摘要： The present invention is applied to an analyzer according to which a sample to be analyzed is moved through a capillary tube in liquid chromatography or capillary-zone electrophoretic method. The capillary tube has a separation zone and a detection zone. The capillary tube in the detection zone has a section in which it can vibrate and both ends of this section are fixed.Analytes of the sample introduced into the analyzer are separated from each other in the separation zone. When each of the separated analytes is led to the area irradiated with beam in the detection zone, the capillary tube in the detection zone vibrates. This vibration phenomenon is brought about by tension fluctuation of the capillary tube caused by intermittent irradiation of the detection zone with an excitation beam and absorption of the excitation beam by the analyte. Concentration of analytes in the sample can be measured by detecting amplitude of the vibration.

摘要： The power density of a pulsed laser beam for irradiating a sample is adjusted to break down the sample into the form of a plasma. After the momentary breakdown of the sample into the form of a plasma, ions are generated having a high charge. Then, after a certain time elapses, the ions having a high charge recombine with the electrons in the plasma to provide monovalent or low valent ions. These low valent ions are taken out of the plasma and introduced to a mass spectrometric apparatus.

摘要： A standard containing the same elements as a sample is prepared. Concentrations of the elements of the standard are known previously. When signal intensities of an element of the standard solution and the sample exceed an upper limit of a pulse counter of an element analyzing apparatus, a transmitting rate of a passage, through which ionized elements of the standard and the sample pass, is controlled to be less than the ordinal transmitting rate of the passage in synchronism to the passing time of the elements. The concentrations of the elements of the sample is calculated based on output signals of the pulse counter concerning the elements of the standard and the sample and known concentration of the standard.

摘要： A plasma mass spectrometer generates an aerosol of a sample, by dissolving the sample in a liquid solvent, and spraying the liquid into a spray chamber via a nebulizer. The solvent condenses in the spray chamber and an aerosol of the sample then passes through a supply tube to a plasma torch. Microwave power from an output on the plasma torch converts the aerosol to a plasma, and the plasma passes to an analyzer. If microwave radiation reached the spray chamber, it would cause heating of the solvent which may evaporate it so that the solvent would be present in the plasma. Therefore, there is a wall between the spray chamber and the plasma torch and microwave output which blocks such microwave radiation.

摘要： A spectral source comprises a lamp containing an anode and a cathode in an inert gas. The anode and cathode are different in shape and connected to a high-frequency power source to produce a high-frequency discharge between the anode and cathode to cause both sputtering of the cathode and excitation of a radiation having the spectrum according to the material sputtered from the cathode. The application of solely high-frequency power prevents adherence of the sputtered material to the interior walls of the lamp bulb thereby allowing a reduction of the dimensions of the lamp bulb, prolongating the life time of the lamp and increasing the stability and intensity of the radiation. A magnetic field may be applied to the radiation for Zeeman modulation. Due to the relatively small dimensions of the lamp bulb, relatively small and inexpensive magnets may be used.
