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.

Devices and Methods to improve background equivalent concentrations of elemental species

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.

Systems and methods using a gas mixture to select ions

The present disclosure provides methods and systems for automated tuning of multimode inductively coupled plasma mass spectrometers (ICP-MS). In certain embodiments, a 'single click' optimization method is provided for a multi-mode ICP-MS system that automates tuning of the system in one or more modes selected from among the multiple modes, e.g., a vented cell mode, a reaction cell mode (e.g., dynamic reaction cell mode), and a collision cell mode (e.g., kinetic energy discrimination mode). Workflows and computational routines, including a dynamic range optimization technique, are presented that provide faster, more efficient, and more accurate tuning.
