自從歐盟實(shí)施RoHS（電子電氣設(shè)備所含特定有害物質(zhì)限制使用指令）環(huán)境法規(guī)以來(lái)，電子電器行業(yè)的有害元素分析變得越來(lái)越重要。X射線(xiàn)熒光光譜能夠簡(jiǎn)單、快速、無(wú)損的分析固體、粉末、液體樣品，被廣泛用作篩選方法。

用能量色散X射線(xiàn)熒光光譜儀（EDX）測(cè)定無(wú)鉛兼容印刷電路板，通過(guò)成圖分析檢出鉛后，還可以確定檢出位置。

X-Ray Fluorescence Spectrometer (EDX-GP)

This instrument irradiates the foreign matter with X-rays and measures the energy of the generated fluorescent X-rays to determine the type and content of the elements comprising the foreign matter. It is extremely effective for the rapid and easy identification of metals and other inorganic substances.
