Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of couplings, in particular to a coupling for a triple quadrupole liquid-mass spectrometer. Background Art
[0002] Triple quadrupole LC-MS is a high performance liquid chromatography-mass spectrometry technology that integrates a triple quadrupole mass spectrometer and a high performance liquid chromatograph, and connects the two through an interface component. During the analysis process, the sample is separated by a high performance liquid chromatography column and then enters the mass spectrometer for ionization, detection and analysis. The instrument has the advantages of high sensitivity, high resolution, and high selectivity, and can quickly and accurately detect and quantify a variety of compounds in complex samples; a coupling is a mechanical transmission element used to connect two shafts together to transmit torque and rotational motion. It can connect two shafts with different axes or the same axis so that they can rotate together and transmit torque, while allowing certain axial, radial and angular offsets.
[0003] In the current field of mechanical transmission, the design and application of couplings face diverse demands, especially in precision instruments and complex mechanical systems. Traditional coupling designs are often limited to two basic types: rigid or elastic. Each design has its specific application scenarios. For high-precision analytical instruments such as triple quadrupole liquid-mass spectrometers, elastic couplings are usually preferred because they can effectively reduce vibration and compensate for axial, radial and angular deviations, thereby ensuring the stability and accuracy of the instrument during operation. However, under certain specific operating conditions or environmental restrictions, rigid couplings may also become a more appropriate choice. However, the current coupling replacement process is time-consuming and labor-intensive, which not only interrupts the normal operation of the instrument, but also increases maintenance costs.
