Abstract
A system embodiment includes, but is not limited to, a syringe pump operably coupled to a desolvation unit, the desolvation unit coupled to a sample analyzer configured to measure an intensity of one or more analytes in a sample solution provided through operation of the syringe pump; and a controller operably coupled to the syringe pump, the controller configured to receive the intensity of the one or more analytes measured by the sample analyzer, determine whether the intensity exceeds a threshold difference of an intensity of at least one standard measured by the sample analyzer, and adjust one or more control parameters of the syringe pump when the intensity of the one or more analytes exceeds the threshold difference to control a flow rate of the sample solution introduced to the sample analyzer.
