Benzene

From Guided Wave, Inc.
 

 

Benzene is a naturally occurring compound in crude oil and a very useful chemical solvent and feedstock. Unfortunately, it can be a significant 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 chromatography (GC), which is time and labor intensive. This note will discuss the use of Guided Wave hardware and software tools for the measurement of %Benzene in fuel products using fiber optic-based, Near-Infrared (NIR) spectroscopy. NIR can be applied in real time directly in process monitoring or as a laboratory procedure. In either case NIR is a time and money saving alternative to traditional methods.
