Sequential Air Sampler System: Its Use by the Virginia Department of Highways & Transportation

Report No: 75-R33

Published in 1975

About the report:

The Department of Highways & Transportation needs an economical and efficient air quality sampling system for meeting requirements on air monitoring for proposed projects located in critical areas. Two sequential air sampling systems, the ERAI and the EMI, that appeared to be the answer to this need were evaluated. On the basis of analytical reliability, the EMI system Is far superior to the ERAI; while on the basis of design, the ERAI Is slightly better. Since the availability of reliable air quality data Is a far more important consideration than system design, it is recommended that the Department use the EMI sequential sampler system, after suitable modification of the system enclosure for better security.
