Abstract
Disclosed are methods and systems that can detect, monitor, adjust, and optimize fluid dynamic conditions within a sampling system comprising a transport capillary (e.g., an open port interface). The methods and systems detect an acoustic signal within the sampling system and, based on characteristics of the detected acoustic signal, adjust flow rate conditions of the liquid and/or airflow in the sampling system. Also provided are automated control and feedback systems (e.g., automated feedback adjustments made to an inlet pump flow rate, nebulizer gas flow rate, or both) that adjust, tune, and maintain flow conditions within a transport line based on a detected acoustic signal.
