Title Laboratory validation and field verification of a new passive colorimetric air monitoring badge for sampling hydrogen sulfide in air
Bibliographic information Jan. 1984, Vol.45, No.1, p.1-9. Illus. 34 ref.
Abstract This dosimeter has been validated over the range of 1.8 to 164ppm-h (0.23-21 ppm H2S for 8h). Analysis is based on the Texas Air Control Board's molybdenum blue colorimetric method; colour-activated exposed badge solutions are read out on a spectrophotometer set at 580nm and using 10mm cells. The overall accuracy is ▒16%; variations in temperature (10-40░C), relative humidity and face velocity (0.6-76m/s) do not affect badge performance. Unexposed badges are stable for 12 months refrigerated or 2 months at room temperature. Exposed badges can be stored for 1 week at room temperature or 1 month refrigerated. There are no significant interferences from other contaminants.
