摘要： An absorption profile indicative of a relation in atomic absorption spectroscopy between the absorbance of a desired element and time has a constant half-width independent of the concentration of the desired element in a sample, and hence the half-width of absorption profile with respect to the desired element can be previously determined from data which is obtained by the measurement of a standard sample. In an atomic absorption spectrophotometer herein disclosed, the half-width of absorption profile is previously determined in the above-mentioned manner, and the true peak value of an absorption profile obtained by measuring a sample which contains the desired element at a high concentration, is calculated using the time width of this absorption profile at a predetermined absorbance and the previously-determined half-width.

摘要： An ampoule shaped electrodeless discharge tube, including a large-diameter portion and a small-diameter portion, is filled with luminous elements and inactive gas. The discharge tube is placed in a housing having a lighting window from which the light emitted by the elements is extracted. A high-frequency coil is wound around the large diameter portion at the middle portion of the discharge tube. A partition wall provided in the housing partitions the housing into a first and a second compartments. The middle portion of the discharge tube and the small diameter portion are placed in the first compartment, while the end portion of the discharge tube opposite to the small-diameter portion is placed in the second compartment, and is cooled with air-flow flowing from the inlet to the outlet, both of which are formed to the housing. When high-frequency power is supplied to the coil, the luminous elements in the discharge tube is excited to luminesce. The light thus emitted is extracted to the exterior, through the lighting window. Unvaporized elements are localized at the portion to be cooled by the air-flow.
