摘要： A method and apparatus for the spectrochemical analysis of a sample in which a solid state array detector (82) is used to detect radiation (62) of spectrochemical interest. The invention involves the use of a shutter (72) adjacent the entrance aperture (70) of a polychromator (74-80) to expose the detector (82) to the radiation (62) for varying lengths of time whereby for short duration exposure times charge accumulation in elements (i.e. pixels) of the detector (82) due to high intensity components of the radiation is limited and for longer exposure times charge accumulation in elements (pixels) of the detector (82) due to feeble intesity components of radiation (62) is increased. This ensures that each reading of the detector (82) includes at least one exposure in which the amount of charge accumulated at each wavelength of interest is neither too little or too great. The problems of feeble radiation components not being accurately measurable and of high intensity radiation components exceeding the charge carrying capacity of elements (pixels) of the detector (82) are thereby able to be avoided. An attenuator (90) may be placed between the radiation source (60) and the detector (82) to permit longer exposure times to be used for very high intensity radiation.

摘要： Spectroscopy apparatus for spectrochemical analysis of a sample having an excitation source (60) for providing spectral light (62) of the sample for analysis. The spectral light (62) is analysed via an optical system (64-66-68) that includes a polychromator (70, 74-80) and solid state multielement array detector (82). The elements (i.e. pixels) of the detector (82) are serially reel by means (84) to provide light intensity measurements as a function of wavelength. A problem is that the elements (pixels) of the detector (82) continue to accumulate change during the serial read-out. This is avoided by providing an optical shutter (72) for blocking the spectral light (62) whilst elements (pixels) of the detector (82) are being serially read. Shutter (72) has a piezoelectric actuator which is preferably a bimorph mounted as a cantilever. It is preferably located adjacent to the entrance aperture (70) of the polychromator. Bimorph structures for the actuator and drive and protective circuit arrangements are also disclosed.

摘要： A method and apparatus for mounting the tubular furnace of spectroscopic apparatus to enable a protective atmosphere. The furnace is supported within the housing by annular electrodes engaging opposite ends of the furnace and an annular chamber surrounds the furnace for substantially its full length. A gas feed chamber adjacent each end of the furnace communicates with the respective adjacent end of the furnace through the central opening of the adjacent electrode and also communicates with the adjacent end of the annular chamber through passages provided in the adjacent electrode. Gas is fed simultaneously from each feed chamber into each end of the furnace and annular chamber to flow axially therealong for discharge through an opening in a wall of the housing located intermediate the furnace ends. According to another aspect, one of the electrodes forms part of a movable door which is operative to open and close one end of the housing chamber containing the furnace, and resilient means acts between that electrode and another part of the door assembly to resiliently urge the electrode against the furnace in the closed condition of the door. According to yet another aspect, the furnace has part-spherical end surfaces for engaging the electrodes and is counterbored at each end to form a raised sample deposition zone.
