Reversibility of colorimetric array response

a, SO2 exposure of the array from N2 to the IDLH (100 ppm) level, and then repeatedly from the IDLH to PEL (5 ppm) and back. b, Cl2 exposure of the array from N2 to the IDLH (10 ppm) level, and then repeatedly from the IDLH to PEL (1 ppm) and back. Data was acquired every min. The response times in this data reflect the dead volume in the gas mixing system and do not represent the intrinsic response of the array (which is shown in Fig. 4). The error bars shown are the standard deviation of triplicate trials.
