Optimisation of DRC ICP-MS for determining selenium in plants
Original language description
An inductively coupled plasma spectrometer (ICP-MS) equipped with a dynamic reaction cell (DRC) was used for determining Se in plant samples. A study was made of the ways of removing polyatomic interferences that affect the determination of the most abundant isotopes of selenium, using CH(4) or, alternatively, NH(3) as a reaction gas. We optimized the efficiency of the bandpass tuning and the cell gas flow rate for suppressing potentially interfering product ions formed by ion-molecule reactions in thedynamic reaction cell of an inductively coupled plasma mass spectrometer. (115)In(+) was selected as an internal standard for determining Se by DRC ICP-MS. We monitored the rate of reaction between (115)In(+) and CH(4) or NH(3), and the product ions created from reactions between In(+) and CH(4) or NH(3). The trueness of the analytical results was assessed by the use of CRMs for Se in plants. The Se experimental results obtained by DRC ICP-MS and by conventional ICP-MS methods were compa
