Unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.
[0025] Example 1
[0026] In a typical embodiment of this utility model, such as Figure 1 As shown, a chromatographic sample loading device for the production of muscone is provided, including a sample container 1, a filter 2, and a support 12. The bottom of the sample container 1 is connected to the filter 2, and the support 12 is disposed on the side wall of the sample container 1. The support 12 is used to increase the overall structural stability of the sample loading device. The chromatographic sample loading device is directly connected to the chromatographic column and is used to add samples to the chromatographic column.
[0027] The sample container 1 has a cylindrical structure and is located on top of the filter 2. It is used for adding samples. A rinsing port 4 is located at the top of the sample container 1, and a rinsing port cover 3 is provided on the rinsing port 4. The rinsing port 4 is used to add rinsing liquid into the sample container 1. A distributor 5 with an umbrella-shaped structure is located at the bottom of the rinsing port 4. The umbrella head of the distributor 5 is connected to the bottom of the rinsing port 4, and it is used for uniform distribution of liquid, thereby achieving thorough rinsing of the sample remaining on the side wall of the sample container 1. An inlet 6 is located at the top of the side wall of the sample container 1, and an inlet cover 7 is provided on the inlet 6. The inlet 6 is connected to a delivery pump. The inlet 6 uses an input pump to add the sample from the sample container into the sample container 1. One end of the input pump is connected to the inlet 6, and the other end is connected to the sample container.
[0028] The filter 2 has a conical structure, and a filter screen 8 is provided at the top of the filter 2. The filter screen 8 is used to filter solid impurities in the sample or rinsing liquid. A liquid level sensor 9 is provided on the side wall of the filter 2. The liquid level sensor 9 is used to measure the liquid level in the filter 2. A sample outlet tube 10 is provided at the bottom of the filter 2. The sample outlet tube 10 is connected to the chromatography column via a delivery pump. A solenoid valve 11 is provided on the sample outlet tube 10. The liquid level sensor 9 and the solenoid valve 11 are respectively connected to the controller 13, thereby realizing the timely closure of the sample outlet tube 10 to prevent air from entering the chromatography column. The controller 13 can be a commercially available product.
[0029] In some other embodiments, the sample container 1 or filter 2 is made of glass or stainless steel. The side wall of the sample container 1 or filter 2 is provided with graduation lines to facilitate observation of the liquid level in the sample loading device.
[0030] The sample loading process of the chromatographic sample loading device for muscone production in this utility model is as follows:
[0031] (1) Close the shower cover 3 on the shower inlet 4, and add the sample into the sample loader 1 through the sample inlet 6 by the delivery pump, and close the sample inlet cover 7. The sample passes through the filter screen 7 in the filter 2 to remove the solid impurities in the sample, and when the liquid level sensor 8 in the filter 2 detects that the liquid surface is higher than the specified height, the controller 13 is linked to open the electromagnetic valve 11, and the sample enters the chromatographic column through the sample outlet pipe 10.
[0032] (2) When the liquid level sensor 8 in the filter 2 detects that the liquid surface is lowered to the specified height, the controller 13 is linked to close the electromagnetic valve 11, and the liquid remains in the cavity of the filter 2 to avoid the air entering the sample outlet pipe 10.
[0033] (3) Open the shower cover 3 on the shower inlet 4 again, add the residual sample in the sample barrel into the shower liquid, and add the sample into the sample loader 1 through the shower inlet 4, and the shower liquid is uniformly distributed through the distributor 5 to sufficiently wash the residual sample on the side wall of the sample loader 1. At the same time, according to the detection of the liquid level sensor 8 in the filter 2, the controller 13 is linked to control the electromagnetic valve 11 to control the sample into the chromatographic column.
