Abstract
A mass spectrometer is provided that is configurable for operation in both a Kinetic Energy Discrimination (KED) mode and a dynamic reaction cell (DRC) mode. To operate in the KED mode, a collision cell can be filled with a quantity of the inert gas, and an energy barrier can be formed between the collision cell and a downstream mass analyzer. To operate instead in the DRC mode, the collision cell can be filled with a quantity of gas that is reactive with the interferer ions.
