Description

Technical Field

[0002] Essential oil is a kind of liquid with fragrance extracted or distilled from flowers, leaves, wood and other animals and plants. The produced essential oil needs to be tested for various components in the essential oil. The existing detection of essential oil usually uses a gas chromatograph for detection. With gas as the mobile phase, the essential oil sample is injected into the injector. After the sample is instantly vaporized, the mobile phase gas carrier gas carries the sample and passes through the chromatographic column equipped with a stationary phase. Because the component molecules and the stationary phase molecules inside the chromatographic column undergo adsorption, desorption and dissolution, components with similar chemical properties have a great separation effect. The separated components enter the detector system in sequence, and the detector converts them into electrical signals and sends them to the recorder or integrator to draw a chromatogram.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1-Figure 11As shown, the present invention provides: component detection equipment and a component detection method for essential oils, including a detection body 1, a pipetting component 3, a chromatographic column protection component 6 and a chromatographic column body 8. The detection body 1 is the main structure of the entire device, which is used to accommodate and fix other components, provide a stable working environment, and ensure the normal operation of the device. A controller 2 for controlling the operation of the device is provided on one side of the outside of the detection body 1, and the controller 2 is used to display the test results on a display screen thereon, which is used to display the test results and the operation interface. The controller 2 receives user instructions, such as starting, stopping, adjusting parameters, etc., and controls the operation of the device according to these instructions. At the same time, it also receives data from the detection body 1, such as temperature, etc., and displays it on the display screen. Through the controller 2, the user can conveniently operate the device and monitor the detection process in real time. A chromatographic column body 8 is arranged inside the detection body 1, and a chromatographic column protection component 6 is also arranged inside the detection body 1. The chromatographic column protection component 6 includes a chromatographic column protection ring 61. The chromatographic column protection component 6 is used to protect the chromatographic column body 8 to prevent the chromatographic column body 8 from being damaged due to excessive bending due to its own gravity. The chromatographic column body 8 is the core component of chromatographic analysis, and is usually composed of a tubular structure filled with a stationary phase (such as silica gel, alumina, etc.). The sample to be detected is separated and adsorbed in the chromatographic column, thereby realizing the separation and detection of different components.

[0033] The chromatographic column protection ring 61 is formed by splicing two semicircular structures. The inner walls of the two chromatographic column protection rings 61 are provided with chromatographic column limiting grooves 66. The chromatographic column limiting grooves 66 are spirally coiled in the chromatographic column protection rings 61. The chromatographic column limiting grooves 66 cooperate with the chromatographic column body 8. The chromatographic column body 8 is stuck in the chromatographic column limiting grooves 66. The chromatographic column limiting grooves 66 are used to protect the chromatographic column body 8 to prevent the chromatographic column body 8 from being bent and damaged by its own gravity for a long time. The chromatographic column protection ring 61 cooperates with the chromatographic column body 8 through the chromatographic column limiting grooves 66 inside it, and the chromatographic column body 8 is firmly stuck in the chromatographic column limiting grooves 66. In this way, even if the chromatographic column body 8 is affected by its own gravity, it will not bend or deform too much, thereby protecting the chromatographic column body 8 from damage. At the same time, the spirally coiled limiting grooves can also improve the stability of the chromatographic column to a certain extent.

[0034] In this embodiment, a spiral chromatographic column limiting groove 66 is arranged inside the chromatographic column protection ring 61, and the chromatographic column limiting groove 66 corresponds to the chromatographic column body 8, and the chromatographic column protection ring 61 is formed by splicing two semicircular structures, so that the chromatographic column body 8 is coiled in the chromatographic column limiting groove 66, and then the two semicircular structures are fixed by bolts, and the chromatographic column protection ring 61 is pushed into the detection body 1 to complete the installation, so that the chromatographic column protection ring 61 protects the chromatographic column body 8, effectively prevents the chromatographic column body 8 from bending or breaking due to gravity, and also effectively prevents the chromatographic column body 8 from being damaged by external force.

[0035] The chromatographic column protection assembly 6 also includes a slide rail 63, and a plurality of slide rails 63 are provided in the detection body 1, and the slide rails 63 are respectively fixed on the upper wall and the lower wall of the detection body 1, and a slider 62 is slidably provided on the slide rail 63, and the slide rail 63 has a smooth surface and a precise guide structure, which is used to ensure that the slider 62 can slide steadily and smoothly thereon. When the chromatographic column protection ring 61 needs to be installed or removed, the slider 62 slides along the slide rail 63, thereby driving the chromatographic column protection ring 61 to move. This design makes the installation and removal process of the chromatographic column protection ring 61 simpler and faster. The slider 62 is fixedly connected to the chromatographic column protection ring 61, and the chromatographic column protection ring 61 is slidably connected on the slide rail 63 through the slider 62, which is convenient for installing and removing the chromatographic column protection ring 61.

