Abstract
Description
Technical Field
[0001] The utility model relates to sample pre-processing, in particular to a mixing device for gas chromatography analysis samples. Background Art
[0002] Gas chromatography analysis began in the early 20th century and has developed rapidly with the emergence of efficient stationary phase materials and sensitive detectors. Due to its high sensitivity, fast analysis speed, and high separation efficiency, it is widely used in many fields, such as environmental monitoring, food and agriculture, petrochemicals, medicine and health, etc. As a key step in gas chromatography analysis, the purpose of sample pretreatment is to convert the sample into a form suitable for gas chromatograph analysis.
[0003] Solvent analysis-gas chromatography is commonly used for sample pretreatment in the environmental monitoring process. This method requires pouring the activated carbon after sampling into the analysis bottle and adding the analysis solution, shaking and analyzing for 30 minutes to mix the sample evenly. Manual shaking is cumbersome, labor-intensive, and inefficient, especially when it cannot handle a large number of samples. The manual shaker still relies on manual labor, which is time-consuming and labor-intensive. Although the vortex mixer is small and convenient, it can only make one sample at a time and cannot be operated in batches. The long-axis disc rotating mixer can shake multiple samples at the same time and is driven by a motor, saving manpower, but it has the following limitations: the number of samples processed at a time is usually less than ten; there is an unstable clamping phenomenon for glass chromatographic bottles or other non-standard containers, which is easy to slip or break; sample containers of different specifications need to design and prepare corresponding fixtures, which increases the complexity and cost of use, and frequent replacement of fixtures will reduce work efficiency; loading and unloading are frequent and laborious.
[0004] In view of the above-mentioned deficiencies in the prior art, the utility model proposes a mixing device for gas chromatography analysis samples which has a wide range of adaptability, a simple structure, is easy to operate, has a low cost of use and can efficiently process a large number of samples in batches. Utility Model Content
[0005] The utility model aims to provide a gas chromatography analysis sample mixing device which has wide adaptability, simple structure, convenient operation, low use cost and can efficiently process a large number of samples in batches.
[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a mixing device for gas chromatography analysis samples, including a base, characterized in that it also includes a bracket, a sample box, a bottle rack, a driving mechanism and a controller, two brackets are respectively fixed on the base and arranged opposite to each other, and a bearing is provided on the bracket. The sample box includes a box body, a flip cover and a central axis. The flip cover is hinged on the box body, and the central axis is fixed on the box body. The sample box is hinged on the bracket through the cooperation of the central axis and the bearing. The size of the bottle rack corresponds to the inner space of the box body. The driving mechanism is fixed on the base, and the driving mechanism is connected to the central axis through a coupling. The signal output end of the controller is connected to the signal input end of the driving mechanism.
[0007] Furthermore, a display screen is also included.
[0008] Furthermore, a limiting member is provided between the inner wall of the box body and the bottle rack.
[0009] Furthermore, the driving mechanism is an electric motor.
[0010] Furthermore, the limiting member is a sponge frame.
[0011] The working process of the utility model is as follows: insert the bottle containing the gas chromatography analysis sample into the bottle rack, put the bottle rack into the box body of the sample box, position it with a limiter, close the flip cover and the box body, operate the driving mechanism through the controller to drive the sample box to rotate forward, reverse and stop according to the regulations, open the sample box, and take out the bottle rack.
[0012] The utility model puts the gas chromatography analysis sample into the sample box along with the bottle rack as a whole, and utilizes the driving mechanism to drive the sample box to turn upside down, thereby ensuring that the sample is mixed evenly.
[0013] The utility model can mix 50 samples at the same time and is suitable for large-scale operations.
[0014] The utility model effectively reduces the use cost by replacing the sponge frame inside to adapt to different bottle racks.
[0015] The utility model has wide adaptability, simple structure and convenient operation. BRIEF DESCRIPTION OF THE DRAWINGS
