Electrode protrusion adjustment for maximizing pressure drop across liquid transport conduit

A method of adjusting a position of a tip of an electrode relative to an end of a nebulizer nozzle of a mass spectrometry device, the method comprising:

• providing a conduit and the electrode connected to the conduit at a first end of the conduit, wherein the electrode tip is disposed at a first position relative to the nebulizer nozzle end;
• connecting a pressure gauge to a second end of the conduit opposite the first end;
• initiating a gas ejection from the nebulizer nozzle with the electrode tip at the first position;
• during the gas ejection, adjusting the position of the electrode tip from the first position towards a second position relative to the nebulizer nozzle end;
• and
• terminating adjusting the position from the first position towards the second position based on a pressure condition displayed by the pressure gauge, wherein upon terminating adjusting the position from the first position towards the second position, the electrode tip is at the second position.
