Description

Technical Field

[0001] The utility model relates to the technical field of gas chromatography-mass spectrometry, in particular to a gas chromatography-mass spectrometry with a material splitting function. Background Art

[0002] Gas chromatography-mass spectrometry is a mass spectrometer used in medicine and physics. The mobile phase of gas chromatography is inert gas. In gas-solid chromatography, an adsorbent with a large surface area and certain activity is used as the stationary phase. When a multi-component mixed sample enters the chromatographic column, due to the different adsorption forces of the adsorbent on each component, after a certain period of time, the running speed of each component in the chromatographic column is also different. The component with weak adsorption force is easy to be desorbed and leaves the chromatographic column first to enter the detector, while the component with the strongest adsorption force is least likely to be desorbed, so it leaves the chromatographic column last. In this way, the components can be separated from each other in the chromatographic column and enter the detector in sequence to be detected and recorded. Gas chromatography-mass spectrometry can be used for the detection of fragrance chemicals and odor characterization of perfume.

[0003] When existing perfume samples are monitored by a gas chromatograph-mass spectrometer, the samples need to be introduced into the gas chromatograph-mass spectrometer through a loading head, so that they move in the chromatographic column, and then the molecular movement speed in the chromatographic column is measured by a detector to draw chromatographic data.

[0004] However, when the existing device is feeding the mixed sample, because the mixture is not separated, it will cause more inconvenience to the data collection process. Therefore, it is necessary to separate the mixture between the feeding heads so that different mixtures can be separated into various components. At this time, when entering the body for monitoring, the components in the mixture can be better distinguished, which facilitates data collection. Utility Model Content

[0005] The purpose of this application is to solve the existing problems and provide a gas chromatography-mass spectrometer with a material splitting function.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0008] By adopting the above technical solution, when the device is used to monitor the perfume mixture, the mixture is first placed in the storage slot on the storage box, and then the diversion structure is started to rotate the storage box, driving the mixture to rotate, generating centrifugal force, separating the substances in the mixture, and then entering the mixture through the feed head, and the substances in different layers generated after the diversion are detected separately, which allows the device to separate multiple substances during the monitoring process, making the detection of the mixture more accurate.

[0009] Furthermore, the diversion structure includes a diversion motor fixedly connected to the body, the output end of the diversion motor passes through the body and is fixedly connected to the storage box, a sliding column is slidably connected in the storage slot, and the end of the sliding column is fixedly connected to a limiting tooth.

[0011] Furthermore, a limit spring is sleeved on the sliding column, and two ends of the limit spring are respectively fixedly connected to the limit tooth and the storage box.

[0012] By adopting the above technical solution, the limiting tooth moves away from the inner wall of the limiting box through the limiting spring, thereby enhancing the limiting effect of the limiting tooth.

[0018] By adopting the above technical solution, the mixture bottle to be tested is placed along the inclined plate inside the loading tray, and then the driving motor is started to drive the loading tray to rotate, and the inclined plate drives the mixture bottle to rotate.

[0019] Furthermore, a feeding motor is fixedly connected to the machine body, a feeding threaded rod is fixedly connected to the output end of the feeding motor, the feeding threaded rod is rotatably connected to the machine body, the feeding threaded rod is threadedly connected to a feeding plate, a limiting column is fixedly connected to the machine body, and the limiting column is slidably connected to the feeding plate.

[0020] By adopting the above technical solution, the upper motor drives the feeding threaded rod to rotate, so that the feeding plate pushes the mixture to move along the limiting column to the storage slot on the storage box, which enables the device to perform continuous automatic feeding.

[0021] Furthermore, a buffer spring is fixedly connected to the machine body, a buffer plate is fixedly connected to the end of the buffer spring, a limit plate is fixedly connected to the machine body, and the limit plate is adapted to the storage box.

[0022] By adopting the above technical solution, when the bottle body of the mixture is loaded through the loading plate, the bottle body falls on the buffer plate and is lifted by the reset of the buffer spring, making it easier for the loading plate to push the bottle body through the limit plate to the storage slot for loading.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, when the perfume mixture is placed in the placement groove, the limiting teeth are moved away from the inner wall of the limiting box by the limiting spring, so that the two corresponding limiting teeth limit the bottle body containing the mixture, and then the diversion motor is started to drive the storage box to rotate, so that the mixture performs centrifugal motion in the bottle, thereby stratifying the mixture therein, and then the feeding motor is started to drive the lifting threaded rod to rotate, so that the feeding head moves downward along the fixed column until it penetrates into the bottle of the mixture, and then the substances in the bottle are sampled separately according to the stratification of the substances in the bottle, so that the mixture can be divided into different groups according to their different properties and added to the body for detection, which allows the device to better observe the characteristics of different mixtures through diversion during the process of monitoring the perfume mixture, thereby enhancing the detection accuracy of the device.

[0025] 2. In the present application, the mixture bottle to be tested is placed along the inclined plate inside the loading tray, and then the driving motor is started to drive the loading tray to rotate, and the inclined plate pushes the mixture bottle to rotate. As it rotates to the loading plate position, it is pushed into the position of the loading plate, and then the upper motor is started to drive the loading threaded rod to rotate, so that the loading plate pushes the mixture to move along the limit column to the storage slot on the storage box, which enables the device to perform continuous automatic loading, making the device more convenient to use.
