Description: Sensor arrays were constructed using commercially available heated metal oxide sensors (Figaro TGS2602). These arrays were exposed to several volatile organic compounds (VOCs) in air streams at concentrations levels in the range 0.01–0.30 parts-per-million (ppmv), a range typical of indoor air quality studies. Partial least squares (PLS-2) calibration models were developed using the steady-state sensor array responses. These PLS-2 calibration models were able to detect, differentiate, and quantify different VOCs at concentration typical of indoor environments.
