A Rapid EDXRF Method of Simultaneous Quantitative Elemental Analysis Using an Annular Cd-109 Source

Volume 41, Number 5 (July 1987) Page 906-908

Recent EDXRF studies of Chinese ceramics of the Ming (1368-1644) and Qing (1644-1911) dynasties, the Republic period (1912-1939), and the modern period (after World War II) have given encouraging results for the identification of modern fake reproductions and the attribution and dating of Chinese porcelains. However, quantitative elemental determination requires tedious calibration procedures. In general, a separate calibration curve is required for each element to be determined, and, when one is using Cd-109 sources, quantitative elemental determination (say from Mn to Nb) would be rather time-consuming.
