Marking of Detected Peak
 When an independent peak is detected, a short green line would be marked to indicate the Start Point and a short red line would be marked to indicate the End Point of the peak together with its Retention time. If a few connecting peaks are treated as split, (refer to the diagram below) each of the peak would have its own Start Point and End Point as shown below. Should the End Point of one peak coincides with the Start Point of the next peak, a short green line would be displayed instead. The Baseline that we use to integrate the area of each peak is the line that connects the Start Point of a peak to its respective End Point.

If two connecting peaks are treated as overlap, (refer to the diagram below), a short green line would be marked to indicate the Start Point of the group of peaks, another short green line would be marked to indicate the Valley Point. A short red line would be marked to indicate the End Point of the group of peaks. When integrating the area of each peak, a vertical line is dropped from the Valley Point to the Baseline, which is the line that connects the Start point of the group of connecting peaks to the End Point of the group of connecting peaks.
