WebFluorescence Detector. 8. Chemiluminescence Detector. 9. Optical Rotation Detector. 10. Electro Chemical Detector. The actual separation of each component in the sample is carried inside a column; however this separation needs to be "collected" for us to be able to see it. The detectors are used for this purpose. WebFind peaks inside a signal based on peak properties. This function takes a 1-D array and finds all local maxima by simple comparison of neighboring values. Optionally, a subset of these peaks can be selected by specifying conditions for a peak’s properties. A signal with peaks. Required height of peaks.
