Around the year of 2000, some ICP-MS manufactures developed collision/reaction cells (CRCs) so as to cope with this issue. Since then, CRCs have undergone continual refinments and improvement for nearly two decades, and eventually became vital devices in today's quadrupole ICP-MS. In this paper, the latest technological aspects of CRCs are reviewed and their fundamental limitations are clarified. Then follows a discussion about the mechanism for overcoming some of these limitaions by triple quadrupole ICP-MS (ICP-MS/MS). Particulary, this new technology enhances the capability of reaction cells by minimizing the cell-formed interferences and making the mass-shift method truly useful. Many of the interference problems that have remained unresolved for long in ICP-MS are now being resolved. The principles and applications of ICP-MS/MS are described in detail. 收起
