Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency infrared carbon-sulfur analyzers, in particular to an automatic sampler for a high-frequency infrared carbon-sulfur analyzer. Background Art

[0002] A high-frequency infrared carbon-sulfur analyzer is a detection device that combines an external carbon-sulfur analyzer with a high-frequency induction combustion furnace for quickly and accurately detecting the carbon and sulfur element contents in samples. The working principle of the high-frequency infrared carbon-sulfur analyzer is that the test sample is oxidized to form CO2 and SO2 under high-temperature and oxygen-rich conditions in the high-frequency induction combustion furnace. The change in the light intensity after the infrared light is absorbed by the CO2 and SO2 gases is detected by the infrared detection cell, and the CO2 and SO2 contents are inversely calculated, so as to indirectly obtain the carbon and sulfur element contents in the measured sample.

[0003] In the existing high-frequency infrared carbon-sulfur analyzers, most samples are manually placed into the analyzer, which is likely to cause the crucible to tip over and the sample to be omitted, thus generating analysis errors.

[0004] In view of this, in order to study and improve the existing problems, an automatic sampler for a high-frequency infrared carbon-sulfur analyzer is provided. The crucible is driven by a motor to rotate the lead screw and enter the analyzer main body, and the crucible is driven by an electric push rod to enter the experimental chamber to complete automatic sampling. The purpose is to solve the problems and improve the usability through this technology. Content of the Utility Model
