Description

Technical Field

[0001] The utility model relates to the technical field of spectrometers, in particular to a spark direct-reading spectrometer. Background Art

[0002] Spark direct reading spectrometer is a rapid quantitative analysis instrument for analyzing the composition of ferrous and non-ferrous metals. It is widely used in metallurgy, machinery and other industrial sectors for online analysis before smelting furnaces and product inspection in central laboratories. It is one of the effective means to control product quality.

[0003] When analyzing the sample, the analysis surface of the sample is placed downward on the spark table to cover the excitation hole, and the lower electrode excites and analyzes it. The excitation spot formed by the electrode on the sample is small when the sample is placed downward, and the excitation hole is much larger than the excitation position. It is difficult to accurately determine the analysis position by placing the sample based on experience or feeling. For samples such as welds that need to be accurately analyzed in a very small area, it is not easy to analyze at an ideal position based on experience and feeling. The sample needs to be prepared and analyzed repeatedly, which brings many inconveniences and waste of resources. Moreover, for spherical or cylindrical test samples with arc-shaped ends, it is difficult to place the test sample stably on the spark table, resulting in the inability to detect such test samples, affecting normal detection. Therefore, a spark direct-reading spectrometer is designed to solve the above problems. Utility Model Content
