Abstract

The invention discloses a detection device for enhancing gas detection rate based on a gas-liquid reaction cavity, which comprises a gas-liquid mixing cavity, and a detection gas light source and a detection gas detector which are oppositely distributed are arranged on the side wall of the gas-liquid mixing cavity; the top of the gas-liquid mixing cavity is sealed by a hydrophobic breathable film, and the bottom of the gas-liquid mixing cavity is provided with a gas inlet and a liquid outlet, wherein the diameter of the gas inlet is 0.1 mm to 1.5 mm; the gas inlet is connected with a gas outlet of the gas peristaltic pump through a gas pipeline, and a gas inlet of the gas peristaltic pump is connected with a gas source of sample gas to be detected; the liquid inlet and outlet is connected with one connecting port of the liquid peristaltic pump through a liquid pipeline, and the other connecting port of the liquid peristaltic pump is respectively connected with the plurality of liquid storage devices; and a valve is arranged on a connecting pipeline between each liquid storage device and the liquid peristaltic pump. According to the detection device, the gas-liquid detection speed and the detection sensitivity can be improved.

Description

Technical field [0001] The present invention relates to gas sensors and detection assays environmental technology, in particular, it relates to the detection means based on the reaction chamber to enhance gas-liquid detection rate. Background technique [0002] Volatile organic gases will adversely affect the human body. In order to reduce exposure to harmful gases, there are several mature measurement method, including chromatography, capillary electrophoresis - electrochemical method or the like. [0003] In the aforementioned conventional detection method, since the colorimetric sensor having high sensitivity, good selectivity, low cost, compact, etc., is a promising technique. However, the conventional colorimetric measurement sensors typically require several tens of minutes, testing takes too long and needs to be improved. Inventive content [0004] The present invention provides a liquid detecting apparatus based on the reaction chamber to enhance the rate of gas detectio...
