摘要: A new Maxxam All-Season Passive Sampling system for monitoring H2S in air has been developed. This passive sampling employs the same approaches as Systems SO2, NO2, and O3 reported previously. extensively tested lab (temperature from -20 to 20 degrees C, relative humidity 30 84%, wind speed 0.5 150 cm/s) validated field studies. Comparing measurements obtained with use of equivalent measurement an active filter pack sampler yielded accuracy greater than 85%. The can be used measure ambient concentrations ranging 0.02 7 ppb based on a 1-month exposure period. There is no significant interference found other sulfur compounds air. many projects.
