WebX-axis: m/z (mass-to-charge ratio) The x-axis of 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 IUPAC standard m/z to denote the quantity formed by dividing the mass of an ion by the unified atomic mass unit and by its charge number (positive absolute value). WebThe m refers to the molecular or atomic mass number and z to the charge number of the ion; however, the quantity of m/z is dimensionless by definition. An ion with a mass of 100 u …
WebThis is probably a stupid question but how do you work out the m/z value which is most abundant in the molecular ion peak if there is 75% of 35CL and 25% of 37CL isotopes (75/100 x 35) + (25/100 X35) This gives you 35.5 as the m/z value. 0.
