1. A method comprising: receiving a first mode control signal indicating to operate in a first mode; in accordance with the first mode control signal, inputting humidified gas through at least a portion of a conduit to adsorb a layer of water onto an inner surface of the conduit; receiving a second mode control signal indicating to operate in a second mode; in accordance with the second mode control signal, controlling a flow of a gas sample including water soluble contaminants from a source through the conduit to a gas analyzer, wherein the layer of water inhibits the water soluble contaminants from adhering to the inner surface of the conduit; and in response to detecting that a concentration of a particular water soluble contaminant in the gas sample is above a threshold value, toggling between operating in the first mode and the second mode to reduce buildup of the particular water soluble contaminant on the inner surface of the conduit.
