[0002] The oxygen and nitrogen analyzer can heat the combustion sample in an inert atmosphere through a pulse heating furnace, and use the pyro-infrared detector IR and the thermal conductivity detector TCD to respectively determine the oxygen and nitrogen content in various steels, non-ferrous metals, rare earths and various new inorganic materials. For the detection of carbon steel, a small part of the body is usually cut and placed in an automatic sampler, and then tested by the set hot melt.

At the same time, the residues will also affect the accuracy of subsequent tests.

[0024] Preferably, the cleaning head 502 is composed of a cylinder and a truncated cone, the bristles 504 at the outer end of the cylinder are vertical, and the bristles 504 at the side of the truncated cone are inclined.
