Problems solved by technology
However, if the substance to be tested is wet or liquid, it will cause great trouble to fluorescence detection.
Because although fluorescent molecules do not undergo fluorescence quenching reactions with water molecules, water molecules will hinder the propagation of excitation light, causing the detection value to shift, and correct detection results cannot be obtained

The invention discloses a method and a system for detecting whether a gas to be tested contains water molecules. The method comprises the following steps: step 1, selecting n detecting points in a gasdetecting channel and providing fluorescent molecules on the first detecting point; step 2, transmitting the light whose wavelength is the first wavelength to the first detecting point on the gas detecting channel, and respectively transmitting the light whose wavelength is the second wavelength to the second detecting point,..., and the nth detecting point on the gas detecting channel; step 3, after the gas to be tested enters the gas detecting channel through a gas inlet of the gas detecting channel, respectively collecting the light intensity variation curves of the light, whose wavelengthis the second wavelength, of the n detecting points, and acquiring the first light intensity change curve, the second light intensity change curve,..., and the nth light intensity change curve; and step 4, determining whether the gas to be tested contains water molecules based on light intensity decrease information and light intensity recovery information which are indicated by the first light intensity change curve, the second light intensity change curve,..., and the nth light intensity change curve.
Description
technical field [0001] The invention relates to the field of gas detection, in particular to a method and a device for detecting whether a gas to be measured contains water molecules. Background technique [0002] At present, when the gas is detected, if the gas contains water molecules, accurate detection results cannot be obtained. [0003] For example, for the detection devices currently on the market based on the reaction principle of fluorescent polymer molecules or fluorescent self-assembled small molecules, when sampling, most of them use a wipe to wipe the substance to be tested, and then detect it. However, if the substance to be tested is wet or liquid, it will bring great troubles to fluorescence detection. Because although fluorescent molecules do not undergo fluorescence quenching reactions with water molecules, water molecules will hinder the propagation of excitation light, causing the detection value to shift, and correct detection results cannot be obtained...