[0036] The chromatographic column protection assembly 6 also includes a limiting member 64 and an elastic clip 65. The limiting member 64 is installed on both sides of the chromatographic column protection ring 61, and the elastic clip 65 is fixed to the inner side of the detection body 1 by bolts. The inside of the elastic clip 65 is arc-shaped, the limiting member 64 is arc-shaped, and the limiting member 64 and the elastic clip 65 cooperate with each other. When the chromatographic column protection ring 61 is installed in place, the limiting member 64 is inserted into the elastic clip 65, and the elastic clip 65 fixes the limiting member 64 to prevent the chromatographic column protection ring 61 from sliding on its own.

[0037] When the stopper 64 is inserted into the elastic buckle 65, due to the elastic effect of the elastic buckle 65, it will tightly embrace the stopper 64 to form a stable fixed structure. In this way, the chromatographic column protection ring 61 is firmly fixed in the detection body 1 to prevent it from sliding or moving on its own. Through the cooperation of the stopper 64 and the elastic buckle 65, the position of the chromatographic column protection ring 61 in the detection body 1 is firmly fixed to prevent displacement or damage caused by shaking or vibration.

[0038] The chromatographic column body 8 is spirally wound in the detection body 1 , and a heater 11 is fixed at the center of the detection body 1 . The heater 11 is used to heat the chromatographic column body 8 to maintain a stable temperature in the chromatographic column body 8 .

[0039] Temperature is a very important parameter in the chromatographic analysis process. The heater 11 heats the chromatographic column body 8 to maintain its internal temperature within a certain range to ensure the accuracy and stability of the chromatographic analysis. Usually, the heater 11 works according to a preset temperature program and automatically adjusts the heating power to keep the internal temperature of the chromatographic column constant. The heater 11 can ensure that the temperature in the chromatographic column body 8 remains stable, thereby reducing the impact of temperature fluctuations on the chromatographic analysis results.

[0040] A vaporization chamber 12 is provided on one side of the top of the detection body 1. During the detection process, the liquid sample is injected into the vaporization chamber 12 through the pipetting component 3 or other means. The vaporization chamber 12 heats the sample, heats the liquid sample to above its boiling point, and quickly converts the sample into a gaseous state. The vaporized sample is then sent into the chromatographic column body 8 through a pipeline for subsequent separation and detection. A detector 13 is also installed on the top of the detection body 1. A tail blowing device 19 is also provided in the detection body 1. The tail blowing device 19 is connected to the detector 13 through a pipeline. The vaporization chamber 12 is used to heat the liquid sample to be detected into a gaseous sample. The gaseous sample enters the chromatographic column body 8 for separation. One end of the chromatographic column body 8 is interconnected with the bottom of the tail blowing device 19. The detector 13 is installed on the top of the detection body 1. It is a device for detecting the components separated from the chromatographic column body 8. The type of the detector 13 can be determined according to the specific detection requirements, such as a flame ionization detector.

[0041] After the gaseous sample is separated by the chromatographic column body 8, different components will flow out in sequence according to their retention time in the chromatographic column. These outflow components enter the detector 13 through the pipeline. The detector 13 detects according to the properties of the components (such as conductivity, refractive index, mass, etc.), and converts the detected signals into electrical signals for output. These electrical signals are then received and processed by the controller 2 to obtain information such as the concentration and retention time of each component.

[0042] A gas cylinder protection box 5 is provided on one side of the outside of the detection body 1, and a nitrogen cylinder 14, a hydrogen cylinder 15 and a compressed air cylinder 16 are placed in the gas cylinder protection box 5. The nitrogen cylinder 14 provides the required nitrogen for detection, the hydrogen cylinder 15 provides the required hydrogen for detection, and the compressed air cylinder 16 provides the necessary compressed air for detection. The gas outlets of the nitrogen cylinder 14, the hydrogen cylinder 15 and the compressed air cylinder 16 are also connected to a gas filter 17 and a flow valve 18 through a pipeline. The gas filter 17 is used to filter various gases to provide clean gas for detection. It is installed on the gas supply pipeline to filter nitrogen, hydrogen and compressed air, remove impurities and moisture therein, and ensure that clean gas is provided for detection. The flow valve 18 controls the flow rate of the gas and is installed on the gas supply pipeline to control the flow rate of the gas.

