Systems and methods for automatic adjustment of mixed gas flow for an injector coordinated with the acquistion of particular groups of chemical elements for analysis

A method for controlling a composition of gas introduced to an analytical system, the method comprising:

• transferring a nebulizer gas to a nebulizer gas port of a spray chamber, the spray chamber further including a gas inlet port to direct one or more matrix gases to an interior of the spray chamber;
• accessing, via a controller operably coupled with the spray chamber, a memory device storing a chemical analysis schedule storing a list of chemical analyses to be performed by the analytical system;
• accessing, via the controller, a memory device storing a gas flow setting corresponding to a next chemical analysis from the list of chemical analyses to be performed by the analytical system;
• and
• regulating a flow of at least a first gas or a second gas to the gas inlet via the controller according to the gas flow setting to coincide with the next chemical analysis.
