Based on above-mentioned, described carrying body to support one or more in the molecular sieve of chemical reagent, resin, silica gel or glass fabric.
This human exhaled breath's alcohol concentration test agent application in testing human expiration alcohol concentration.
When described human exhaled breath's alcohol concentration test agent runs into containing spirituous expiration, alcohol oxidation can be become acetaldehyde rapidly by oxygenant wherein in acid condition, and then be oxidized to acetic acid, and the manganese ion of high-valence state or chromium ion are reduced into manganese ion or the chromium ion of lower valency, its color also can change pink into by aubergine thereupon or change green into by orange-yellow.
This human exhaled breath's alcohol concentration test agent is seated in disposable expiratory alcohol concentration test device for human body, region containing test agent, the length of its color change is directly proportional to alcohol concentration in expiration, accordingly, can according to the length of test agent field color change, whether the concentration differentiating alcohol in exhaling or the concentration differentiating alcohol in expiration exceed standard.
Hinge structure of the present invention has outstanding substantive distinguishing features and significant progressive, specifically has following advantage: liquid chemical challenges is attached in carrying body, have structure simple, easy to use, be beneficial to the advantage popularized; Adopt chemical method testing human expiration alcohol concentration, the reaction time is short, and colour developing obviously, contrasts with scale mark and can facilitate, judges test result intuitively; The proving installation of this human body expiration alcohol concentration determination agent is housed, can uses within the scope of 0 ~ 50 DEG C, stable storing, can long-term storage, adapt to the use of most occasion.
Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
A kind of human exhaled breath's alcohol concentration test agent, it is made up of oxygenant, salt and acid, wherein, the mass ratio of described oxygenant, described salt, described acid is 1:0.3 ~ 1:20, the concentration of described acid is massfraction 20 ~ 70%, described oxygenant is one or more in chromium trioxide, potassium permanganate, potassium dichromate or potassium chromate, and described salt is one or more in magnesium nitrate, magnesium sulfate, silver sulfate or silver nitrate, and described acid is one or more in nitric acid, sulfuric acid or perchloric acid.
In the present embodiment, potassium permanganate selected by described oxygenant, and magnesium nitrate selected by described salt, and nitric acid is selected in described acid.
The preparation method of aforementioned human exhaled breath's alcohol concentration test agent, it comprises the following steps:
Step 1, described oxygenant, described salt, described acid fully to be mixed with appropriate water in proportion, make liquid chemical challenges; In the present embodiment, be specifically the ratio mixing of 1:0.3:20:40 in mass ratio by potassium permanganate, magnesium nitrate, nitric acid and water, make liquid chemical challenges.
Step 2, granular carrying body is dipped in described liquid chemical challenges, mix at 30 ~ 80 DEG C, and constantly stir 10 ~ 60 minutes, then filter, wherein, described carrying body to support one or more in the molecular sieve of chemical reagent, resin, silica gel or glass fabric.
