- X-ray analyzers
X-ray analyzers are used in combination with electron microscopes, to analyze elements in micro-area with a sample surface at the micrometer level. Samples irradiated with an electron beam produce a specific X-rays with a particular type of element, and the intensity of the X-rays is measured to analyze the element. This technology can be used effectively in a broad range of micro-field analysis applications, including scientific and chemical applications, as well as semiconductors.

- X-ray fluorescence analyzers
With these devices, fluorescent X-rays produced by irradiating a sample with X-rays are used to analyze the elements of the sample. These analyzers include wavelength dispersion models, which analyze the fluorescent X-rays based on the wavelength, along with non-dispersion models used when the light does not form a spectrum. Non-dispersion models include energy dispersion models that use a detector with a discriminating function based on energy. All of Horiba's instruments are energy dispersion types, whereas OI's instruments include both energy dispersion types and energy dispersion and wavelength dispersion instruments in combination.
