感应耦合高频等离子体发射光谱法(ICP—AES)是一种多元素同时分析技术。以前,作者及其同事采用去溶装置曾得到较高的检出限。然而,当有大量基体元素共存时,一般都使用不去溶的气动雾化装置,这种装置不仅仍然具有较好的检出限,而且大大降低了第三元素和酸度的影 Inductively coupled high-frequency plasma emission spectrometry (ICP-AES) is a multi-element simultaneous analysis technique. Previously, the authors and their colleagues used the desolventizing device to get higher detection limits. However, when a large amount of matrix elements coexist, aerosol atomizers are generally used which do not dissolve. This device not only still has better detection limits but also greatly reduces the influence of the third element and acidity
