Abstract
For the purpose of establishing a conclusive identification method on gas chromatographic analyses of a trace amount of the sulfur compounds in an ambient air, the relative retention times of 33 typical sulfur compounds were measured, as internal standard, diethyl sulfide. The measurements were achieved to compare with the relative retention time of direct injection method into main column (3 mm i. d. 3 m long, phosphoric acid treated glass column) (RtRd) and that of precolumn injection method throughout cooling precolumn (4 mm i. d. 31 cm long, phosphoric acid treated glass column) (RtRp) in liquid oxygen. The polarity of the liquid phase of column packings and column temperatures were also examined.<BR>The ratio of relative retention time, RtRp/RtRd values of 33 sulfur compounds were 0.71.7 in tris (2-cyanoethoxy) propane (TCEP, strong polarity), 0.72.0 in tricresylphosphate (TCP, poor polarity), 0.52.2 in polyphenylether (PPE, poor polarity), respectively.<BR>In general, the RtRp/RtRd values of sulfur compounds even if no effect with increasing of column temperature, but several exceptions were observed, i. e., carbonyl sulfide in TCEP, hydrogen sulfide in TCP, 13 compounds including hydrogen sulfide in PPE..<BR>In conclusion, the estimation of RtRp values from the RtRd values are possible qualitatively.
