Abstract

998,196. X-ray analysis. ASSOCIATED ELECTRICAL INDUSTRIES Ltd., and E. COHEN. July 8, 1963 [July 4, 1962], No. 25673/62. Heading G1A. [Also in Division H1] A liquid suspension of a specimen material required to be analysed is introduced into a hollow cell 5 arranged to constitute with the suspension a composite X-ray tube target such that on energization of the X-ray tube the specimen material in the cell 5 is excited to emit characteristic X-radiation, said radiation being analysed to obtain an analysis of the specimen material. In the arrangement shown the specimen fluid flows into and out of the cell 5 through pipes 6 and 7 respectively and is irradiated by an electron beam 4 from a tube 1 having a filament 2 and a cathode 3. The resulting characteristic X- radiation from the specimen material is analysed by a spectrometer consisting of a collimator 10, a rotatable analysing crystal 11, and a detector 12 which may be rotated about the crystal 11 so that it may be moved to angular positions at which radiation reflection takes place. Alternatively, the detector may consist of a scintillation or proportional counter used in conjunction with a pulse height analyser. In a preferred form the window 8 of the cell 5 may have a layer of a heavier target material such as gold which will produce primary X-rays to excit the specimen material. The layer is so chosen that its own characteristic radiation would not mask that of the specimen. The layer on the window may be discontinuous e.g. in the form of a grid having parallel strip formation (Fig. 4a not shown)
