补充资料:X射线谱分析
分子式:
分子量:
CAS号:

性质:根据物质所辐射的X射线光谱以决定它的化学组分的分析方法。将被测物质放在X射线管的阳极上,使发生X射线谱,并测定谱线的波长和强度。这种方法称初级发射X射线谱分析(primary emission X-ray analysis)。或将被测物质放在X射线管内或管外附近,用X射线照射而使受到激发产生荧光X射线谱,再测定谱线的波长和强度。这种方法称荧光X射线谱分析(X-ray fluorescence analysis)。在 一般情况下,比化学分析简单、迅速、方便,并可作定性或定量分析。用于分析元素、钢铁、合金、矿物、石油产品中的硫、液体烃中的溴等。
