It is equipped with reacting hole 105 up and down positioned at the lower section of reaction film 102 on bottom plate 101, it is anti-convenient for passing through for reaction gas
Film 102 is answered, participates in the reaction of next step, convenient for colour developing, reaction film 102 is through reagent treated test paper in intermediate reaction hole 105
Item is the colour developing core of test strip 100, after being reacted using sample extracting solution with detection reagent, with the presence of sulfur dioxide
When, test strip 100 show aubergine, sulfur dioxide residual quantity number be to be shown by test strips, Test paper
The depth of the color of item 100 and the height of sulfur dioxide residual quantity are directly proportional, and test strips color is deeper, and sulfur dioxide residual quantity is got over
More, 100 detection sensitivity of test strip is good, and accuracy rate is high, and detection limit is low, and experiment front and back color change is obvious, Neng Goushi
The now quick detection to sulfur dioxide or sulfur dioxide residual quantity is illegally added in medicinal material.
As shown in Figure 1, reaction film 102 passes through one layer of 104 gluing of layers of two-sided in the upper table of bottom plate 101 in the present embodiment
Face, layers of two-sided 104 plays the role of fixed reaction film 102, and permeability is good, in this implementation, first on bottom plate 101
Layers of two-sided 104 is first covered, then beats reacting hole 105 again, such reaction film 102 is just capable of fixing the surrounding in reacting hole 105.
As shown in Figure 1, one end of bottom plate 101 is additionally provided with location hole 106 in the present embodiment, location hole 106 plays positioning
Effect, test strip 100 is when being inserted into lid 300, positioning nose end insertion；Besides during detection, instrument is played
The effect of identification, instrument first identifies location hole 106 in measurement, then identifies reacting hole 105.
As shown in Fig. 2, in the present embodiment, in order to allow gas to enough pass rapidly through test strip, the diameter of reacting hole 105
Range is between 4mm-5mm.
As shown in Figure 1, bottom plate 101 uses PVC board in the present embodiment, good supporting role is played.
As shown in Figure 3 and Figure 4, the utility model also proposes a kind of detecting device for sulfur dioxide contained in Chinese herbal pieces, including bottle body
200, lid 300 and the test strip 100, lid 300 is mobilizable to be covered on bottle body 200, and lid 300 is equipped with upper
The detection hole 301 of lower perforation, lid 300, which is equipped with, inserts paper portion 302, and the width direction for inserting paper portion 302 along lid 300 extends, and inserts paper
The inside in portion 302 is equipped with the inserting paper slot 303 for being adapted with the test strip 100 and being connected to detection hole 301, and inserting paper slot
303 one end are equipped with paper insertion port 304, and for the other end for blind hole setting, the upper end face detection hole for inserting paper portion 302 is additionally provided with an air hole
305, air hole 305 is connected with detection hole 301, being inserted in inserting paper slot 303 by will test test strips 100, passing through observation
The color of 100 inside of test strip, compares according to the depth of the color of test strip 100 and standard testing strips item, comes
Semiquantitative determination is carried out to sulfur dioxide residual quantity in sample, it is easy to use, it is easy to operate, it is not necessarily to laboratory profession tester
And detection device, quickly, testing cost is low for detection.
As shown in figure 4, the lower end of lid 300 is additionally provided with the gas-guide tube 307 being connected to detection hole 301 in the present embodiment, lead
The lower end of tracheae 307 gos deep into setting, gas-guide tube 307 in bottle body 200 and plays guidance and buffer function.
As shown in figure 3, the centre of air hole 305 is equipped with divider 306 in the present embodiment, avoids in reaction process and produce
The angry scale of construction is excessive and the case where breaking through test strip 100.
As shown in figure 3, lid 300 is additionally provided with injection orifice 308 up and down in the present embodiment, injection orifice 308 is located at slotting
The side in paper portion 302 can inject reagent into bottle body 200 by injection orifice 308, so that the gas that reaction initially generates can be worn
It crosses test strip 100 to participate in reacting in next step, to reduce detection error.
As shown in figure 3, bottle body 200 and lid 300 all use rubber material, and rubber material is not easy to fall in the present embodiment
It is bad, extend service life.
The principle of the utility model detection sulfur dioxide are as follows: the reaction film 102 of test strip 100 is to contain lead acetate
Test paper, active metal simple substance can restore sulfurous acid in dilute hydrochloric acid or sulphite generates hydrogen sulfide, and vulcanizing Hydrogen Energy makes to soak
Lead acetate paper blackening generate blackspot, according to the depth of blackspot color can in sample sulfur dioxide residual quantity carry out semidefinite
It is fixed to measure.
Detecting step:
1,2 grams of samples are weighed in the balance in specimen cup, are shredded with scissors, are added 10 milliliters of distilled water immersion 10-15 points
Clock；
2,1ml sample liquid (needing 2 pipes with small suction pipe) is extracted in bottle body 200 with liquid-transfering gun, then add 4ml into bottle body 200
Distilled water；
3, lid 300 is covered, and the test strip of wetting 100 is inserted in inserting paper slot 303, then passes through injection orifice
308 inject in bottle body 200 into bottle body 200, shake up；
4, after five minutes observe test strip 100 develop the color situation, sulfur dioxide residual quantity number be by detection try
Paper slip 100 is come what is shown, and test strips color is deeper, and sulfur dioxide residual quantity is more, can also be by the way that compare with colour atla can be relatively accurate
It obtains the content of sulfur dioxide in sample, makees simply, testing cost is low, operates without professional, practical.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Under all utility models in the utility model are conceived, equivalent structure made based on the specification and figures of the utility model
Transformation, or directly/be used in other related technical areas indirectly and be included in the scope of patent protection of the utility model.
