Description:

The parameter indicates whether the spectra search compares the number of extrema in the reference spectra with the ones in the peak spectrum.

 Note:

If there is a high noise level (see Signal-to-Noise Ratio), it is possible that noise peaks are considered extrema. In this case, Dionex recommends disabling the Check Extrema option.
