Abstract: A laser beam with a wavelength capable of exciting atoms of helium in the metastable state is directed to a generated plasma, and atoms in the metastable state are excited. Absorption amount information representing the amount of laser beam absorbed is acquired, and the density of atoms of helium in the metastable state in the plasma is computed from the absorption amount. The emissions of light from helium gas in the plasma caused by transition from two different excited states to the lower level are measured, and the ratio between the intensities of the emissions is determined. The electron temperature of the produced plasma is computed from the computed density of the atoms of helium gas in the metastable state and the computed emission intensity ratio. With this, the plasma electron temperature can be computed with a relatively high accuracy irrespective of the condition of the plasma atmosphere.

Abstract: An analyzer suitable for performing continuous gas analysis in ultra-high purity applications. The analyser combines a low-level emission source and a gaseous emission spectrometer (10) having a charge coupled device (CCD) diode array as a detector. The CCD detector replaces one or more photomultipliers and narrow bandpass filters typically used in spectrometers. The analyser performs various processing operations to evaluate and eliminate the effect of background light level, or dark spectrum.

Abstract: An ionization chamber of an analytical apparatus (10) in which high concentration test sample ions are evaporated is provided with an ion introduction control means (8) to control the quantity of the test sample ions introduced to an ion attracting electrode (9). Therefore, an analytical apparatus can be provided that is capable of substantially simultaneous mass spectrometry and absorption, emission, and scattering spectroscopy. The apparatus also includes: a low temperature bath (106) which cools the test sample solution before it is introduced to the sprayer (104); and a cooling gas introduction tube (108), constructed separately from the sprayer, which cools the sprayer and the test sample solution introduced to the sprayer (104). The inclusion enables effective restriction of test sample heating upon high voltage application. Mass spectrometry and absorption, emission, and scattering spectroscopy can be substantially simultaneously carried out even when the test sample used is stable only at extremely low temperatures.
