Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, specifically to a chromatographic mobile phase container. Background Technology

[0002] Mobile phase storage bottles are common auxiliary equipment used in laboratories with high-performance liquid chromatographs (HPLC), ion chromatographs (IGC), and gel solid-phase extraction systems (GPE). Currently, while most HPLC systems can set and monitor the minimum mobile phase level to stop the infusion pump, they lack a clear alarm, potentially missing the optimal warning period and causing delays in data acquisition. Furthermore, due to the lack of obvious instrument warnings, human error, insufficient mobile phase, or other issues can lead to pump idling, tubing runs, instrument damage, and inability to acquire data. Additionally, because mobile phases need frequent replacement and preparation information labels need to be updated regularly, sometimes lab technicians are busy with other tasks and fail to find and refill labels in time, resulting in missing or outdated information. This can lead to misuse of the mobile phase or difficulties in tracing and analyzing problems. Even when reagent labels are replaced on time, frequent tearing and pasting leave residue on the bottle, affecting its appearance. Utility Model Content

[0017] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a schematic diagram of the structure of the mobile phase storage bottle body in the chromatographic mobile phase container provided by this utility model; Figure 2 This is a schematic diagram of the structure of the fixing component in the chromatographic mobile phase container provided by this utility model; Figure 3 This is a schematic diagram of the alarm device in the chromatographic mobile phase container provided by this utility model. The chromatographic mobile phase container includes a mobile phase storage bottle body 11 and an alarm device. The upper outer wall of the mobile phase storage bottle body 11 is provided with an information marking area. The information marking area includes multiple information marks 111 arranged side by side and spaced apart along the axis 11 of the mobile phase storage bottle body, and a writing whiteboard 112 respectively provided on one side of each information mark 111. The writing whiteboard 112 is detachably connected to the mobile phase storage bottle body 11. The alarm device includes a fixing member 121 and a non-contact liquid level sensor assembly 122. The fixing member 121 is sleeved on the lower outer wall of the mobile phase storage bottle body 11. The non-contact liquid level sensor assembly 122 is connected to the fixing member 121, and the detection end of the non-contact liquid level sensor assembly 122 is in contact with the mobile phase storage bottle body 11.

[0018] The chromatographic mobile phase container of this invention, by setting a writing whiteboard 112 corresponding to the information label 111 in the information label area, facilitates the user to record relevant information of the mobile phase in the mobile phase storage bottle body 11. Furthermore, by setting a non-contact liquid level sensor assembly 122 on the outside of the mobile phase storage bottle body 11, it can monitor the liquid level of the mobile phase in the mobile phase storage bottle body 11 in real time, and promptly alarm when the liquid level of the mobile phase is lower than a preset value, so that the user can promptly replenish the mobile phase. It is efficient, intuitive, and ensures the continuous operation of data acquisition.

[0019] Specifically, the information identification area includes information labels 111 such as reagent name, reagent concentration, preparer, preparation date, and expiration date. Writing whiteboards 112 are affixed to the outer wall of the mobile phase storage bottle body 11 after the information labels 111. The writing whiteboards 112 are used to record the corresponding information labels 111. They can be made of customized 7cm*1.5cm PET boards, which are lightweight, low-cost, reduce writing residue, and are easy to clean. The writing whiteboards 112 are fixed to the outer wall of the mobile phase storage bottle body 11 by adhesive, ensuring the strength of the fixation between the writing whiteboards 112 and the mobile phase storage bottle body 11, and facilitating the replacement of the writing whiteboards 112.

[0020] Furthermore, the mobile phase storage bottle body 11 is made of high borosilicate glass or transparent polyvinyl chloride, which gives the mobile phase storage bottle body 11 good corrosion resistance and transparency, making it easy for users to observe the state of the mobile phase inside the mobile phase storage bottle body 11.

[0021] Furthermore, the outer wall of the mobile phase storage bottle body 11 is also provided with a scale line 113. The scale line 113 is arranged along the axis of the mobile phase storage bottle body 11 and is located on one side of the information marking area, so as to facilitate the user to observe the amount of mobile phase in the mobile phase storage bottle body 11.

[0022] Furthermore, the outer wall of the mobile phase reservoir body 11 is provided with a conspicuous identification ring 114, which is located radially along the mobile phase reservoir body 11 at the lowest mark of the scale line 113. The contrast between the conspicuous identification ring 114 and the color of the mobile phase reservoir body 11 enhances its visual recognition effect, facilitating the user's observation of whether the mobile phase inside the mobile phase reservoir body 11 is below the lowest mark of the scale line 113, allowing for timely replenishment. Specifically, the conspicuous identification ring 114 can be a bright color such as bright yellow, red, or fluorescent green to create a sharp contrast with the color of the mobile phase reservoir body 11, ensuring its effective indication.

