Benzene Fenceline Monitoring

Ormantine USA offers reliable and reasonably priced benzene monitoring. We offer our monitoring in two different price ranges and with two different methods.  Our benzene monitors can be pumped or work through diffusion.  We can assist our customers in choosing the method that is the most appropriate for their needs.

Because Ormantine USA specializes in fence line monitoring, we have constructed our tubes from stainless steel to hold up in all weather conditions to prevent your samples from being compromised.

EPA Methods 325A and 325B

The Environmental Protection Agency has issued regulation 325A and 325B requiring all refineries to conduct benzene fence line monitoring. This regulation calls for Passive sampling onto sorbent tubes analyzed by TD-GC/MS as the standard air monitoring technology for the EPA’s proposed rule. Depending on the size of the facility and the distance from the community each refinery will be required to have a specific number of monitors around the facility.

These monitors will be hung around the perimeter of the facility at specific degree intervals from the emission source. After 14 days of exposure the tubes are to be taken down, resealed and sent back to the laboratory for analysis. At that time a new monitor is to be placed in the shelter ensuring continuous monitoring. Please see the regulation for the specifics.
