National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Personal Benzene Vapor Detection Device.

PB93159358

Publication Date	1992
Personal Author	Glatkowski, P.; Druy, M.
Page Count	31
Abstract	A badge was developed as a personal vapor detector to record the cumulative exposure of an individual to benzene (71432) vapor. The badge consisted of an optical fiber, small sections of which were coated with a membrane specific for the adsorption of benzene vapor. Membranes made of polyethylene and nylon, and filled with zeolite were applied to a silver halide fiber. Following exposure, the fiber was subjected to Fourier Transform Infrared (FTIR) spectrometry. The coating successfully retained the benzene vapor for several days. A concentration of 100,000 parts per million (ppm) could be detected. Concentrations of dichlorobenzene (25321226) of 80,000ppm were also detected. Unique absorbance peaks were used to distinguish the two compounds. It was possible to reuse the sensor. However, the desired detectability range of 1 to 100ppm was not met.
