Abstract
Preliminary feasibility data toward the development of a pocket size personal monitor for glutaraldehyde (111308) vapor were collected. Surface Acoustic Wave (SAW) chemical microsensors were used as the detector. Five different materials were investigated for their effectiveness as glutaraldehyde sensitive coatings on a 250 megahertz SAW resonator device. Several different polymer coated SAW resonators were found to reversibly detect glutaraldehyde vapor at concentrations in the 5 to 17 parts per million range. The best coating investigated was fluoropolyol which exhibited a sensitivity of almost 80 hertz/mg/m3 of glutaraldehyde. The sensors typically showed an initial response to glutaraldehyde vapor in less than 30 seconds. A dinitrophenylhydrazine coated SAW microsensor was studied and found to offer highly sensitive but anomalous responses to glutaraldehyde. The author concludes that the results of the study provide critical information needed for the continued design of a pocket sized Personal Exposure Monitor (PEM) for glutaraldehyde vapor. The authors suggest that it is likely that the same approach used for this glutaraldehyde PEM could be successfully used to develop PEMs for many other toxic vapors.
