WebYou'll see this written as m over z in a lot of mass spectrometry examples. m over z is the mass-to-charge ratio. For our purposes, we're just trying to think about how the mass affects the radius of the circle that the ion will move in. So, we've seen, if you increase the mass, you increase the radius. WebThe application of superimposed radio frequency and constant potentials between four parallel rods can be shown to act as a mass separator in which only ions within a particular mass range will perform oscillations of constant amplitude and be collected at the far end of the analyzer. This device has the advantage of high transmission.

WebTypically mass spectrometry alone is unable to meet this need as it can only differentiate compounds by their mass-to-charge ratio (m/z) which is insufficient in most practical applications of the technique. For example, more than 1,500 compounds may have the same molecular mass at around 250 Da. WebThe x axis is the mass to charge ratio (m / z), where z is usually 1. The y axis is the relative intensity (how often is the ion observed compared to the most common ion (the base peak)). The MS of a typical hydrocarbon, n-decane is shown below. The molecular ion is seen as a small peak at m/z = 142. C10H22 = (10 x 12) + (22 x 1) = 142 g/mol.
