Abstract

The invention provides a dual-mode full-range oxygen-nitrogen-hydrogen analyzer, relates to the technical field of oxygen-nitrogen-hydrogen analyzers, solves the problems of low automation degree and inaccurate analysis of the existing oxygen-nitrogen-hydrogen analyzer, and comprises an electronic balance, an analysis host, a computer and a printer, the analysis host is connected with the computer through a power controller and a gas circuit controller, the analysis host is connected with a cooling-water machine, and the cooling-water machine is controlled through the computer. According to the method, the temperature of a pulse furnace heating device reaches 2000-3000 DEG C, nitrogen in a sample is released, and the percentage content of oxygen and the percentage content of hydrogen in the detected sample are indirectly determined through an infrared hydrogen measurement analysis pool and an infrared oxygen measurement analysis pool respectively; finally, CO2 in the gas is filtered through a CO2 treatment device, the percentage content of nitrogen is determined through a thermal conductivity detection pool, and the analysis accuracy can be effectively improved through automatic control of a gas path system.

Description

technical field [0001] The invention belongs to the technical field of oxygen, nitrogen and hydrogen analyzers, and more specifically relates to a dual-mode full-range oxygen, nitrogen and hydrogen analyzer. Background technique [0002] Oxygen, hydrogen and nitrogen analyzer is an analytical instrument used in the chemical field. It is mainly used for ferrous metals, non-ferrous metals, rare earth metals, inorganic substances, ores, ceramics, etc. in metallurgy, machinery, commodity inspection, scientific research, and chemical industries. Oxygen, nitrogen, hydrogen content analysis in substances. The existing oxygen, hydrogen and nitrogen analyzers have a low degree of automation, and the analysis is not accurate enough. [0003] Therefore, in view of this, the existing structure and defects are researched and improved, and a dual-mode full-range oxygen, nitrogen and hydrogen analyzer is provided in order to achieve the purpose of having more practical value.
