Sulfide analysis system

Abstract

The invention belongs to the technical field of sulfide analysis, and particularly relates to a sulfide analysis system which comprises a gas-phase molecular absorption spectrometer, wherein the gas-phase molecular absorption spectrometer is arranged in the sampling device; the sampling device comprises a driving cavity; driving structures are mounted on the two sides of the driving cavity; the bottom end of the driving cavity is connected with a sampling cavity, the top end of the sampling cavity is provided with an electric push rod, the bottom end of the electric push rod is connected witha sampling piston, the top end of the sampling cavity is connected with a breather pipe, the other end of the breather pipe is connected with a closed cavity, the closed cavity is internally connectedwith a closed piston, and the closed piston is connected with a closed plate. According to the invention, the gas-phase molecular absorption spectrometer is mounted on the sampling device, and then the sampling device is used for sampling and inspecting a water sample in a specific area, so that not only is the operation convenient and rapid, but also the potential safety hazard existing in manual sample extraction can be effectively reduced, and the convenience and safety of sulfide in water during analysis are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of sulfide analysis, in particular to a sulfide analysis system. Background technique [0002] Sulfides in water include soluble hydrogen sulfide, acid-soluble metal sulfides, insoluble sulfides and organic sulfides; usually the measured sulfides refer to soluble and acid-soluble sulfides, and hydrogen sulfide has a strong The smell of rotten eggs, as long as there is a small amount of hydrogen sulfide in the water, it will cause strong discomfort to people. Under the action of bacteria, it will be oxidized to generate sulfuric acid, which will corrode metal equipment and pipelines. Therefore, sulfide is an important indicator of water pollution. [0003] When detecting and analyzing sulfide in water, in order to fully understand the water quality of the water source, it is often necessary to take samples from different areas of the water source for testing.

[0003] When detecting and analyzing sulfide in water, in order to fully understand the water quality of the water source, it is often necessary to take samples from different areas of the water source for testing. At this time, manual sampling is not only time-consuming and laborious, but also has certain risks risk
