Molecular absorption spectrometer adopting gas-liquid separation membrane

Abstract

The invention relates to a molecular absorption spectrometer adopting gas-liquid separation membrane. The molecular absorption spectrometer adopting gas-liquid separation membrane comprises a reactor and a detector, wherein a gas-liquid separation membrane is installed in an inner cavity of the reactor, and the inner cavity of the reactor is divided by the gas-liquid separation membrane into a first reaction cavity and a second reaction cavity; the first reaction cavity is communicated with an inner cavity of the detector by virtue of a conveying pipeline; the second reaction cavity is connected with a sample feeding apparatus and a gas carrier apparatus; the detector is provided with a light source and a detection apparatus capable of receiving light emitted by the light source. By adopting the molecular absorption spectrometer adopting the gas-liquid separation membrane, after a water sample to be detected reacts with a reagent in the reactor, water in gas generated by the reaction can be directly filtered by virtue of the gas-liquid separation membrane; and moreover, the gas-liquid separation membrane is disposed in the reactor, so that a reaction apparatus is combined with a drying apparatus, the system is greatly simplified, the device is simple to operate, the miniaturization and convenience in carry of instruments can be facilitated, the sample to be detected can be determined on site, and the application range of the instruments can be enlarged.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, and specifically designs a molecular absorption spectrometer using a polymer gas-liquid separation membrane. Background technique [0002] Water resources are the most important natural resources for human beings and the basic conditions for human survival and development. In recent years, with the increasingly serious pollution of water resources, water quality monitoring, as a basic work in water pollution control, provides scientific basis for water environment management, pollution source control, environmental planning, etc. Environmental health plays a vital role. [0003] There are many water quality analysis index items, and the detection methods are also different due to different uses. Gas-Phase Molecular Absorption Spectrometry (GPMAS) is based on the principle of Beer-Lambert Law (Beer-Lambert Law) based on the gas concentration and characteristic light absorption i...
