| 光电直读光谱仪激发系统： Excitation system of photoelectric direct reading spectrometer: （1）高能预燃低压火花激发光源+高纯氩气激发气氛：采用高能预燃，大幅降低了样品组织结构对原子化结果的影响 (1) High energy precombustion low pressure spark source + high purity argon atmosphere: the influence of sample structure on atomization results is greatly reduced by using high energy pre combustion （2）高压火花激发光源+高纯氩气激发气氛：采集光强不稳定 (2) High voltage spark source + high purity argon atmosphere: unstable light intensity （3）低压火花激发光源+高纯氩气激发气氛：对同一样品光强稳定，但是对于样品组织结构对原子化的影响无能为力 (3) Low pressure spark source + high purity argon atmosphere: the light intensity of the same sample is stable, but it is powerless for the influence of sample structure on atomization （4）直流电弧激发光源+高纯氩气激发气氛：对样品中的痕量元素光谱分辨率和检出限有好效果。 (4) DC arc excitation light source + high purity argon atmosphere: it has good effect on the spectral resolution and detection limit of trace elements in samples. （5）数控激发光源+高纯氩气激发气氛：按照样品中各元素的光谱特性，把激发过程分为灵活可调的几个时间段，每段时间只针对某几个情况相近的元素给出最佳的激发状态进行激发，并仅采集这几个元素。把各元素的激发状态按照试验情况进行分类讨论） (5) Numerical control excitation light source + high purity argon excitation atmosphere: according to the spectral characteristics of each element in the sample, the excitation process is divided into several flexible and adjustable time periods. In each period, the best excitation state is given for some elements with similar conditions, and only these elements are collected. The excited states of each element are classified and discussed according to the test conditions.) |
