The invention discloses a smoking
machine-mainstream
flue gas
cold trap integrated device and a using method thereof. The integrated device comprises a
smoke holder, a
cold trap device, a cambridge filter and a single-passage smoking
machine that are sequentially connected by pipelines; the
cold trap device comprises a mainstream
flue gas trap
pipe and is internally provided with a
refrigerant; the mainstream
flue gas trap
pipe is dipped in the
refrigerant; and the mainstream
flue gas trap
pipe is a
quartz pipe of a spiral shape. After the sucking of a cigarette is completed, an
organic solvent is added in the mainstream
flue gas trap pipe and the mainstream
flue gas trap pipe is vibrated sufficiently; the mainstream flue gas condensate is extracted repeatedly; subsequently, the extract is combined; and then the mainstream flue gas sample is analyzed. The method has higher and
safer trap efficiency on the
aroma-
active components in the mainstream flue gas, effectively avoids the generation of various side effects during the flue gas sample treatment process, simplifies the treatment process, shortens time and has higher
repeatability. The method has important application prospect in the fields of analyzing cigarette quality and researching flue gas fingerprints.