[0043] The nitrogen cylinder 14, the hydrogen cylinder 15 and the compressed air cylinder 16 are all provided with a pipeline assembly 7, and the pipeline assembly 7 includes a first pipeline 71, an air inlet pipe 72, a second pipeline 73, and a third pipeline 74. The first pipeline 71 is used to pass the nitrogen in the nitrogen cylinder 14 into the vaporization chamber 12, the air inlet pipe 72 passes the gaseous product and nitrogen into the chromatographic column body 8, the second pipeline 73 passes the hydrogen into the tail blowing device 19, and then the hydrogen, nitrogen and gaseous samples pass through the tail blowing device 19 into the detector 13 for reaction detection, and the third pipeline 74 passes the compressed air into the detector 13 to provide the required air for detection.

[0044] A sample bottle conversion assembly 4 is also provided on the side of the top of the detection body 1 away from the vaporization chamber 12. The sample bottle conversion assembly 4 is used to receive various sample bottles to be detected. A pipetting assembly 3 for transferring the sample in the sample bottle on the sample bottle conversion assembly 4 to the vaporization chamber 12 is also provided at the top of the detection body 1 near the sample bottle conversion assembly 4. The sample bottle conversion assembly 4 includes a turntable 41, a sample bottle sleeve 42, a sample bottle body 43 and a rotating drive 44. The rotating drive 44 is fixed on the detection body 1. The output end of the rotating drive 44 is interconnected with the turntable 41. As the core component of the sample bottle conversion assembly 4, the turntable 41 switches different sample bottles by rotating. The rotating drive 44 is used to drive the turntable 41 to rotate. The turntable 41 is also provided with a sample bottle sleeve 42 for limiting the sample bottle body 43. The sample bottle body 43 is inserted into the sample bottle sleeve 42. The sample bottle sleeve 42 is used to limit and fix the sample bottle body 43. The design of the sample bottle sleeve 42 should ensure that the sample bottle body 43 can be stably inserted therein and prevent it from falling off during rotation or movement.

[0045] The pipetting assembly 3 also includes a lateral moving module 31, a syringe holder 32, a micro-syringe 33 and a lifting and moving module 34. The lifting and moving module 34 is fixed on the top of the detection body 1. The lateral moving module 31 is arranged on the lifting and moving module 34. The lifting and moving module 34 is used to drive the lateral moving module 31 to move up and down. The syringe holder 32 is arranged on the lateral moving module 31. The lateral moving module 31 is used to drive the syringe holder 32 to move back and forth. The syringe holder 32 is used to clamp and fix the micro-syringe 33.

[0046] In this embodiment, the turntable 41 is driven to rotate by the rotating driving member 44, so that the sample bottle body 43 to be tested is rotated to the bottom of the pipetting component 3, and the lifting and moving module 34 drives the lateral moving module 31 and the micro-injection syringe 33 to descend, so that the needle of the micro-injection syringe 33 is inserted into the sample bottle body 43. After the micro-injection syringe 33 absorbs a certain amount of sample, the lifting and moving module 34 and the lateral moving module 31 work together to move the micro-injection syringe 33 to the top of the vaporization chamber 12, and the micro-injection syringe 33 injects the absorbed sample into the vaporization chamber 12 for subsequent chromatographic analysis.

[0047] Working principle: When in use, the chromatographic column body 8 is placed in the chromatographic column limiting groove 66, the two semicircular structures are spliced ​​into the chromatographic column protection ring 61, and fixed by bolts. Then, the slider 62 is matched with the slide rail 63 to push the chromatographic column protection ring 61 into the detection body 1. At this time, the limiting member 64 is inserted into the elastic buckle 65 for fixing to prevent the chromatographic column protection ring 61 from shifting during detection. Then, the staff injects the sample to be tested into the sample bottle body 43, inserts various sample bottle bodies 43 into the sample bottle sleeve 42, and then places the micro-syringe 33 into the syringe holder 32, and fixes the micro-syringe 33 by the syringe holder 32. At this time, the micro-syringe 33 is sucked by the lifting and moving module 34 and the lateral moving module 31. Take the sample in the sample bottle body 43 and transfer the sample to the vaporization chamber 12. At this time, the vaporization chamber 12 heats the liquid sample to a gaseous state. At the same time, the nitrogen in the nitrogen bottle 14 is introduced into the vaporization chamber 12 through the action of the flow valve 18. The nitrogen and the gaseous sample enter the chromatographic column body 8, and the chromatographic column body 8 is spiral, so that the various components in the sample are gradually separated in the chromatographic column body 8. Then the sample enters the tail blowing device 19, the hydrogen in the hydrogen bottle 15 enters the tail blowing device 19, and then the compressed air in the compressed air bottle 16 enters the detector 13, and the sample enters the detector 13 from the tail blowing device 19, and the components in the sample are detected by the corresponding components in the detector 13. Then, the detector 13 converts the detection data into electrical signals and sends them to the controller 2 to draw a chromatogram.
