Direct gas chromatographic determination of catechol in cigarette smoke
Tobacco Smoke Research Program, Analytical Chemistry Division, Oak Ridge National Laboratory,Oak Ridge, Tennessee USA
Catechol can be determined as its trimethylsilyl di-ether in total particulate matter (TPM) by direct gas chromatographic analysis of pyridine extracts. The procedure is typically executed with a precision of 2-4% relative standard deviation. The Kentucky Reference (1R1) Cigarette was found to deliver 0.19 milligrams of catechol per cigarette (0.44 weight percent of TPM). The much greater catechol delivery by flue-cured tobacco than burley tobacco was confirmed. The procedure promises to allow the simultaneous determination of nicotine and glycerol.
