Description

Technical Field

[0001] The utility model relates to the technical field of material detection, in particular to a device for a mobile phase bottle. Background Art

[0002] High-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS) are methods used to separate and detect the components of substances and are widely used in food and chemical testing. During these methods, a high-pressure pump is used to deliver the mobile phase stored in a mobile phase bottle into the detection system. The sample to be tested enters the mobile phase via an injector, where it is carried into a chromatographic column and separated into its individual components. The components then flow out of the column in sequence. A detector then measures the concentration of each component and converts the test results into electrical signals, which are transmitted to a recorder for output as a graph.

[0003] During the actual testing process, the normal operation of the detection system has certain requirements for the liquid level of the mobile phase in the mobile phase bottle. If the liquid level is too low, the liquid chromatograph will stop running. To ensure the normal progress of the test, the operator needs to adjust the tilt angle of the mobile phase bottle according to the actual situation during the experiment to maintain a sufficient liquid level. In actual operation, test failures caused by failure to adjust the tilt angle of the mobile phase bottle in a timely or appropriate manner often occur. In the process of adjusting the tilt angle of the mobile phase bottle, the operator may easily cause the mobile phase liquid to spill out of the mobile phase bottle, posing a hidden danger of damaging the experimental instrument. At the same time, when the residual mobile phase is insufficient during the test, the operator needs to replenish the mobile phase in the mobile phase bottle, which inevitably leads to the generation of bubbles in the mobile phase. The shaking of the mobile phase tube may also cause the filter head originally located at the bottom of the mobile phase bottle to move above the mobile phase liquid level, causing the filter head to inhale bubbles and contaminate the mobile phase bottle, which not only affects the accuracy of the experimental results, but may even cause damage to the experimental instrument. In addition, existing liquid chromatographs and liquid-mass spectrometers often place mobile phase bottles on a platform on top of the instrument, and multiple mobile phase bottles are placed in a row, further increasing the difficulty for operators to disassemble, adjust, and add mobile phase to the mobile phase bottles.

[0037] Preferably, the movable support structure 4 includes an upper support 41, an upper hole 42, a lower support 43, a lower hole 44, a pillar 45, a pin hole 46 and a roller 47. The upper hole 42 is opened on the upper support 41, the lower hole 44 is opened on the lower support 43, the pillar 45 is installed between the upper support 41 and the lower support 43, the pin hole 46 is opened on the lower support 43, and the roller 47 is installed at the lower end of the lower support 43.

[0038] This structure can make the bottle 1 more stable, and the roller 47 can facilitate the staff to rotate and move the movable support structure 4, and rotate or move the required bottle 1 to a position convenient for the staff to use, so that the staff can use the bottle 1, which is beneficial to ensuring work efficiency.

[0039] Preferably, the number of the upper hole 42 , the lower hole 44 , the pillar 45 and the roller 47 is four.

[0040] Preferably, the fixed support structure 5 includes a support leg 51, a sliding bearing 52 and a support spring 53. The sliding bearing 52 is installed on the support leg 51. The support 45 passes through the sliding bearing 52 and is installed and connected with the support spring 53. The support spring 53 is located between the support 45 and the lower support 43.

[0041] This structure can fix the movable support structure 4 after the movable support structure 4 rotates or moves to a suitable position, so that it cannot move or rotate, effectively avoiding the phenomenon that the staff cannot use the bottle 1 due to the displacement of the movable support structure 4 when using the bottle 1, which is conducive to ensuring work efficiency.

[0042] Preferably, the number of the supporting legs 51 is two, and the number of the sliding bearings 52 and the springs 53 is four.

[0043] Preferably, the locking structure 6 includes a claw 61, a protruding cantilever 62, a cylindrical pin 63, a claw lock tongue 64 and a circular hole 65; the protruding cantilever 62 is installed at the left end of the claw 61, the cylindrical pin 63 is installed at the lower left end of the protruding cantilever 62, and a spring is provided underneath, the claw lock tongue 64 is installed at the right end of the claw 61, and the circular hole 65 is opened on the lower side of the claw 61, and the pin fixes the claw 61 to the lower bracket 43 through the pin hole 46 and the circular hole 65.

[0044] When the staff needs to move the movable support structure 4, they press down the upper support 41, lift the legs 51 upward, and lower the support 43 downward, while driving the rollers 47 downward until they touch the ground. Then the staff locks the locking structure 6 to limit the movement between the movable support structure 4 and the fixed support structure 5. This structure can effectively prevent the fixed support structure 5 from extending downward during the movement of the movable support structure 4, which is conducive to ensuring work efficiency.

[0045] Preferably, a funnel 7 and a water pump 8 are further included, and the funnel 7 and the water pump 8 are installed on the upper end of the hard tube 21 and can be detachably installed.

[0046] When the mobile phase needs to be replenished, the staff pulls out the bottle stopper on the hard tube 21 and installs the funnel 7 on the hard tube 21. The mobile phase flows from the funnel into the bottle 1. This process can effectively avoid the generation of bubbles. After the mobile phase is replenished, the staff removes the funnel 7 and reinserts the bottle stopper into the hard tube 21. After the work is completed, the staff does not need to open the bottle cap 2. They can pull out the bottle stopper on the hard tube 21 and install the water pump 8 on the hard tube 21. Use the water pump 8 to extract the mobile phase from the bottle 1. After the mobile phase is extracted, the staff removes the water pump 8 and reinserts the bottle stopper into the hard tube 21. This process is conducive to ensuring work efficiency.

[0047] The specific use includes the following process:

[0048] In the first step, after the staff injects a sufficient amount of mobile phase into the bottle 1, the bottle cap 2 is screwed into the bottle mouth of the bottle 1. Then, the bottle 1 is placed in the movable support structure 4, and the movable support structure 4 is pushed to a suitable position. The movable support structure 4 is rotated to a suitable position. This position is convenient for the staff to use the bottle 1. The staff opens the locking structure 6, and the lower support 43 bounces upward, driving the roller 47 to move upward at the same time. At this time, the support leg 51 also moves downward to against the ground, making the movable support structure 4 unable to move.

[0049] In the second step, the staff connects the upper hose 31 on the bottle 1 to the instrument, and then starts the instrument. When the mobile phase in the bottle needs to be replenished, the staff unplugs the bottle cap on the hard tube 21 and installs the funnel 7 on the hard tube 21. The mobile phase flows into the bottle 1 from the funnel 7. After the mobile phase is replenished, the staff removes the funnel 7 on the hard tube 21 and reinserts the bottle cap into the hard tube 21.

[0050] In the third step, after the experiment is completed, the staff unplugs the bottle cap on the hard tube 21, installs the water pump 8 on the hard tube 21, and manually extracts the mobile phase in the bottle 1. After the mobile phase is extracted, the staff removes the water pump 8 on the hard tube 21 and reinserts the bottle cap into the hard tube 21.

[0051] In the fourth step, the staff presses down the upper bracket 41. At this time, the support legs 51 are lifted upward, and the lower bracket 43 is lowered, driving the roller 47 to move downward until it touches the ground. Then, the staff locks the locking structure 6 to limit the movement between the movable bracket structure 4 and the fixed bracket structure 5. Finally, the staff pushes the movable bracket structure 4 to push the bottle 1 back to the appropriate position for next use.
