Problems solved by technology

Among these detection standards, except that the detection of carbon monoxide can be carried out simultaneously with the nicotine moisture in cigarette smoke and the detection can be completed, the detection of the other 6 harmful components needs to be collected separately in a smoking machine, and then use different detection instruments The process of detection and analysis is slow, and the steps are repeated and cumbersome. Only in the part of smoking supplementation of the smoking machine, the detection of 6 harmful components needs to be repeated 6 times of cigarette smoking. It is a big disadvantage, and it has been unable to meet the current industry needs of fast-paced detection and analysis.

Embodiment 1

[0053] 1. Detection device

[0054] The device used in the detection method in this embodiment is as follows ( figure 1 ):

[0055] Smoke trap 2 and solvent trap bottle 4 ( figure 2 ) is sealed and connected through the connecting pipeline 3; the solvent trapping bottle 4 is sealed and connected with the suction unit 6 through the connecting pipeline 5; a blank filter is loaded in the smoke trap 2; 50mL deionized water is installed in the solvent trapping bottle 4.

[0056] One end of the connecting pipeline 3 is sealed with the smoke trap 2 , and the other end is inserted into the deionized water in the solvent trap bottle 4 .

[0057] One end of the connection pipeline 5 is sealed to the suction unit 6 , and the other end is communicated with the solvent trapping bottle 4 .

[0058] In the device of the present invention, the smoke catcher 2 is the smoke catcher of the smoking machine, and the suction unit 6 is the suction unit of the smoking machine, which is equivalent...

Embodiment 2

[0077] According to the detection method described in Example 1, a kind of cigarette B is selected, and the amount of carbon monoxide released in smoke is measured to be 13.1 mg / support, the amount of NNK released is 4.2 nanograms / support, the amount of phenol released is 15.6 micrograms / support, and the amount of crotonaldehyde released 18.0 micrograms per bottle, 8.9 micrograms of ammonia released per bottle, and 146.2 micrograms of hydrogen cyanide released per bottle.

Embodiment 3

[0079] According to the detection method described in Example 1, a kind of cigarette C is selected, and the amount of carbon monoxide released in smoke is measured to be 13.5 mg / support, the amount of NNK released is 4.8 nanograms / support, the amount of phenol released is 11.8 micrograms / support, and the amount of crotonaldehyde released 18.7 micrograms per bottle, ammonia release of 6.8 micrograms per bottle, and hydrogen cyanide release of 125.9 micrograms per bottle.

Abstract

The invention discloses a method for quickly measuring harmful ingredients in main stream smoke of a cigarette. According to the method, solvent gathering and filter disc gathering are adopted on a smoking machine at the same time, carbon monoxide is detected through a non-scattering infrared detection on the smoking machine, a solvent is used for gathering ammonia, hydrogen cyanide and crotonaldehyde, a filter disc is used for gathering NNK, ammonia, hydrogen cyanide and phenol, and after being collected, samples are detected through efficient high oerformance liquid chromatography, ion chromatography and a liquid chromatogram/gas chromatograph-mass spectrometer. The method integrates six tobacco industry standard methods for harmful ingredient detection in smoke of the cigarette, operation is easy and convenient, the analysis procedure is simplified, the analysis step of repeatedly smoking the cigarette is avoided, precision is good, and the method is suitable for measuring the content of the harmful ingredients in the main stream smoke of the cigarette.

Description

1. Technical field [0001] The invention relates to a detection method, in particular to a method for rapidly measuring harmful components in mainstream smoke of cigarettes. 2. Background technology [0002] In recent years, the topic of smoking and health has been widely concerned by people, and it has been generally recognized that smoking is harmful to health. The detection methods for harmful components such as NNK, phenol, crotonaldehyde, ammonia, hydrogen cyanide, benzopyrene and carbon monoxide in cigarette smoke have also become mature, and national and industry standards have been formed. At present, both the research and development of analytical instruments and the improvement of analytical methods are moving towards the goal of saving analysis time and human resources. Among these testing standards, except that the detection of carbon monoxide can be carried out simultaneously with the nicotine moisture in cigarette smoke and the detection can be completed, the d...