[0023] Furthermore, the writing whiteboard 112 is positioned between the information label 111 and the scale line 113. This arrangement allows the information label area and the scale line 113 to be arranged more compactly on the outer wall of the mobile phase storage bottle body 11, enabling a more intuitive overall display of the relevant information and quantity of the mobile phase inside the mobile phase storage bottle body 11.

[0024] Furthermore, the non-contact liquid level sensor assembly 122 includes a non-contact liquid level sensor 1221, an alarm 1222, a power interface 1223, and a power supply 1224 connected in sequence. The non-contact liquid level sensor 1221 is detachably connected to the fixing member 121. The power supply 1224 is electrically connected to the alarm 1222 and the non-contact liquid level sensor 1221 through the power interface 1223, providing working power to the alarm 1222 and the non-contact liquid level sensor 1221 to ensure their normal operation. The non-contact liquid level sensor 1221 is used to monitor the liquid level of the mobile phase in the mobile phase storage bottle body 11. When the liquid level of the mobile phase in the mobile phase storage bottle body 11 is lower than a preset value, the alarm 1222 will sound an alarm, facilitating timely replenishment of the mobile phase by the user. This efficient and intuitive method ensures timely and stable output of detection data.

[0025] Specifically, the power interface 1223 is a USB power interface, and the power supply 1224 is a boxed battery power supply. Connecting to the boxed battery power supply via the USB power interface is simple and convenient, facilitates quick replacement of the power supply 1224, and ensures continuous operation of the non-contact liquid level sensor assembly 122.

[0026] Furthermore, the fixing component 121 is an American-style hose clamp with a handle, which is safe, reliable, easy to use, and has extremely strong fastening force, and can effectively fix the non-contact liquid level sensor assembly 122 to the outer wall of the mobile phase storage bottle body 11.

[0027] Furthermore, a buffer layer 1211 is provided on the inner side of the American-style handle clamp. The non-contact liquid level sensor 1221 is embedded in the buffer layer 1211 and fixed to the inner side of the American-style handle clamp with hot melt adhesive, achieving a detachable connection with the American-style handle clamp. The buffer layer 1211 allows for a tighter fit between the American-style handle clamp and the outer wall of the mobile phase storage bottle body 11, ensuring that the detection end of the non-contact liquid level sensor 1221 contacts the outer wall of the mobile phase storage bottle body 11, and preventing the American-style handle clamp from causing excessive compression to the mobile phase storage bottle body 11.

[0028] In use, the chromatographic mobile phase container of this invention allows the user to first select a mobile phase storage bottle body 11 of different specifications according to the required amount of mobile phase. The prepared mobile phase is then placed into the mobile phase storage bottle body 11 for storage. The user fills in the corresponding whiteboard 112 according to the information labels 111, including reagent name, reagent concentration, preparer, preparation date, and expiration date of the mobile phase, and affixes it to the back of the corresponding information labels 111 on the outer wall of the mobile phase storage bottle body 11. This facilitates the user's viewing of the relevant information of the mobile phase inside the mobile phase storage bottle body 11. Next, a suitable diameter American-style hose clamp is selected according to the specifications of the mobile phase storage bottle body 11, and the non-contact level sensor 1221 is fixed to the inside of the American-style hose clamp with hot melt adhesive. The non-contact level sensor 1221, the alarm 1222, and the power interface 1223 are then connected sequentially via wires. Finally, the American-style hose clamp is fitted onto the mobile phase storage bottle. The non-contact liquid level sensor 1221 is aligned with the conspicuous identification ring 114 on the outside of the main body 11. The non-contact liquid level sensor 1221 is fixed to the outer wall of the mobile phase storage bottle body 11 by tightening the American-style hose clamp on the handle. The power supply 1224 is then connected to the power interface 1223, providing power to the alarm 1222 and the non-contact liquid level sensor 1221. With this configuration, during instrument testing, the amount of mobile phase in the mobile phase storage bottle body 11 can be visually observed by personnel using the scale lines 113 on the outer wall of the mobile phase storage bottle body 11 and the conspicuous identification ring 114. Alternatively, the non-contact liquid level sensor 1221 can monitor the liquid level of the mobile phase in the mobile phase storage bottle body 11 in real time, triggering an alarm when the liquid level falls below a preset value. This allows for timely replenishment of the mobile phase, ensuring efficient and intuitive data acquisition and continuous operation.
