WebThe x-axisof a mass spectrum represents a relationship between the mass of a given ion and the number of elementary charges that it carries. This is written as the IUPACstandard m/zto denote the quantity formed by dividing the mass of an ion by the unified atomic mass unitand by its charge number (positive absolute value). WebA spectrogram is like a photograph or image of a signal. A spectrogram plots time in Y-axis and frequencies in X-axis. A spectrogram also conveys the signal strength using the colors – brighter the color the higher the energy of the signal. A spectrogram explains how the signal strength is distributed in every frequency found in the signal. honda of north richland hills inventory
