Example Embodiment

[0030] The present invention will be further described in detail below in conjunction with the drawings.

[0031] See figure 1 , The present invention includes two gas cylinders 1, which are equipped with gas sources required for the experiment; each gas cylinder 1 is provided with a gas source pressure reducing valve 2, and the two gas source pressure reducing valves 2 are simultaneously connected to the gas flow controller 3. ; The gas flow controller 3 is connected to the tubular heating furnace 4, the gas flow meter 5, the gas collection device 6 and the chromatographic mass spectrometer 8 in sequence.

[0032] See figure 2 with image 3 The tube heating furnace 4 includes a furnace body 11 and an inner tube 15 arranged inside the furnace body 11. A furnace mouth for taking out the inner tube 5 is opened on the side wall of the furnace body 11, and a furnace cover 12 is provided at the furnace mouth for easy removal The inner tube 15 is filled with tobacco samples; a heating ...

Abstract

The invention relates to a large-capacity heat-not-burn tobacco product simulated experimental analysis apparatus and method. The apparatus comprises a gas bottle, a valve, a tubular heater, a gas flowmeter, a gas collector and a gas chromatograph-mass spectrometer which are connected in sequence. The tubular heater comprises comprises a furnace body and an inner tube arranged in the furnace bodyand the furnace body is provided with an opening for people to take out the inner tube; a heating device is arranged between the furnace body and the inner tube; the front inlet of the inner tube is connected with the gas bottle through the valve, the rear inlet of the inner tube is connected with the flowmeter, and the inlet and the outlet of the inner tube are both higher than the bottom thereof. The apparatus has the advantages that stable temperature control is achieved, the sample injection volume can reach 100 g, different heating modes can be simulated, and with the open design, secondary cracking due to factors such as closed environment and pressure can be avoided effectively, gaseous hydrocarbon and residues obtained after thermal cracking can be collected respectively, off-linesample injection can be carried out, high sample capacity can be achieved, and analysis and research on minor components can be facilitated.

Description

technical field [0001] The invention belongs to the field of tobacco analysis, and in particular relates to a large-capacity heat-not-burn tobacco product simulation experiment analysis device and method. Background technique [0002] New tobacco products are emerging strategic products of the tobacco industry, and the development of new tobacco products is a major strategic issue related to the future development of the industry. As the market demand for new smokeless tobacco products grows rapidly and more and more tobacco manufacturers are committed to the research and development of new and less harmful tobacco products, as a representative new smokeless tobacco product, only heating and not burning Type low-temperature tobacco products began to receive more and more attention. The so-called heat-not-burn low-temperature tobacco products refer to the method of heating shredded tobacco at low temperature instead of burning shredded tobacco to generate smoke, which can re...
