WebJun 9, 2024 · peaks (sequence): Peak indices in x. rel_height (float): Selects the relative height at which the peak breadth is expressed as a percentage of its prominence. The breadth of the peak is calculated at its lowest contour line at 1.0, and half the prominence height is calculated at 0.5. WebThus, slower migrating compounds will have the same peak height but a larger peak area than faster migrating compounds. Therefore, it is common to work with corrected peak areas, i.e., peak area divided by migration time. The work on a racemic mixture of enantiomers demonstrates the importance of this correction.
