前言近年来,利用能谱技术对固体表面特征的研究已有文献报导,文献对工业氨合成催化剂还原态表面组成进行了分析,定量观察了催化剂表面元素分布的不均匀性。PHI595型多功能探针综合了扫描俄歇电子微分析,扫描电子显微技术和x射线能量分析仪器的优点和能力,它具有一个独特的细束高电流的电子枪,利用它研究催化剂的表面特征,可给出一个真实的三维表面分析,给出各元素的立体分布特征。
Preface In recent years, the use of energy spectrum analysis of solid surface features have been reported in the literature, the literature on the industrial ammonia synthesis catalyst reduction of the surface composition was analyzed quantitatively observed the catalyst surface element distribution inhomogeneity. The PHI595 Multipurpose Probe combines the advantages and capabilities of scanning Auger electron microanalysis, scanning electron microscopy and x-ray energy analysis instruments with a unique beam-high current electron gun that can be used to study the surface characteristics of a catalyst , Can give a real three-dimensional surface analysis, given the three-dimensional distribution of the elements.
