Colorimetric, stain length, personal dosimeters operating by gas diffusion have been developed to determine worker exposure for up to an eight-hour period for several inorganic airborne contaminants in the range of their Threshold Limit Values. Length of stain, colorimetric dosimeters have been made for the detection of ammonia (NH3), carbon monoxide (CO), carbon dioxide (CO2), hydrogen sulfide (H2S), nitrogen dioxide (NO2), and sulfur dioxide (SO2) in air. For each gas detection system, the sampler depends on the transfer of the gas by diffusion into a glass tube containing a colorimetric length of stain indicator. The stain length developed in a given period of time is compared to a calibration chart to determine, on the spot, the average gas concentration to which the dosimeter has been exposed. These dosimeters are known by the trade name Vapor Gard.
已经开发出通过气体扩散操作的比色、染色长度个人剂量计，以确定工人在长达八小时的时间段内对几种处于其阈限值范围内的无机空气传播污染物的暴露情况。已经制造出用于检测空气中氨（NH₃）、一氧化碳（CO）、二氧化碳（CO₂）、硫化氢（H₂S）、二氧化氮（NO₂）和二氧化硫（SO₂）的染色长度比色剂量计。对于每个气体检测系统，采样器依靠气体通过扩散转移到一个装有比色长度染色指示剂的玻璃管中。将在给定时间段内形成的染色长度与校准图表进行比较，以当场确定剂量计所暴露的平均气体浓度。这些剂量计的商品名为Vapor Gard。
