The invention relates to the technical field of on-line mass spectrum detection, in particular to a pipeline device for collecting gas phase components in tail gas on line through mass spectrum. Comprising a detection pipeline, an air exhaust pipeline and a quartz capillary tube, the detection pipeline is communicated with the air exhaust pipeline, a diaphragm pump is arranged on the air exhaust pipeline, and tail gas of the detection pipeline is exhausted through the diaphragm pump, so that the flow speed of gas in the detection pipeline is increased; particles with the lower section larger than 1 micron are intercepted; meanwhile, a resistance wire heating layer and a thermal insulation layer are sequentially arranged outside the detection pipeline, the temperature of the detection pipeline is controlled to be lower than the pyrolysis temperature of detection substances, and the pollution problems of instrument pipeline blockage, solid particle tail gas condensation and the like can be prevented; therefore,
