Between, be all connected by latex tube between II grade of cold solvent trapping bottle and smoking machine.
Smoking machine associated with this utility model can be single channel smoking machine, straight line smoking machine, carousel-type smoking machine etc. no
With type smoking machine, and can be the most used in parallel at multiple passages of linear type smoking machine, aspiration procedure can be according to GB/
T 16450-2004 or ISO3008:2000 standard are aspirated, i.e. single port pumping volume is 35mL, and suction time is 2s, suction
Being spaced apart 58s, aspiration procedure controls syringe pump by a computer precision and realizes.During cigarette smoking, granule phase substance retains
At cambridge filter, flue gas gas phase composition is captured in one-level cold solvent absorption bottle and two grades of cold solvent absorption bottles.Due to this practicality
Being inverted buchner funnel shape bottom novel cold solvent capturing device air inlet pipe, internal diameter is increased to 12-15mm by 6-8mm,
And bottom is that (GB/T 27523-2011 regulation device then uses bottom absorption bottle as pore sphere structure, hole count G0 core sieve plate
Less than 20, and aperture is 2-3mm macropore, and therefore the contact area of flue gas stream and trapping solution is relatively limited), thus effectively
Improve the contact area of flue gas stream and solution, it is achieved that to the trapping completely of different boiling component in gas phase.Use this master
Stream flue gas gas phase composition capturing device can effectively trap fresh smoke, have that arresting efficiency is high, pre-treating method operation quickly, weight
The advantage that renaturation is good, is simultaneously suitable for the polytype smoking machines such as straight line smoking machine, single channel smoking and rotating disk smoking machine,
On smoke perfume component analysis, analysis of volatile components, there is significant application value.

The chromatograph of a little representative target compounds responds the block diagram of (normalized) as shown in Figure 3, Figure 4: for volatility chemical combination
Thing (Fig. 3), the chromatograph response that two kinds of devices obtain there was no significant difference；For the boiling point half volatile compound (figure more than 100 DEG C
4) the chromatographic peak abundance that, this utility model device obtains is significantly higher than GB/T 27523-2011 regulation device.
Embodiment 3
It is sequentially connected with 3 cold solvent absorption bottles of the present utility model to be attached, is used for trapping gaseous phase of main stream smoke of cigarette
Composition.Three absorption bottles all use 35mL cold solvent absorption bottle, and trapping solution volume is 10mL, and trapping solution is methanol solvate
(the deuterated benzene containing 200 μ g/mL, deuterated pyridine, phenethyl acetate mixing internal standard).Smoking machine uses straight line smoking machine, and Cambridge is filtered
Sheet is 44mm diameter, uses modeling effusion meter that gas flow is adjusted to 35mL/s.The trade mark 2 cigarette sample will be extracted, according to GB/
T 16447-2004 standard gauge fixed condition carries out Sample equilibration, selects (average quality ± 0.02) g and (average resistance to suction ± 50) Pa
Cigarette for sample test, under the conditions of standard aspiration, trap 10 components in cigarette smoke gas phase compositions.After suction terminates, by the 3rd
In level cold solvent absorption bottle, trapping solution takes 2mL solution in chromatogram bottle, uses and carries out GC/MS detection.GC/MS detection method is same
Embodiment 1.
The SIM figure of the 3rd absorption bottle is as it is shown in figure 5, as shown in Figure 5: in chromatogram in addition to having internal standard peak, there is no
Other compound peaks, illustrate that the series connection absorption bottle using this experimental provision can trap all target gas phase compounds completely.
