All quantities are in Gaussian (cgs) units except energy and temperature which are in electronvolts. The ion mass is expressed in units of the proton mass and the ion charge in units of the elementary charge (in the case of a fully ionized atom, equals to the respective atomic number). The other physical quantities used are the Boltzmann constant (), speed of light (), and the Coulomb logarithm (). ready made brick mortar

Web2 dagen geleden · amu - atomic mass unit, a historic unit for atomic weight - it is based on the 1/16th part of the 16 O mass. 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. 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. http://www.lc-ms.nl/repeating_units.htm ready made buildings
