摘要
对7085内控标准样品进行了均匀性检验和定值,并使用光电直读光谱仪建立了类型标准化法分析7085铝合金的工作曲线,考察了方法的短期精密度和长期精密度,并与电感耦合等离子体原子发射光谱法(ICPAES)分析结果进行数据对比。试验结果表明:选用的内控标准样品均匀性良好,在优化的试验条件下,方法的短期精密度和长期精密度良好,测定结果与ICP-AES分析测定结果相一致,说明方法准确度良好。利用光电直读光谱仪建立的7085铝合金工作曲线分析检测快速准确、仪器稳定,可用于日常分析。
In this research,the uniformity test and the fixed value of 7085 internal control standard samples have been studied.This essay researched the type control sample method to analyze the chemical component of 7085 aluminum alloy by photoelectric direct reading spectrometer.The working curve of type standard and the optimal operating conditions were established.The short term precision and long term precision were studied and the analysis results were compared with the results of ICP-AES.The results showed that the internal control standard samples had good uniformity.Under the optimized experimental conditions,the method have good precision and accuracy.The 7085 aluminum alloy working curve established based on photoelectric direct reading spectrometer analysis can be used for routine analysis.
