Sensitive: Several monocyclic aromatic hydrocarbons, for example p-, m-, o-xylene, toluene, and benzene (1–5), were detected in a single measurement by using a planar infrared attenuated total reflection (IR-ATR) fiberoptic sensor that was coated with ethylene/propylene copolymer. Compared to conventional IR sensing systems, this device exhibits a large dynamic detection range.
