Smoking machine-mainstream flue gas cold trap integrated device and using method thereof

Abstract

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.

Description

technical field

[0001] The invention belongs to the field of cigarette manufacturing research, and relates to a smoking machine-mainstream smoke cold trap collection integrated device and a use method thereof. Background technique

[0002] The mainstream smoke aerosol formed during cigarette smoking is a three-phase coexistence system of gas, liquid and solid, which is divided into two parts: the gas phase and the particle phase. Most of the aroma components in the smoke components exist in the particle phase components, but still a small part exists in the gas phase components. For the collection of mainstream smoke produced by smoking machines under standard conditions, an ideal smoke collection device should meet the following requirements: simple structure; high collection efficiency, quantitative collection; easy to clean; good weight Reproducibility and high reliability; the collected substances should conform to the composition of natural smoke aerosol as much as pos...
