Description
Technical field
The present invention relates to a kind of analysis method of cigarette mainstream flue gas total quality feature, specially using highly sensitive
The method that vacuum type Fourier transform infrared spectrometry carries out Direct Analysis to the total quality feature of cigarette mainstream flue gas.
Background technology
Cigarette is a kind of special consumer goods that using effect is reached by sucking, and its performance depends on main flume pair
The sensory effect of consumer.Therefore, the total quality feature of cigarette mainstream flue gas is only studied, and main flow is set up based on this
The integrated evaluating method of flue gas quality, more truly could more fully reflect cigarette product sucks performance and technical characteristic,
It is more conducive to the lifting of cigarette product quality and the research and development of new product.
Main flume can be divided into gas phase and grain phase part, wherein, tar in grain phase part, nicotine, CO content it is larger, one
As trapped and detected using cambridge filter.For gas phase portion, because wherein component is extremely complex, detection difficulty is collected again
Larger, existing capture method can only all be collected into the stable component of some of main flume, it is difficult to catch active middle gas
Body product.So, the research to main flume still stays in offline inspection aspect at present, and can only realize some of flue gas spy
Composition detection and analysis are determined, for example, Liu Jian etc. is established using the means of cold trap trapping-gas chromatography-mass spectrography (GC/MS)
The method of 7 kinds of benzene homologues in simultaneous selection detection gaseous phase of main stream smoke of cigarette thing（Cold trap trapping-gas chromatography-mass spectrography is surveyed
Determine benzene homologues [J] the tobaccos science and technology in gaseous phase of main stream smoke of cigarette thing, 2014,4: 74-78.）；Horse space equality is by changing
Make and be connected smoking machine with APCI-MS ion guns, after cigarette mainstream flue gas is filtered through cambridge filter, gas phase portion is introduced directly into
Analyzed in ion gun.The method for establishing 7 kinds of organic compounds such as acrylonitrile in on-line analysis cigarette mainstream flue gas
（7 kinds of organic compounds by mouth release characteristic [J] tobaccos section in APCI-MS/MS method on-line analysis main flume gas gas-phase objects
Skill, 2014,1: 40-44.）.The foundation for being used as its quality evaluation with constituent part in gas gas-phase objects is clearly to take a part for the whole,
It is difficult to meet the demand that product is precisely assessed.
Infrared spectrum characteristic spectrum is the effective ways for controlling tobacco and tobacco product quality, and infrared spectrum can reflect point
The infrared spectrum of the absorption signal of all major function bases in son, any tobacco and tobacco product molecule all has uniqueness, energy
Reflect the total chemical characteristics of tobacco and tobacco product, one as discriminating tobacco and the tobacco product true and false, and its quality control
Plant effective ways.But infrared spectrum is all only used for liquid or solid for a long time（KBr）Sample is analyzed and evaluated, and is applied to
Carry out that Direct Analysis is also rarely found to gaseous sample, the research of direct global analysis is especially carried out to cigarette mainstream flue gas just not yet
Appear in the newspapers.
