在火焰原子吸收和原子发射光谱方法中,校正操作常常是通过制备一系列组成(分析物和/或共存组分的浓度)呈有规律变化的标准溶液来实现的。这种制备程序是费时的,特别是需要使标准溶液与样品相匹配,或考虑到干扰效应时更是如此。然而每次测量时,每份溶液仅仅只有一小部分被吸入火焰,因此只用一个浓溶液逐步稀释制备标准溶液系列的方法就成为原子光谱技术中具有吸引力的一种方案。 In flame atomic absorption and atomic emission spectrometry methods, calibration is often done by preparing a series of standard solutions whose composition (the concentration of analyte and / or coexisting components) varies regularly. This preparation procedure is time consuming, in particular if the standard solution needs to be matched to the sample or more so given the effect of the interference. However, only a small fraction of each solution is drawn into the flames at each measurement, so the step-by-step dilution of a standard solution series with only one concentrated solution becomes an attractive alternative to atomic spectroscopy.
