The effects of the carrier and intermediate gas flow rates, height of observation and power on REE spectral line intensities have been studied by a orthogonal design The influence of interference elements which conclude matrix and other analyte was investigated. 采用正交设计法研究了载气及等离子气流量、观察高度和功率对稀土谱线强度的影响。考察了基体元素以及其它稀土元素对待测稀土元素的干扰。
Lummer_Gehrcke plate and prism spectrometer is used to get interference fringes of some wavelength spectral line. The data of the interference fringes are read with charge coupled device ( CCD), and then the width of the spectrum can be got immediately. 介绍了运用鲁末&盖格板及棱镜光谱仪得到某一波长谱线的干涉条纹,用CCD拍摄和计算机处理,能快捷地得到该谱线宽度的方法。
The spectral line ( S 181.972 nm) in the ultraviolet ragion was selected for the determination to prevent the interference of large amounts of calcium in the matrix. 测定中选择了在紫外区的谱线(S181.972nm)作分析线可有效地避免了基体中大量钙的干扰。
Among them the spectral line management system was written in Foxbase, the interference recognition and calibration and interference correction systems were written in Quick BASIC. 该系统包括谱线管理系统、识别干扰程度系统、校准及干扰校正系统、帮助系统等子系统。
Character of spectral line with B element, and its spectral interference were studied In condition without separating interference element and filling N, ICP AES method was adopted to determine trace element B in high temperature alloy 研究了硼元素光谱线的特性及其光谱干扰,建立了不须分离干扰元素和不充氮条件下,直接测定高温合金中微量硼元素的ICPAES法
