原子吸收分析法中的光谱干扰(optical interference),又叫光学干扰:主要有谱线抑制和背景干扰两种,是在光谱发射和吸收过程中产生的干扰。主要的解决方法是减小单色器的光谱通带的宽度,从而使元素的共振吸收线与干扰曲线完全分开,只允许共振吸收线通过;采用抑制或校正背景干扰的方法来减小误差:背景吸收校正( background absorption correction);

First there was the observation by Michelson who back in the late 1880s had done very precise interferal metric measurements of the hydrogen lines and had observed that the 656 nanometer line 3 associated with the transition of n equals 3 to n equals 2 was, in fact, a doublet.
首先是麦克逊,在1880年底的观察,他以公制单位对氢原子的光谱线,作了准确的,无其他因素干扰的,测量,发现当n值由3变为2时,会同时得到波长为656纳米的谱线3,实际上是有两条线。
