摘要：

The analytical characteristics of a laboratory-scale micro-X-ray fluorescence spectrometer, based on a rotating anode X-ray generator and capillary optics, are described. Usually, a microbeam 15 mu m in diameter, derived from a copper or molybdenum anode operated at 45 kV, is used for sample irradiation. Elemental yields around the 1 count s(-1) (mu g cm(-2))(-1) level are obtained, corresponding to absolute detection limits for thin samples in the 0.05-1 pg range and to relative MDL levels of 3-10 ppm for thick organic samples. The use of the instrument for studying (trace) element migration in Roman glass and for the nondestructive analysis of decorations on Japanese I8th century porcelain vases is described.
