A DC electrical discharge was used to obtain information on the presence of gaseous species (e.g. argon) inside a laboratory model of a double-pane window. The relative concentrations of additive gases (e.g. argon) were measured using the optical emission in the spectral region from near ultraviolet to near infrared (NIR). The amount of argon in air can be determined using our method with a precision of 10% at low concentrations and approximately 5% at moderate to high concentrations.
