Then, shown in Fig. 1 and Fig. 2, this extraction module 40 obtains this determinand b for this formula layer 13 for this food corpse or other object for laboratory examination and chemical testing a certainly, this extraction module 40 includes a heating unit 50 and an extractor 60, this heating unit 50 can be an equipment for heating alcohol, a constent temperature heater etc. at this, and this extractor 60 comprises one and heated and supplied the holding part 61 and of accommodating this food corpse or other object for laboratory examination and chemical testing a to be connected this food corpse or other object for laboratory examination and chemical testing a to be formed to the condensation part 62 of this determinand b with this holding part 61 by this heating unit 50.
This condensation part 62 comprises an importing end 621, one derives end 622, one conduit 623 and a ringwall 624, the bore of this importing end 621 is towards the convergent away from the direction of this holding part 61, in this case stretch among this holding part 61, but not as restriction, also can cover in the outside of this holding part 61, this conduit 623 is communicated between this importing end 621 and this derivation end 622, and have one and make this derivation end 622 reflexed section 6231 down, this ringwall 624 around this conduit 623 and and between this conduit 623, form an annular space 625, the condensing agent c that this annular space 625 must be lowered the temperature for a pair of this conduit 623 of placement, this condensing agent c can be the liquid of a normal temperature, mainly make to form gaseous state by this food corpse or other object for laboratory examination and chemical testing a of this conduit 623, the part that its concentration is not high can be condensed into liquid state fast and be back to this holding part 61, another part that concentration is higher is still held 622 pass-outs for this food corpse or other object for laboratory examination and chemical testing a of gaseous state can form this determinand b by this conduit 623 to this derivation, the bore of this derivation end 622 is towards the convergent away from the direction of this conduit 623.
In this embodiment, this holding part 61 also includes an opening 611, this condensation part 62 also includes a snap close 626 and a soft gasket 627, this snap close 626 is locked on this importing end 621 among this opening 611, this soft gasket 627 is positioned among this snap close 626, and be subject to this snap close 626 to compress this opening 611 of sealing, moreover, in this embodiment, this extraction module 40 also comprises a container 70, this container 70 is equipped with an absorbing agent d, this absorbing agent d can be the solution that is an acidity or an alkalescence, it is this determinand b of gaseous state for being derived by this derivation end 622 in order to collection, this container 70 also comprises the lid 72 of a housing 71 in order to accommodating this absorbing agent d and this housing 71 of sealing, this housing 71 can be transparent at this, in upper and be labeled with a metering scale, this absorbing agent d that so directly the First Astronautic Research Institute for Measurement and Test need be used, and this formula layer 13 that is supplied in this test strip 10 of metering, to detect this determinand b contained in this absorbing agent d.
In sum, because the utility model is by the setting of this extraction module, be able to extract this determinand from this food corpse or other object for laboratory examination and chemical testing, and by the bore of this importing end convergent, and this ringwall can accommodating this condensing agent design, make this food corpse or other object for laboratory examination and chemical testing in the time of extraction, a part that concentration is not high is condensable and reflux, another part that concentration is higher forms this determinand, and there is better extraction efficiency, further shorten the time of detecting, accelerate the underproof food of screening, ensure the safety of popular food, moreover, by this test strip and this detector, make the utility model simply be carried out scene, motor-driven measurement, and need not expend great amount of cost.
Below the utility model is described in detail, but as described above is only a preferred embodiment of the present utility model, when not limiting the scope of the utility model enforcement.Be all equalization variation and modifications etc. of doing according to the utility model application range, all should still belong in patent covering scope of the present utility model.
