Description

Technical Field

[0001] The utility model relates to the technical field of organic matter analysis and detection, in particular to a gas chromatography-mass spectrometry instrument. Background Art

[0002] Gas chromatography-mass spectrometry is an instrument that combines gas chromatography and mass spectrometry technology, which can achieve the separation and analysis of complex organic compounds. In the history of human development, the analysis and identification of substances has always been an important demand. With the advancement of science and technology, people have higher and higher requirements for the analysis and identification of substances, especially in the fields of chemistry, biology, medicine, etc. Traditional analysis methods often have certain limitations and cannot meet the increasingly complex analysis needs. Therefore, people invented the gas chromatography-mass spectrometry, which combines the advantages of gas chromatography and mass spectrometry technology and can achieve rapid and accurate separation and analysis of complex organic compounds.

[0003] The working principle of a gas chromatograph-mass spectrometer is to inject a sample into the instrument through an inlet, and then separate the sample into different components through gas chromatography. These components enter the mass spectrometer through an interface and are then ionized into ions by an ion source. After these ions pass through a mass analyzer, they are separated into different components according to their mass-to-charge ratio. Finally, these components are detected by a detector and output signals, thereby obtaining a mass spectrum of the sample.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. When operating the existing gas chromatograph-mass spectrometer, it is necessary to place the test tube into the instrument for testing. Since the test tube and the instrument are not in the same place, it is extremely inconvenient to take them back and forth, which affects the work timeliness; 2. When the detector is working, the operator needs to label and number the test tube to facilitate the subsequent distinction between different test tubes. Since the label is large in size, it is extremely inconvenient to take and use, and it is easy to slip, causing a lot of trouble to the operator. Utility Model Content
