| 摘 要： | 90年代前的各种等离子体光谱仪,受检测器件的限制大都只能用光电倍增管来接收谱能量,不能很好地兼顾分析速度和分析范围。进入90年代,随着微电子技术和电脑技术的飞速发展,美国TJA公司和P-E公司竞相引入了电荷注射阵列检测器(CID)和电荷耦合阵列检测器(CCD),将等离子体光谱仪带入了全谱直读时代。

| Abstract: | Before the nineties the only detector for measurement of spectral lines in ICP-AES was the photomultiplier tube which is not possible to work with both a great speed and wide spectral range concurrently. However, with the development of micro-electronics and computer technology, Thermo-Jarrell Ash Corporation developed charge injection device(CID) and Perkin-Elmer developed charge coupling device(CCD) for use as new detectors in ICP-AES recently. |
