Description

Technical Field

[0001] The utility model relates to the technical field of ceramic central tubes, in particular to a novel multifunctional ceramic central tube. Background Art

[0002] Inductively coupled plasma spectrometers (ICP spectrometers) utilize information provided by characteristic atomic emission spectral lines for elemental analysis. They offer the advantages of simultaneous, rapid, and direct determination of multiple elements, playing a significant role in industrial production, including metallurgy, petrochemicals, machinery manufacturing, and metalworking. They are one of the most widely used elemental analysis methods in the materials field. However, exciting atomic spectral lines requires a continuous, stable, and powerful electromagnetic field. Currently, the common light source frequencies for ICP spectrometers are 27.12 MHz or 40.68 MHz, with a maximum output power of 1600 W, and sample loading requires a replaceable injection system. First, when the ICP source is operating, the torch coil radiates high-intensity electromagnetic waves. If these waves are not properly shielded, they can significantly interfere with the normal operation of other instrument components, directly affecting the instrument's acquisition and analysis performance and reliability. Therefore, we have redesigned a new, multifunctional ceramic central tube. Utility Model Content
