A method and system are provided for detecting the concentration of an anaiyte in a fluid sample. The method and system involve analysis of a volatilized, ionized fluid sample using a mass spectrometer or other ionic anaiyte detection device that provides a signal proportional in intensity to the quantity of ionized anaiyte detected. The improvement involves replacement of a necessary non-analyte component in the fluid sample with a substitute component that serves the same purpose as the original component but is either more volatile than the original component and/or the anaiyte or undergoes a reaction to provide lower molecular weight reaction products, and results in an increased intensity in signal and signal-to-noise ratio. Acoustic fluid ejection is a preferred method of generating nanoliter-sized droplets of fluid sample that are then volatilized, ionized, and analyzed.
