Used in discussions, should not be used in publications. Basepeak – this is the most intense ion within the measured (or regarded) mass range. In diagrams it is often set to 100% and the other ions are normalized to this intensity. flindocs

Web13 mrt. 2010 · m/z is the method the instrument uses to sort the ions. A certain mass with a certain charge will give a signal at a certain m/z. If you know the charge (+1, +2, -1, -2, etc) you can determine the mass of the "molecule". You can use Dalton or AMU or grams if you want for your description of the mass. Webmass of the iodine ion in atomic mass units will be 25 27 2.112 10 u 127.19 u. I 1.6605 10 m u u The precisely measured value of the mass of an iodine atom is 126.948 u.

WebMass Resolving Power is defined as m/dm. Where m designates the mass and dm the peak width necessary for separation at mass m. A specific m/z value and also the method like 10% valley or 50% valley or full width at half maximum ( FWHM) must be given.
