Embodiment Construction

[0043] In order to make the technical means, creative features, objectives and effects of the invention easy to understand, the present invention will be further elaborated below in conjunction with specific diagrams.

[0044] like Figure 5 As shown, the user operates the electronic control system so that the sample pump and the reagent pump respectively draw a quantitative sample solution and reagent into the measuring instrument, and at the same time, the carrier gas pump draws compressed gas into the measuring instrument. Among them, the sample solution and reagent are driven by the compressed gas and enter the reaction plate through the four-way tube, and the sample and reagent are quickly pushed forward in the coil due to the high-speed flow of the carrier gas (relative to the liquid flow rate). Because of the spiral coil design, the Coriolis force in the liquid flow will make the sample, carrier gas, and reagents rotate and advance in the coil at high speed, forming a s...

Abstract

The invention provides a portable sulfide tester comprising a control device, a liquid path device, a gas-liquid separation device and a photoelectric detection device. The liquid path device comprises a sample injection device and a reaction device which are connected in sequence; the sample injection device comprises a sample pump, a carrier gas pump and a reagent pump, and each pump is connected with the reaction device through an independent channel via a four-way pipe; and the reaction device is selected from a spiral reaction coil, and two ends of the reaction device are respectively connected with the four-way pipe and the gas-liquid separation device. According to the invention, a unique flow path sample injection device and a flow path reaction device are designed, which improvesthe speed of liquid-phase reactants entering a reactor, and ensures than the chemical reaction is more sufficient; a traditional heating step is omitted; the heating effect can be replaced; the chemical reaction is more sufficient; the huge volume of the traditional reaction bottle, acidification blowing and other devices is saved to the maximum extent; and the small-volume portable sulfide testeris designed.

Description

technical field [0001] The invention relates to a gas-phase molecular absorption spectrometer, in particular to a heating-free portable gas-phase molecular absorption spectrometer for sulfide, which belongs to the field of analytical chemical detection. Background technique [0002] Gas Phase Molecular Absorption Spectrometry (GPMAS for short) is based on the principle that the relationship between the light absorption intensity of the gas decomposed into the measured component and the concentration of the measured component complies with the law of light absorption; according to the different absorption wavelengths, Qualitative analysis can also be performed by determining the components to be measured. Gas-phase molecular absorption spectrometry can be used to determine ammonia nitrogen, total nitrogen, sulfide, nitrate nitrogen, nitrite nitrogen, Kjeldahl nitrogen, etc. The detection principle of gas-phase molecular absorption spectroscopy is: firstly, through a chemical...
