Sharing one ICP source for simultaneous elemental analysis by ICP-MS/OES: some unique instrumental capabilities

Yujia DENG;Xi WU;Yunfei TIAN;Zhirong ZOU;Xiandeng HOU;Xiaoming JIANG

  Inductively coupled plasma(ICP) is one of the most popular sources in analytical atomic spectrometers, including inductively coupled plasma mass spectrometry(ICP-MS) and inductively coupled plasma optical emission spectrometry(ICP-OES). There are several unique independent advantages for either of them. Therefore, a simultaneous elemental analysis system was established as shown in Figure 1. for synergetic work of ICP-MS and ICP-OES by sharing one ICP to improve the analytical figures of merit. To demonstrate its unique utility, several special applications were studied, including correction of interferences for each other, synergetic determination for accurate analysis and combinatorial analysis for larger inear ranges of calibration curves.……
