It is an effective means of separating and analyzing complex organic mixtures. During the use of liquid chromatography-tandem mass spectrometry, a fixed seat is required to facilitate the movement of the liquid chromatography-tandem mass spectrometer to a suitable position and ensure the stability of the liquid chromatography-tandem mass spectrometer.

[0003] According to the description of a liquid chromatography tandem mass spectrometer fixing seat disclosed in the patent website (authorization announcement number: CN216646379U), "The utility model discloses a liquid chromatography tandem mass spectrometer fixing seat, which belongs to the field of mass spectrometer fixing seats and solves the problem that it is inconvenient to install a chassis, a body and a mechanical pump on the existing fixing seat. It includes a support table, and four supporting legs are arranged around the bottom of the support table. The top of the support table is provided with a chassis sink for installing the chassis, a body sink for installing the body and a mechanical pump sink for installing the mechanical pump from left to right. The chassis sink, the body sink and the support table at the bottom of the mechanical pump sink are provided with a plurality of threaded holes. A buffer plate is slidably installed in the mechanical pump sink. The buffer plate is provided with a plurality of screw holes corresponding to the positions of the threaded holes. A buffer spring is provided between each of the corresponding screw holes and the threaded holes on the buffer plate.
