This document mainly introduces Agilent 8800 triple quadrupole ICP-MS innovative reaction cell technology, which can effectively eliminate oxide polyatomic ion interference
This document is a compilation of technical posters presented at the Winter Plasma Conference 2012, featuring the Agilent 8800 Triple Quadrupole ICP-MS. The content focuses on the instrument's ability to resolve spectral interferences, specifically oxide polyatomic ions, which often limit detection capabilities in real-world applications.
The MS/MS mode operates the first quadrupole as a 1 amu-window band pass mass filter, selecting only the target mass ions (e.g., m/z 75) and rejecting all other ions such as CoO+.
The MS/MS mode using oxygen reaction gas achieved the best overall reduction of interference, resulting in a measurement of 29 ppt.
