Abstract
The present disclosure provides methods and systems for improved detection and/or quantification of selenium (Se) and/or silicon (Si) in samples. In certain embodiment, the methods and systems feature the use of carbon dioxide (CO) as a reaction gas in a reaction cell chamber, such as a dynamic reaction cell (DRC), of an inductively coupled plasma mass spectrometer (ICP-MS). It is found that the use of COas a reaction gas effectively eliminates (or substantially reduces) interfering ionic species for the analytes Se and Si, particularly in samples with complex matrices, and/or in samples with low levels of analyte, thereby enabling more accurate detection of analyte at lower detection limits and in samples having complex matrices.
