摘要： An atomization unit has a tube-shaped furnace, and heats and atomizes a sample injected into the furnace. A light source unit emits light having a wavelength to be measured toward the atomization unit such that light passes through the furnace. An optical system transmits the light having the wavelength to be measured, of light passing through the furnace. A detection unit detects the light transmitted by the optical system. A light transmission plate is provided at a position in an optical path of the light passing through the furnace toward the detection unit, to obliquely cross an optical axis of the light. An image capturing unit is arranged outside the optical path, and captures an image inside the furnace by receiving light reflected by the light transmission plate, of the light passing through the furnace.

摘要： The atomic absorption spectrophotometer is provided with an atomization unit, a light source, a detector, an optical system, a camera, and a captured image data storage unit. The atomization unit has a tube-like furnace and atomizes the sample injected into the furnace by heating the sample. The light source emits light of a wavelength of a measurement target toward the atomization unit so that the light passes through the furnace. The detector detects the light passed through the furnace. The camera captures an image of an inside of the furnace before performing a measurement process in which a sample is atomized in the furnace and its absorbance is measured. The captured image data storage unit stores the captured image data obtained by capturing the image by the camera in association with the measurement data corresponding to the captured image data.

摘要： The object of this invention is to provide an atomic absorptiometer and a metal specimen atomic vapor generation apparatus used in the atomic absorptiometer, which enable a light absorption measurement based on the Zeeman effect highly capable of background correction and eliminate the need for the troublesome work of dismounting a magnet. For this purpose, the following configuration is employed. First, the specimen, hydrochloric acid, and sodium borohydride are delivered and mixed by the peristaltic pump 10 to produce a metallic hydride. The generated gas-liquid mixture solution is separated by the separator 12 into a specimen gas and liquids. The separated specimen gas is introduced into the heating section 30. Electricity is supplied from the power source 28 to the specimen heating section 30 where the specimen gas introduced is heated and separated into hydrogen and a specimen metal vapor to be measured. The specimen metal vapor is then introduced into the measuring section 34 arranged between magnetic poles of the magnet 32 where the metal vapor is subjected to the atomic absorptiometric analysis based on the Zeeman effect.

摘要： A method of analyzing for As(III) as AsO.sub.2.sup.-1 ion in an Au(I) containing electroplating solution. The concentration of As(III) in the electroplating solution is maintained high enough to avoid formation of "burnt Au" oxides but low enough to avoid bond failures. A sample of the electroplating solution is withdrawn and added to a buffered solution, for example an acetate-ethylene diamine tetraacetic acid (EDTA) buffered solution. A complexing agent for Au(I) ion is added to the buffered solution. This can be an alkali metal cyanide. Next ammonium pyrrolidine dithiocarbamate is added as a complexing agent for the AsO.sub.2.sup.-1 ion. The ammonium pyrrolidine dithiocarbamate--AsO.sub.2.sup.-1 ion is extracted, for example with methyl isobutyl ketone (MIBK). The extract is analyzed for As(III) by atomic absorption, as electrothermal atomic absorption spectrometry.

摘要： The manufacturing of a furnace for electro-thermal atomization of samples for spectroscopical purposes having a cavity for the accommodation of sample is simplified and improved. To this end, the furnace consists of two halves which are joined along a separating plane intersecting the cavity. The furnace is made of graphite and provided with a layer of pyrolytic graphite. A platform for the accommodation of the sample is integral with one of the halves. A method for the production of such a furnace comprises the method steps: (a) producing two blank parts which engage each other with planar surfaces; (b) machining the two blank parts in common so that a cavity intersected by the plane of the planar surfaces is generated and each of the blank parts forms one half of the furnace; (c) separating the two halves of the furnace which were produced in this way; (d) coating the halves of the furnace separately, the inner surfaces of the cavity forming outer surfaces of each of the two halves of the furnace; and (e) joining the halves of the furnace, generated in this way, to a furnace. There is also a method described for decreasing the refuse in the manufacturing of the furnaces.

摘要： A method of and a device for multi-element measurement of elements in a sample with correction for background emission. The method starts with atomizing a sample and then exciting the transformed atoms to emit light containing characteristic spectral lines for each element, followed by generating a spectrum of spectral lines characteristic of the elements, followed by measuring the intensity of selected spectral lines falling within a predetermined measuring range without changing their intensity. The next steps are sensing the background emission adjacent the selected spectral lines simultaneously with measuring the intensity of selected spectral lines and determining the concentration of each element from the measured intensity of the corresponding spectral line and sensed background emission.
