Stain length passive dosimeter for monitoring of carbon monoxide
A new passive dosimeter for the personal monitoring of CO exposure in the workplace has been developed. This new type of sampling device does not require follow-up analysis of the collected sample to determine the exposure. Rather, the time-weighted average concentration is determined directly from the length of a coloured stain which is produced instantaneously during the exposure period in a specially prepared indicator tube. The stain length is a function of both contaminant concentration and exposure time. The effects of CO concentration in the range 0.5-2.0 x TLV on the response of the dosimeter were evaluated in a dynamic exposure chamber. Data were fitted to the appropriate model equation with a correlation coefficient of 0.968. By eliminating the need for follow-up analysis, this stain-length dosimeter significantly reduces the cost of monitoring.
