Smoke Testing - Mainstream - Phenolic Compounds
Understand the key constituents of cigarette smoke created once the tobacco is ignited. Mainstream smoke leaves the mouth end of the cigarette after it passes through the tobacco column and filter, and is inhaled by the smoker.
This range of tests provides data for the following constituents of mainstream smoke. Click on each substance tested for further information and interesting facts.

Phenolic compounds These chemicals affect the taste, colour and ‘mouthfeel’ of wine. Phenolic compounds includes tests for the following: - Hydroquinone.
A white granular solid at room temperature and pressure. It is a major component in most photographic developers where it contributes towards the reduction of silver halides to elemental silver. - Resorcinol.
It can be sourced from Brazilwood extract. Resorcinol is used as a colouring agent for certain chromatography experiments and can also be an antiseptic and disinfectant. - Catechol.
A naturally occurring compound used to produce pesticides, flavors, and fragrances. Catechol was first isolated in 1839 by H. Reinsch by distilling catechin; the juice of Mimosa catechu. - Phenol.
Phenol, also known as carbolic acid, is a colourless crystalline solid with a sweet tarry odor, commonly referred to as a "hospital smell". Phenol has antiseptic properties, and was used by Sir Joseph Lister in his pioneering technique of antiseptic surgery during the nineteenth cemtury. It was also used to manufacture Bakelite, one of the first synthetic resins. - m-Cresol, p-Cresol & o-Cresol.
meta-cresol, ortho-cresol and para-cresol. Cresol solutions are used as household cleaners and disinfectants.
