PASSIVE DEVICE FOR THE DETECTION AND/OR DETERMINATION IN SITU OF AMINES IN GASES

A sensor for the detection and/or determination in situ of amines in air, such as atmospheric air, is obtained by means of a direct, easy and reproducible synthesis consisting in soaking the derivatisation agent sodium 1,3-naphthoquinone-4-sulfonate (NQS) in polydimethylsiloxane (PDMS). It has been...

Beschreibung
Zusammenfassung:	A sensor for the detection and/or determination in situ of amines in air, such as atmospheric air, is obtained by means of a direct, easy and reproducible synthesis consisting in soaking the derivatisation agent sodium 1,3-naphthoquinone-4-sulfonate (NQS) in polydimethylsiloxane (PDMS). It has been shown that the device can detect amine concentrations of 3 mg/m 3 in 5 hours. Both the device and its response to the presence of gamines remain stable over time. In addition, no external source is required for detection (i.e. it is a passive sensor that allows gamines to be detected by means of visual inspection), requiring zero energy cost and having no toxicity, since both the NQS and the PDMS are non toxic.
