Abstract

Disclosed is an apparatus for and a method of mass analysis in which a presence of an accessory substance which is difficult to be analyzed can be recognized visually and clearly. The apparatus for mass analysis analyzes a sample containing a substance to be measured and includes: a display unit; a memory unit storing a theoretical peak obtained by calculation with respect to a region of a mass spectrum of the substance; a matching degree calculation unit calculating a matching degree from multiple peaks that each of the mass spectrum of the sample in the region and the theoretical peak have; a matching degree displaying control unit displaying the matching degree on the display unit; and a superimposition displaying control unit displaying the mass spectrum of the sample and the theoretical peak in a superimposed way in a manner that is consistent with a mass-to-charge ratio.
