Description

Technical Field

[0001] The present invention relates to the technical field of material analysis, and in particular to an inorganic solid material analysis system and method. Background Art

[0002] The content of oxygen, nitrogen and hydrogen in inorganic solid materials such as metals and non-metallic materials is an important factor affecting the performance of materials. Oxidation inclusions, nitrogen alloying and the presence of hydrogen can cause harm. Therefore, testing and analyzing the content of oxygen, nitrogen and hydrogen in materials is necessary for material research, material production quality control and incoming material inspection.

[0003] In material analysis, oxygen, nitrogen and hydrogen analyzers are one of the commonly used equipment for material element detection. They can accurately measure the oxygen, nitrogen and hydrogen contents in various metal and non-metallic solid inorganic materials. The sample is heated at high temperature in a graphite crucible under inert gas protection in an electrode pulse furnace to melt and decompose the sample. The generated carbon dioxide gas is measured by infrared absorption to obtain the oxygen content, the decomposed nitrogen is measured by a thermal conductivity detector to obtain the nitrogen content, and the decomposed hydrogen is measured by an infrared absorption water detector to obtain the hydrogen content. This effectively realizes the accurate determination of the contents of oxygen, nitrogen and hydrogen in one injection. It has now become a mainstream product in the market and is widely used in laboratories such as material research, material synthesis, production enterprise quality control, feed inspection, and product failure analysis.

[0004] Existing oxygen, nitrogen and hydrogen analyzers require operators to manually operate them on site during use, which is time-consuming and labor-intensive, with high labor costs.
