benzene concentration Downloads

Benzene is a naturally occurring com-pound in crude oil and a very useful chemical solvent and feedstock. Unfortu-nately, it can be a signi? cant health risk and is therefore environmentally regulated in many common products especially gasoline. Thus strict limits are put on the concentration and accurate measurements are required. The traditional analytical method for measuring benzene is gas ...
