Abstract
A composition of a focused portion corresponding to a portion of a molecular ion is estimated as a partial composition based on a mass of the focused portion. An initial composition search range is modified based on the partial composition. A composition of the molecular ion is estimated as an overall composition based on a mass of the molecular ion under a modified composition search range. A way of modifying the composition search range may include a method for modifying a lower limit to a range of the number of atoms and a method for adding a new range of the number of atoms associated with a new chemical element.
