Abstract:
1. A system comprising: a tubing arrangement including a first tube surrounded by a second tube, wherein an analyte stream flows through said first tube and exits at a first end thereof, said second tube having a nebulizing gas flowing therethrough that exits said second tube at a second end thereof, wherein at least said second tube is linearly movable with respect to a center axis therethrough; a positioning apparatus configured to linearly adjust a position of said second end of said second tube relative to said first end of said first tube in response to control signals; a mass spectrometer configured to output a signal indicating an ion signal intensity for an ion; and a computing device electrically connected to said mass spectrometer and said positioning apparatus, said computing device configured to receive said signal from said mass spectrometer indicating said ion signal intensity for the ion, to determine, in accordance with said signal, an adjustment to a current position of said second end of said second tube relative to said first end of said first tube, and to send said control signals to the positioning apparatus to linearly adjust a current position of the second tube relative to the first tube in accordance with the adjustment.
