看谱分析是一种利用试样在外来能量激发下产生光谱的特性,进行化学分析的方法。它具有设备简单、操作容易、速度快和灵敏度高等特点,已成为定性分析和鉴别钢铁牌号的有效手段。我厂中心试验室对钢铁中的铬进行了看谱分析,取得了满意的结果。一、实验部分 (一)工作原理被分析物质与电极之间产主电弧或火花,其原子中的电子吸收能量被激发跃迁到高能级,当电子由高能级跃迁回原来的低能
Spectral analysis is a method of chemical analysis that uses the characteristics of a sample that is excited by external energy to produce a spectrum. It has the characteristics of simple equipment, easy operation, high speed and high sensitivity, which has become an effective means of qualitative analysis and identification of steel grades. I plant center laboratory on the steel in the chromium spectrum analysis, and achieved satisfactory results. First, the experimental part (A) Working principle Analyzed material and electrode between the main arc or spark, the electron in its atom absorption energy is excited to transition to high energy level, when the electronic transition from high energy level back to the original low energy
