Description
Technical field
The present invention relates to a kind of automatic continuous paper substrate sampling ion mobility spectrometry harvesters.
Background technology
Existing ion mobility spectrometry uses paper as sampling appliance or sucking air as its method of sampling more, to sampling
The ionization method of the sample of acquisition, which generally has, utilizes radioactive source, corona discharge, ultraviolet lamp ionization etc..Mostly paper sampling is to use
One individual disposable or reusable sampling paper wipes sample surfaces, is then detected, after detection
It abandons or cleaning Posterior circle uses.Suction-type detection mode has that accuracy in detection is not high, and partial adsorbates ability is stronger
Surface, target molecule benefit are easily picked up, and cause the false negative situation of detection.
Invention content
To overcome prior art problem, the present invention provides a kind of automatic continuous paper substrate sampling ion mobility spectrometry harvester.

Mouthpiece and sampling paper；
First idler wheel and the second idler wheel are rotationally configured at the ionization in ion mobility spectrometry sampling portion by motor drive
Area both sides, the sampling paper is in closed ring shape, and the sampling paper is placed on first idler wheel and the second idler wheel and by described
First idler wheel and the second idler wheel drive the sampling paper movement, the sampling of forepart between first idler wheel and the second idler wheel
Paper is for acquiring external particles, and the sampling paper at rear portion is used for ion mobility spectrometry between first idler wheel and the second idler wheel
The external particles of the ionized region conveying acquisition in sampling portion, the pyrolysis gas mouthpiece be located at first idler wheel and the second idler wheel it
Between and pyrolysis gas mouthpiece direction towards ion mobility spectrometry sampling portion ionized region.
Preferably, the ion mobility spectrometry sampling portion includes ionized region, ionization door and ion migration zone successively.
Preferably, include tensing described take on the inside of the sampling paper of first idler wheel and the second idler wheel forepart
Sample paper increases the guide post of acquisition external particles area.

Preferably, include detecting the identification device for sampling the paper service life on first idler wheel or the second idler wheel.
Beneficial effects of the present invention：
Automatic continuous paper substrate sampling ion mobility spectrometry harvester provided by the invention simplifies the mistake of sampling and detection
Journey, sampling paper is convenient for changing while same test paper theoretically can realize that low cross contamination may with tow sides using four times
Property, while the reuse of paper is sampled, facilitate the modularization of ion mobility spectrometry consumable component part, simplify the ion mobility spectrometry later stage
It safeguards.
Description of the drawings
Fig. 1 is that the automatic continuous paper substrate of the present invention samples the structure diagram of ion mobility spectrometry harvester.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings：As shown in Figure 1, a kind of automatic continuous paper substrate sampling ion moves
Spectrum harvester is moved, including the first idler wheel 1, the second idler wheel 2, pyrolysis gas mouthpiece 3, sampling paper 4 and guide post 5；
First idler wheel, 1 and second idler wheel 2 is driven, and they are rotatably arranged on ion mobility spectrometry by motor
The ionized region both sides in sampling portion, the present invention are configured at both sides up and down, and the sampling paper 4 is in closed ring shape, is placed on described the
The sampling paper is driven to move on one idler wheel 1 and the second idler wheel 2 and by 1 and second idler wheel 2 of the first idler wheel, positioned at described the
The sampling paper of forepart rolls for acquiring external particles positioned at first idler wheel 1 and second between one idler wheel 1 and the second idler wheel 2
The sampling paper at rear portion is used for the external particles of the ionized region conveying acquisition to ion mobility spectrometry sampling portion, the pyrolysis between wheel 2
Gas mouthpiece 3 is between 1 and second idler wheel 3 of the first idler wheel and the direction of pyrolysis gas mouthpiece 3 is towards ion mobility spectrometry
The ionized region in sampling portion includes tensing the sampling on the inside of the sampling paper of first idler wheel and the second idler wheel forepart
Paper increases the guide post 5 of acquisition external particles area.
The ion mobility spectrometry sampling portion includes ionized region, ionization door and ion migration zone, the material of the sampling paper successively
Expect, to there is the polytetrafluoroethylene (PTFE) of micropore, the identification dress for detecting the sampling paper service life to be included on first idler wheel or the second idler wheel
It puts.
When in use, it is contacted by the outside of the outer surface of ion mobility spectrometry harvester with external environment, surface band
There are the particle or particle of external environment, then 1 and second idler wheel 2 of the first idler wheel rotates, and the sampling paper outside is turned
To the ion mobility spectrometry sampling portion towards inside, the particle on sampling paper is purged by pyrolysis gas mouthpiece 3 and enters ionized region, from
And realize detection, while same sampling paper set also may be reversed, by original lateral surface towards inside, examined again
It surveys.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
It encloses and is defined, under the premise of design spirit of the present invention is not departed from, those of ordinary skill in the art are to the technical side of the present invention
