Description

Technical Field

[0001] The utility model relates to the technical field of reaction devices, in particular to a quantitative detection reaction device based on air pressure measurement. Background Art

[0002] If the target content to be detected in the closed reaction bottle is different, it will cause air pressure of different intensities. Then, a linear quantitative detection relationship can be established by accurately measuring the air pressure value in the reaction bottle, thereby accurately detecting the target content. For example, platinum nanoparticles can catalyze hydrogen peroxide to produce oxygen, thereby producing an air pressure value reading. Therefore, when the platinum nanoparticle content increases with the target content, the air pressure value in the detection reaction bottle will also increase linearly, thereby achieving quantitative detection of the target. However, when a needle-type syringe is used to inject hydrogen peroxide in a closed reaction bottle system, as long as hydrogen peroxide is injected into the reaction bottle a little, oxygen will immediately be generated in the bottle to generate air pressure, which will cause the remaining hydrogen peroxide to be unable to be injected into it. However, if the amount of hydrogen peroxide added is not enough, then one is that it cannot guarantee that enough oxygen will be produced to be detected by the barometer, and the second is that the speed of oxygen generation slows down, which will all lead to reduced detection sensitivity and inaccurate quantitative detection.

DETAILED DESCRIPTION

The inner bottle cap 2 is inserted on the reaction bottle 1. The reaction bottle 1 is provided with a bottle inner plate 7. The bottle inner plate 7 is provided with a liquid hole 71. The plug column 6 is connected to the inner bottle cap 2. The bottle stopper 5 is provided in the inner bottle cap 2. The plug column 6 is used to seal the liquid hole 71.

At this time, the inner bottle cap 2 is in a tightened state, and the plug 6 blocks the liquid hole 71 to separate hydrogen peroxide from the platinum catalyst. When the target content needs to be detected, the inner bottle cap 2 is rotated in the opposite direction to drive the plug 6 to disengage from the liquid hole 71, and hydrogen peroxide falls into the reaction bottle 7 due to gravity. At this time, the sensor head of the barometer pierces the bottle stopper 5 to perform pressure detection, ensuring that a sufficient amount of hydrogen peroxide reacts quickly with the platinum nanoparticles, so that the barometer can quickly, sensitively and accurately achieve quantitative detection of the target content.
