【摘要】 <正> 原子光谱分析中的标准加入方法通常用于补偿被测试样基体产生的影响,手工操作时要多次加入已知量的标准物到被测试样中,费时费样。流动注射进样技术和原子光谱分析相结合,在很大程度上可以克服一般的标准加入法操作的繁琐,降低试液的消耗,提高分析结果的准确性。Tyson提出的内插式标准加入法是把试样溶液当作载流,把进样更多还原

【Abstract】 Three FIA standard addition calibration methods for ICP spectroscopy were evaluated in this paper. The precision and recovery of three methods were compared. The capabilities to compensating different matrix effects were discussed in detail.更多还原
