【Abstract】 In order to build a method of tetramine detection, capillary column of gas chromatography was applied. Condition of the method was as follow: a flame photometry detector, a optical filter of sulfur, a semi-polar capillary column, programming temperatures: initial temperatures 210℃, then raised to 240℃ at speed of 10℃/min, keeping the temperature for 5min, temperature of injector 250℃, temperatures of detector 260℃. The results showed that detection limit was 1.5×10 -10 g.s -1 . RSD of the precision was 0.59%. RSD of the repeatability was 1.6%. the detection range was 10-200ng. 8 organic sulfides didn t disturb the detection. Thus, the method was suitable for tetramine detection.更多还原
