分析化学中最古老的格言之一是,分析只能够好到跟试样一样。同样,在原子光谱法中,分析只能够好到跟试样引入一样。试样引入过程规定了试样通入火焰或等离子体的条件,因而很大程度上决定了分析的准确度。记住了这一点,可以认为在过去10年中试样引入系统在原子光谱法的研究和发展中占据了中心的地位。但是,即使是粗略地比较一下在此期间生产的仪器,也会发现试样引入系统没有同时得到象光学和电子元件那样的进步。因此,以某些严格的基准来看,过去10至15年内进展相当小。例如,无论在检测限或是测定精度方面都没有突破性的改善。此外,未来利用原子光谱法测定“物种形成”的发展过程可能会缩短。在物种形成的研究中,试样引入系统用作色
One of the oldest aphorisms in analytical chemistry is that the analysis is only as good as the sample. Similarly, in atomic spectroscopy, the analysis is only as good as the sample introduction. The sample introduction process specifies the conditions for the passage of the sample into the flame or the plasma and thus largely determines the accuracy of the analysis. With this in mind, it can be assumed that the sample introduction system has dominated the research and development of atomic spectroscopy over the past decade. However, even a rough comparison of the instruments produced during this period shows that the sample introduction system does not achieve the same improvements as optical and electronic components. Therefore, judging from some strict benchmarks, the progress made in the past 10 to 15 years is quite small. For example, there is no breakthrough improvement in both the detection limit and the measurement accuracy. In addition, the future development of “speciation” using atomic spectroscopy may be shortened. In species formation studies, the sample introduction system is used as a color
