摘要： An air sampling system and method are provided to collect air samples from a plurality of air sample inlets. Before or after transmitting an air sample originating from one of the sample inlets, a signal gas is transmitted via the sample line in accordance with one of a plurality of predefined burp patterns, each of which uniquely corresponds to a different one of the sample inlets. The sample line is monitored for the signal gas in accordance with the predefined burp patterns. Based on detection of the signal gas in the sample line in accordance with one of the predefined burp patterns, a related action is taken. The related action can be identifying the sample inlet from which the air sample originated, or further transmitting the air sample via the sample line.
