Abstract
The performance of passive colorimetric dosimeter tubes for carbon- monoxide (630080) (CO) was studied in a series of tests using both dry and humid conditions. Tubes from three different manufacturers were evaluated. Tubes were exposed to CO at 25, 50, 100, and 400 parts per million (ppm). Relative humidities were maintained at less than 20 or over 80 percent during the tests. The flow dilution system used in this study consisted of a dilution air stream, a contaminant air stream, and an exposure chamber. CO at known concentrations was entered into the exposure chamber. The passive dosimeters were tested in an exposure chamber designed to assure uniform CO concentrations for all samples at adequate face velocities under test conditions. The tests indicated that the overall performance of the colorimetric dosimeter tubes for CO determination was satisfactory for only one of the three makes tested. Humidity had a statistically significant effect on the performance of these tubes. Dry conditions produced a higher response. The CO dose readings overestimated the measured values at higher concentrations and underestimated them at lower concentrations. Concentrations of about 100ppm gave the best accuracy. The authors suggest that the user of such tubes check the accuracy with in/house calibrations.
