图4 塑料薄膜对XRF峰域面积的影响 a—使用一系列可用的 XRF薄膜和无薄膜记录的Al峰域面积的比较(使用Mo阳极管在30 kV和30 mA下扫描,计数时间为100 s,引自文献[87]);b—用于XRF岩心扫描仪分析的Ultralene薄膜的透射特性,以及元素 Al、Si 和 Cl 的Kα荧光能量,引自文献[11]

Fig.4 Effect of plastic film on XRF peak areas a—a comparison of recorded Al peak areas using a range of available XRF films and no film (scanned with Mo anode tube at 30 kV and 30 mA, with 100 s count time,cited in [87]);b—transmission properties of the Ultralene foil used for the XRF core scanner analyses, and the Kα fluorescence energies of elements Al, Si, and Cl,cited in [11]
