Hydrogel Based-Electrochemical Gas Sensor for Explosive Material Detection
Abstract
In Thailand, most of the bomb devices produced by the terrorists use trinitrotoluene (TNT) as the main explosive material. Detecting TNT and preventing detonation could save many civilians. Due to its low vapor pressure, TNT requires an extremely high sensitivity method for detection. In this paper, we propose an application of the polyacrylamide gel as an electrochemical gas sensor for explosive material detection. Cyclic voltammetry signals were collected from samples, including TNT, pentaerythritol tetranitrate (PETN), and non-explosive vapors. It was found that a time-derivative calculation of the signal was unique to each chemical, rather than the signal itself, demonstrating utility for the detection of explosive material. This approach for making a gel-based sensor and the data analysis looks promising and requires further validation.

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.
