Equilibrium studies on colorimetric plastic film sensors for carbon dioxide
Abstract
The equilibrium responses of three new colorimetric plastic film sensors for CO2 as a function of % CO2 and temperature are described. The results fit a model in which there is a 1:1 equilibrium reaction between the deprotonated form of the dye (present in the film as an ion pair) and CO2. The 0-50% and 0-90% response and recovery times of each of these films when exposed to an alternating atmosphere of air and 5% CO2 are determined and in two cases are typically less than 3 s. The shelf life of the films is long (many months); however, prolonged use of the films leads to the permanent generation of the protonated form of the dye over a period of 20-100 h. A possible cause of this latter effect is discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
