Trace level signals – Near Detection Limit

To locate and measure trace level signals we must zoom in the Vertical axis much more than the horizontal axis as shown here in this example.  If we do not zoom the Vertical axis we will easily miss trace level signals that might be the answer to a problem or an indicator of unexpected material behavior.
