“…The Total Particulate Matter (TPM), defined by Rothwell and Grant (1972) as "the fraction of mainstream smoke which is retained by the filter assembly during the smoking process" was evaluated using standard methods of analysis for tobacco smoke. The nicotine and moisture content of the tar residue were determined by gas chromatography using a combination of methods (Schultz and Spears, 1966;Jacin, Slanski and Moshy, 1968;Pillsbury et al, 1969).…”

Summary.-The unusually high relative frequency of cancer in the laryngeal region in males (18% of all histologically diagnosed cancers) and a sex ratio of unity for lung cancer in Northern Thailand were further explored in a hospital-based case-control study in Chiang Mai. This compared patients having cancers of the oral cavity (including oropharynx), larynx, hypopharynx and lung, with controls in relation to smoking and chewing habits. Statistical analysis indicated that chewing betel is strongly associated with the occurrence of oral cancer in both sexes, and with cancer of the laryngeal region in males. No factors were strongly linked to lung cancer in men, but, in women, urban residence and miang cheving were associated with lung cancer. Analysis of smoke from the two main types of cigars smoked in the region showed that both had high tar content, but there were marked differences in pH. Smoking cigars with alkaline smoke and high tar had an increased risk for laryngeal cancer in males, whereas other cigars with acid smoke and high tar together with manufactured cigarettes had increased risks for lung cancer. These increased risks were not, however, statistically significant.MENAKANIT, Muir and Jain (1971) demonstrated a very high relative frequency (18 4%/ ) of cancer's of the laryngopharyngeal region among male cancer cases in Chiang Mai, Northern Thailand. This contrasts with a figure of 3 700 in Bangkok, Central Thailand (Piyaratn, 1959). Although lung cancer has a low relative frequency (< 5%o) in both Chiang Mai and Bangkok, there were far more female cases in Chiang Mai (4-2o% Vs 0 7 o). This is reflected in the male: female ratio of 1-0 in Chiang Mai and 5 0 in Bangkok.The aims of our case-control study were to search for associations between personal habits and cancers of the oral cavity, pharynx, larynx and lung. Attention was focused particularly on smoking, chewing and drinking habits, many of which are different from those in Western populations, especially in older adults. In the laboratory, cigars* from Chiang Mai were compared with Australian-manufactured cigarettes. SmoklingTwo major groups of hand-rolled cigars are smoked in Northern Thailand around Chiang Mai.

“…(d) Nicotine content of fresh tobacco.-Fresh (unsmoked) traditionally processed Northern Thai, and Australian tobaccos were analysed for nicotine, according to the method of Jacin et al (1968), using the solvent system prepared for TPM extraction. The nicotine was determined using the gas chromatographic conditions defined for TPM analysis.…”

Automated Method for Simultaneous Gas-chromatographic Analysis of Nicotine and Water in the Condensate of Tobacco Smoke/Automatisierte gaschromatographische Simultanbestimmung von Nicotin und Wasser im Tabakrauchkondensat

A rapid, automated method for the simultaneous quantitative analysis of nicotine and water in the condensate of tobacco smoke was developed. With the process, it is also possible to quantify the propylene glycol and diethylene glycol, as well as the triacetin contents of the condensate. The apparatus comprises an isotherm gas chromatograph with an automatic injector. A variable split is connected to the injector block, which distributes the sample between two separation columns, as analysis of all substances in a single column does not succeed in a short time. The signals of the two detectors used (thermal conductivity detector and flame ionisation detector) are transferred one after another, time-switched, to an electronic single-channel integrator to be evaluated. With the system described, up to sixty analyses a day are made possible.
