Description
Technical field
The present invention relates to a kind of analytical equipment of cigarette smoke gas chemistry composition, a kind of online and real-time analysis device that is used for single port cigarette smoke gas phase composition of more specifically saying so.
Background technology
Cigarette smoke is the main sign that cigarette product satisfies the needs of consumers, and is the main factor that embodies cigarette quality level and style and features.Therefore, the cigarette smoke chemical composition analysis is a crucial research work, also is one of key element of constructing the cigarette core technology.
Cigarette smoke also is a kind of very complicated chemical mixture simultaneously, and up to now, people have therefrom identified several thousand kinds of materials.Usually, in order to study conveniently, people adopt cambridge filter that flue gas is divided into granule phase substance matter and gaseous substance two parts, and wherein room temperature condition can partly be called as gaseous substance by the flue gas of cambridge filter down, can be called as granule phase substance matter by the part that cambridge filter intercepts.The proportion of the shared flue gas total amount of gaseous substance mainly contains nitrogen, oxygen, carbon dioxide, carbon monoxide and hydrogen up to 92%, comprises volatile hydrocarbon, ester class, furans, nitrile, aldehyde ketone, alcohols or the like in addition; Granule phase substance matter account for the flue gas total amount less than 8%, mainly form, wherein the complex mixture formed by oxide, sulfide and the nitride etc. of multiple hydro carbons and hydrocarbon again of tar by water, nicotine and tar; In addition, also have the material of some intermediate forms, as the acid of some half volatiles and aldehyde material etc., they exist in the gas of flue gas, grain two-phase simultaneously.
Traditional flue gas analysis method is to adopt the off-line type analysis mode to carry out basically, promptly earlier flue gas is captured, and adopts different pre-treatment processes then as required, analyzes with different instruments again.Yet, many studies show that, bringing out the fresh main flume that comes from cigarette filter during aspirating is high concentration, highly active gasoloid, its inner material is formed among the dynamic process that is in a continuous variation.Thereby, traditional flue gas analysis method is owing to will relate to complicated analytic process such as sampling, separation, purifying and derivatization, can cause the aging of flue gas, and in the sampling and analysing process, also may introduce artificial material, thereby make its analysis result be difficult to reflect truly the flue gas situation in the smoker oral cavity.So, want exactly the single port cigarette smoke to be carried out online and real-time analysis from the scientific methods that the angle of chemical composition is analyzed and estimated cigarette smoke quality, style and features and fragrance component and objectionable constituent.
Because tar attitude cigarette smoke granule phase substance matter is easily in the pipeline of smoking machine and the inside deposition of analytical instrument, and when analyzing, be difficult to effective removing, directly it detected, can cause qualitative, especially quantitative analysis results is extremely inaccurate.Therefore, from the report of present documents and materials, it is the emphasis of all kinds of on-line analysis researchs that the cigarette smoke gaseous component is analyzed, and technological means such as infra-red sepectrometry and vacuum ultraviolet ionized mass spectroscopy have been applied to this alanysis.
Infra-red sepectrometry is a kind of quick, harmless analytical approach, since Philippe in 1956 and Hobbs are applied to infra-red sepectrometry cigarette smoke first and analyze, this method in the research fresh smoke chemical reaction and the analysis of flue gas gaseous component in obtained using widely.But, carry out qualitative because infra-red sepectrometry is the specific absorption wavelength according to compound to component, thereby for the flue gas system of complexity, this method can only be analyzed the specific target substance of minority wherein, and the reliability of its quantitative analysis results is also not really desirable.
Vacuum ultraviolet ionized mass-spectrometric technique is a kind of very outstanding, pervasive and detection means fast, it uses vacuum UV lamp, laser or synchrotron radiation light as the ionization light source usually, can carry out ionization to organic compound in the mode of soft ionization, almost only produce the parent ion of determinand, and do not produce fragment, so this technology is very suitable for the research of complex mixture.In recent years, people such as Mitschke (Mitschke S, Adam T, Streibel T, et al.Application oftime-of-flight mass spectrometry with laser-based photoionization methods for time-resolvedon-line analysis of mainstream cigarette smoke.Anal Chem, 2005,77 (8): 2288-2296.) adopt first with laser do light source vacuum ultraviolet ionized mass-spectrometric technique on-line analysis single port cigarette smoke chemical constitution.This technology has that response speed is fast, selectivity is high (spectrum and mass spectrum double selection) and advantage such as suitable polycomponent detection.Commercial smoking machine flow of flue gas pipeline is long, and inwall often adheres to the smoke components of abundant residues but people such as Mitschke find, thereby the quantitative analysis results of following a bite flue gas is brought very big interference; In order to eliminate interference, humans such as Mitschke self-control smoking apparatus replaces commercial smoking machine, and manually extract cigarette in per two mouthfuls of flue gases suction gap and prop up, utilize the mode of suction air that remaining flue gas is removed, but still the residual disturbing effect of bringing that can't well remove smoke; In addition, the employed self-control smoking apparatus operation of people such as Mitschke is loaded down with trivial details, is mainly used in fundamental research, can't carry out the detection of continuous and automatic to cigarette smoke; And, consider that international flue gas suction mode all uses commercial smoking machine, use the self-control smoking apparatus to be unfavorable for that each laboratory compares to the flue gas analysis result.Therefore, its concrete application has been subjected to great limitation.
