In most water disposal, it pay attention to pollution, and color and Ultimate oxygen demand. But, some like Hydrargyrum, Cadmium and other minim-element, because of minuteness content, it has difficulty to inspect. But super-scale minim-element has harm to body's health. In an more and more pollution society, to inspect the minim-element is especially importance.

在处理自来水的过程中，大多只注重了水中的污染物，色度和部分有机物，对于水中含有的各种微量元素，例如：汞，镉，锌等，通常由于其含量微小，而对其进行常规监测有一定的难度，但是微量元素超标对人体健康有着极其的危害，在社会污染日趋严重的今天，对微量元素的监测显得格外重要了。
