四、等离子体质谱和辉光放电质谱火花源质谱作为一种体浓度分析技术,虽有许多优点,但也有不少缺点。归纳起来主要有:(1)仪器结构复杂,操作麻烦;(2)采用照相记录,数据处理花费时间;(3)谱线较多,可能引起重叠干扰;(4)不能直接分析溶液;(5)较难得到高精度的定量分析结果。因此,70年代中期以后,许多痕量分析工作逐渐改用等离子体(ICP)发射光谱去完成。但后者
Fourth, plasma mass spectrometry and glow discharge mass spectrometry Spark source mass spectrometry as a body concentration analysis technology, although there are many advantages, but there are many shortcomings. To sum up, there are mainly: (1) the structure of the instrument is complicated and the operation is troublesome; (2) the time is taken to take photographic records and data processing; (3) the more spectral lines may cause overlapping interference; (4) the solution can not be analyzed directly; ) Difficult to get high-precision quantitative analysis results. Therefore, after the mid-1970s, many trace analysis efforts were gradually converted to plasma (ICP) emission spectroscopy. But the latter
