瑞士Testex公司将能量色散型X射线荧光分析装置(EDX)配置到扫描电镜(SEM)中,用于鉴定各种化学元素,评估损失索赔(图1)。该SEM操作简便,能满足不断增长的利用SEM分析羊绒含量的需求,能够显示纤维、长丝和纱线的截面和表面特征。且该SEM的聚焦深度大,分辨率高,特别适合于显示物体 Testex of Switzerland deployed energy dispersive X-ray fluorescence analysis (EDX) devices into scanning electron microscopy (SEM) to identify various chemical elements and evaluate claims for damages (Figure 1). The SEM is easy to handle and meets the ever-growing need to analyze cashmere content using SEM, showing cross-section and surface features of fibers, filaments and yarns. And the depth of focus of the SEM, high resolution, especially suitable for the display object
