Abstract: Certain configurations described herein are directed to mass spectrometer systems that can use a gas mixture to select and/or detect ions. In some instances, the gas mixture can be used in both a collision mode and in a reaction mode to provide improved detection limits using the same gas mixture.

Abstract: Methods and systems that can use a gas comprising a nitrogen center that is introduced upstream of a plasma sustained in a torch are described. In some configurations, the gas comprising the nitrogen center can be introduced as a gas upstream of the plasma and through a sample introduction device. Mass spectrometers and optical emission systems that can use the gas comprising the nitrogen center are also described.
