Phenols (sometimes called phenolics), are a class of chemical compounds consisting of a hydroxyl group (-OH) bonded directly to a benzene ring.


With respect to contaminated land the most common source of phenolic compounds encountered comes from creosote (derived either from wood or coal). the QED hydrocarbon analyser developed by QROS has the ability to quantify and differentiate between these two sources of creosote.


We also offer an on-site technique to quantify general phenolic compounds. The technique will detect and semi-quantify monohydric phenols and some dihydric phenols giving results in the region of ten minutes. The result is equivalent to the standard AAP method for phenol analysis: US EPA method 420.2 (1983) Phenol in water and waste. The reported value is also referred to as the phenol index.
