| titleOfInvention | Personal monitoring device or dosimeter, for measuring exposure of personnel to organic vapors |
| abstract | ABSTRACT OF THE DISCLOSURE A personal monitoring device, dosimeter, or badgelike apparatus for measuring the exposure of personnel to pollutant toxic organic vaporous materials, notably vinyl chloride, comprised of a body portion provided with a relatively shallow top cavity, or cup-like member completely filled with an adsorbent, absorbent or reactive material, preferably activated carbon, covered, closed and physically held in place by a contiguous, thin non-porous membrane, permeable to the organic vaporous materials, notably vinyl chloride. The polluting toxic material, e.g., vinyl chloride, permeats and is trans-ported through the membrane and is then adsorbed on the activated carbon at a rate proportional to the external con-centration during the period of exposure and is subsequently removed for analysis, as by gas chromatography. The device is simple in construction, easy to use, insensitive to tempera-ture and humidity effects, and free of other possible inter-ferences. The device is ideally suited to personal monitoring programs required by OSHA regulations, and the analytical data obtained represents a time-weighted-average exposure which requires no further data evaluations. |
