USING A MULTI-CHANNEL X-RAY SPECTROMETER AT A LIME WORKS

SINCE JANUARY 1966 ALL X-RAY FLUORESCENCE ANALYSES OF THE RHEINISCH-WESTFALISCHE KALWERKE, DORNAP, AHVE BEEN CARRIED OUT WITH MRS MULTI-CHANNEL X-RAY SPECTROMETER. ALL THE MATERIALS ASSOCIATED WITH THE MANUFACTURING PROCESS, SUCH AS LIMESTONE, LIME, DRY HYDRATE OF LIME, RAW SLURRY, CLINKER AND CEMENT ARE ANALYZED FOR CALCIUM OXIDE, MAGNESIUM OXIDE, SILICON OXIDE, ALUMINUM OXIDE, FERROUS OXIDE, MANGANESE OXIDE AND SULFITE, WITH A MEASURING TIME OF TWO MINUTES. WITH THE AID OF A DIGITAL COMPUTER INSTALLED AFTER THE EQUIPMENT THE INCOMING IMPULSES ARE CONVERTED INTO PERCENTAGES WHICH ARE PRINTED OUT ON APPROPRIATE FORMS WITH A NUMBER OF CARBON COPIES. PARTICULARS OF THE PROCEDURE ARE REPORTED, & THE AUTHOR DEALS WITH THE PREREQUISITIES TO BE FULFILLED IN ORDER TO ATTAIN A HIGH DEGREE OF ACCURACY, ESPECIALLY THE PREPARATION OF THE SPECIMENS, THE SUPPLY OF ELECTRIC CURRENT AND WATER OF THE EQUIPMENT, AIR- CONDITIONING OF THE WORKING ROOM, AND THE CONSTANCY AND MONITORING OF THE MEASUREMENTS. /AUTHOR/
