peak, which means that there will be fewer peaks.
Peak reject by: You can reject peaks by area (default) or by height. The initial value is 80% of the smallest peak that you have specified in the first step. No matter which of the two values you adjust with the slider, Area reject or Height reject, the respective other integration parameter is automatically adjusted as well and can be edited in the integration events table.
Peak separation mode: Choose how you want to integrate peaks that do not show baseline separation. For Gaussian skim, Exponential skim and Straight skim, you can additionally tune the skim ratio. For ChemStation integrator, the peak separation mode will apply to all signals in the method.
EZChrom integrator
Width: Step slider. The steps are chosen by the application in a size that has an actual effect on the integration.
Threshold: Use this value to distinguish the start and stop of peaks from baseline noise and drift.
Minimum area: The initial value is 80% of the area of the smallest peak that you have specified in the first step.
Peak separation mode: Choose how you want to integrate peaks that do not show baseline separation.
The value ranges of the sliders are set automatically based on the selected injection, or based on an existing processing method.
