An elemental imaging method using a laser ionization orthogonal time-of-flight mass spectrometer system was developed for the simultaneous detection of all metal and nonmetal elements. The instrument control and data processing were realized by self-developed programs. This system is capable of simultaneous detection of metal and nonmetal elements, with a spatial resolution of 50 μm, the lowest detection limits of 3 × 10(-7) g/g (Li), and a dynamic range of 7 orders of magnitude. Moreover, this technique does not require standards for quantitative analysis and can be a powerful and versatile tool for elemental imaging.
