采用ICP-AES测定水中氯溴和碘

ICP-OES is a multi-element technique that allows the determination of 75 elements in the periodic table. One element that is desirable to analyze at the same time as other elements is chlorine. However, until recently, the analysis of halogens,especially chlorine, was usually not undertaken by ICP. This was because the halogens are not easy to excite in a plasma source and their emission wavelengths are challenging for conventional optics. Chlorine wavelengths, which yield good sensitivity, are low (133 nm and 134 nm) and are not possible to measure with conventional solidstate detectors or photomultiplier tubes. This Application Note describes recent hardware improvements that allow the determination of Cl,Br and I by ICP-OES. 高性能ICP光谱仪
