Description
Technical field
The present invention relates to experimental apparatus technical field, particularly relate to a kind of Electronic Nose sampling device.
Background technology
At present, existing Electronic Nose odor analyses instrument is primarily of sampling operation device and gas circuit flow control system, gas sensor array and signal processing system three kinds of function element compositions.Sampling operation device is equivalent to the nose of people, sensor array is equivalent to olfactory receptor cell, signal processing system is equivalent to people brain composition.
Measure sample when carrying out sampling operation with microsyringe and inject ml headspace bottle, leave standstill balance.When Electronic Nose screen occurs that sample introduction is pointed out, vent wire is inserted ml headspace bottle top and again sample introduction needle is inserted in ml headspace bottle, now instrument auto injection, measure complete preservation experimental data.Will carry out repeated multiple times cleaning to sensor after each measurement, as above repetitive operation measures other samples.
All used ml headspace bottle to be carried out repeated multiple times cleaning after each sample introduction terminates, and careful inspection afterwards, last dry for standby.Need in cleaning process to use a large amount of detersive and special cleaning brush repeatedly to carry out under manpower effect, do not meet the environmental requirement of " Green Chemistry ".And often overlap the special ml headspace bottle limited amount of Electronic Nose, quick detection cannot be realized for a large amount of test sample.In the face of the higher sample of some ageing requirements, existing equipment is long owing to repeatedly cleaning, drying the test period brought, and pole is unfavorable for the continuity of detection, stability and security.
And due to the limitation of sample introduction needle, be merely able to the detection carrying out fluid sample at present, the sample work for the treatment of in early stage of numerous and complicated will be carried out for block, Powdered, paste, the non-fluidic samples such as thread, take time and effort, both the reappearance ensureing experiment had been not easy, cause the raising of testing cost, maintenance workload is large simultaneously.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and a kind of Electronic Nose sampling device of easy and simple to handle, easy cleaning is provided, not only eliminate and repeatedly use detersive and cleaning brush is scrubbed repeatedly and the complex operations flow process such as inspection, and provide effective approach for the variation realizing detecting sample.
The technical scheme adopted for realizing object of the present invention is:
A kind of Electronic Nose sampling device, comprise ml headspace bottle, supporter and plug-in unit, described supporter is placed in described ml headspace bottle, and described plug-in unit is made up of Plug Division and sample portion, described Plug Division and described supporter grafting.
Described supporter comprises hemispherical base and column, and described column is vertically provided with interpolation slit, and both sides, described interpolation slit upper end are symmetrical is respectively provided with at least one holding tank, and relative described holding tank forms one group and clamps described plug-in unit.
The hemispherical base of described supporter adopts soda-lime glass or Pyrex, and the column of described supporter adopts aluminum alloy materials; Described plug-in unit adopts soda-lime glass or Pyrex.
Described sample portion is plate shaped, V-arrangement or shape of container.
Described column and described hemispherical base are Split type structure, described column and described hemispherical base grafting.
Described column and described hemispherical base are integral type structure.
Described sample portion is provided with clamp groove.
Compared with prior art, the invention has the beneficial effects as follows:
1, Electronic Nose sampling device of the present invention is placed with supporter and plug-in unit in ml headspace bottle, sample can be placed on plug-in unit and detect, plug-in unit directly can be discarded upon completion of the assays, ml headspace bottle is rinsed with water, without the need to using detersive and cleaning brush repeatedly to scrub ml headspace bottle and checking in test, easy and simple to handle.Meanwhile, avoid to require the problem such as high to cause because sample is wide in variety, ageing sense cycle is long, experiment poor reproducibility, problem that data reliability is low, improve the reliability of sample detection.
2, Electronic Nose sampling device of the present invention is while solving cleaning problem, overcome the shortcoming that sample introduction is single, traditional liquid material can either be detected, fast sample can also be carried out to on-liquid material (block, Powdered, strip etc.), greatly shorten testing process, cycle, improve detection efficiency.Not only eliminate and ml headspace bottle scrubbed repeatedly and the complex operations flow process such as inspection, be conducive to the protection to environment, and provide effective approach for the variation realizing detecting sample.
3, Electronic Nose sampling device structure of the present invention is simple, compact, and cost is low.
4, Electronic Nose sampling device of the present invention is fixed plug-in unit by holding tank, stable, firmly simultaneously when ensureing that plug-in unit detects sample, can plug and play, easy to use.
5, the plug-in unit in Electronic Nose sampling device of the present invention is small and exquisite, easily join, and cost is low, with after can discard.

Figure 1 shows that the schematic diagram of Electronic Nose sampling device of the present invention;
Figure 2 shows that supporter and the plug-in unit schematic diagram of ml headspace bottle inside;
Figure 3 shows that the schematic diagram of supporter part;
Figure 4 shows that plug-in unit is the schematic diagram of V-shaped.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The schematic diagram of Electronic Nose sampling device of the present invention as Figure 1-Figure 4, comprise ml headspace bottle 1, supporter 3 and plug-in unit 2, described supporter 3 is placed in described ml headspace bottle 1, and described plug-in unit 2 is made up of Plug Division 5 and sample portion 4, described Plug Division 5 and the grafting of described supporter 3.
Supporter can adopt various structures.In the present embodiment, described supporter 3 comprises hemispherical base 8 and column 7, described column 7 is vertically provided with interpolation slit 9, both sides, described interpolation slit 9 upper end are symmetrical is respectively provided with at least one holding tank 6, preferably there are two holding tanks every side, and relative described holding tank 6 forms one group and clamps described plug-in unit 2.
In order to avoid inserter supporter and plug-in unit are on the impact of detected sample detection result, the hemispherical base 8 of described supporter adopts soda-lime glass or Pyrex, and the column 7 of described supporter adopts aluminum alloy materials; Described plug-in unit 2 adopts soda-lime glass or Pyrex.
Per sample state, described sample portion is plate shaped, V-arrangement or shape of container.When sample is liquid, described sample portion 4 is plate shaped, and sample portion and Plug Division 5 form T-shaped; When sample is paste, described sample portion 4 is V-arrangement, and sample portion and Plug Division 5 form Y shape; For when sample is powdery, sample portion 4 for holding the shape of container of sample, as bowl-type etc.
In Electronic Nose sampling device of the present invention, described column 7 can be integral type structure with described hemispherical base 8, also can be Split type structure.When adopting split-type structural, described column 7 and the grafting of described hemispherical base 8.
