    摘要： Irregular mechanical imperfections caused by constituent parts of a monochromator in connection with wavelength setting are compensated by calibrating the monochromator according to the present invention. A whole measurable spectral range in the monochromator is divided into a plurality of spectral regions by a plurality of calibration wavelengths. Errors between apparent wavelengths set theoretically and their true wavelengths are obtained with respect to the respective calibration wavelengths. Error functions in connection with the respective spectral regions are calculated on the basis of the array of the obtained errors. An element to be detected in a sample is measured under a wavelength the error of which has been compensated for by use of an error function in a spectral region associated with a wavelength to be detected.

    摘要： In order to provide an equipment that permits easy elimination of interference ions even in a low resolution mass spectrometer, the isotope mass number information and the isotope presence ratio information for each element are stored, and processing is done as is shown in FIG. 1 using such information and the measurement results, and the amount of target elemental ions is calculated by calculating and eliminating the amount of interference caused by other elemental isotopes to the target element. Because of this, when carrying out element analysis using a mass spectrometer with a relatively low resolution, the user can easily obtain the measurement result of the amount of any target elemental ions.

    摘要： A plasma ion source mass spectrometer comprising a plasma ion source 40 for ionizing a sample with a plasma; a mass filter 60 for subjecting the sample ionized by the plasma ion source 40 to mass spectrometry; and an interface unit 50 having an orifice formed in a cone 52, 54 for introducing the sample ionized by the plasma ion source 40 into the mass filter 60. Further the plasma ion source mass spectrometer comprises a first cooler 49 for cooling a plasma generator 41 of the plasma ion source 40 and a plasma generating power source 44; and a second cooler 56 independent of the first cooler 49, for cooling the interface unit 50 and for raising the temperature by changing the cooling efficiency so as to reduce the influence of deposition on the interface unit 50. With this construction, the temperature of the interface unit can be controlled without changing the analysis sensitivity of the plasma ion source mass spectrometer.
