“…Also, reduced sulphur compounds for odour examinations [18,19] and other research of odourous impact assessments [20] were reported. Portable chromatographs like Photovac Voyager -designed to provide near-real time, accurate and precise monitoring of VOC and gases in connection with environmental remediation activities [21,22] -are useful for the fast determination of tetrahydrothiophene in natural gas [23]. They are used for determination of emission from phytoplankton [24] or numerous plant species to the atmosphere [25][26][27].…”

The paper presents the results of the spread of the tetrahydrothiophene (THT) - used as odourant - in the gas network. Such analyses allow quick detection of leaks in networks, systems and devices of gas supply directly to consumers. The main goal of the study was to determine the effectiveness of the use of portable chromatograph and comparing it with a stationary odourant concentration analyser. Based on these studies, an attempt to determine the odouration zone for the selected city have been also taken. For this purpose, three series of measurements were made - in each series 13 points were analysed. Obtained results confirmed the effectiveness of the measurement a concentration of odourant in the gas network using a portable gas chromatograph - difference in relation to the stationary chromatograph ranged from 1.91 to 2.55 %.
