Description

Technical Field

[0001] This utility model relates to the field of textile product testing technology, specifically to a solid phase extraction eluent collection device suitable for the detection of azo dyes. Background Technology

[0002] Solid-phase extraction (SPE) is an increasingly widely used sample pretreatment technique in laboratories. SPE utilizes a solid adsorbent to adsorb target compounds from a liquid sample, separating them from the sample matrix and interfering compounds. The target compounds are then eluted with an eluent or desorbed by heating, achieving the separation and enrichment of the target compounds. GB17592-2011, "Determination of Prohibited Azo Dyes in Textiles," uses an extraction column filled with porous granular diatomaceous earth for SPE. After the reaction solution is poured into the extraction column and left for 15 minutes, aromatic amines are eluted with 4 x 20 mL of diethyl ether. Finally, the eluent is collected in a collection bottle for analysis.

[0003] Existing solid-phase extraction (SPE) eluent collection devices for azo dye detection rely on manual control of valves on the SPE tube to release the eluent from the extraction column into a collection bottle. However, this method requires manual observation of the graduations on the collection bottle for quantitative collection, which is prone to errors, resulting in low accuracy and affecting the device's collection performance. Consequently, the device's functionality and overall effectiveness are compromised. Therefore, a suitable SPE eluent collection device for azo dye detection is urgently needed to address these issues. Utility Model Content

[0012] (III) Beneficial Effects Compared with the prior art, this utility model has the following advantages: This invention employs a weighing detection mechanism consisting of a weighing chamber, a weighing sensor, a weighing plate, and an alarm. During the collection of eluent, the collected volume of eluent can be converted into weight, which can be set via the control panel and the threshold of the weighing sensor.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] like Figures 1-3 As shown, a solid-phase extraction eluent collection device for azo dye detection in this embodiment includes a base 1. A weighing chamber 8 is provided in the middle of the upper end of the base 1 to provide an installation position for a weighing sensor 12. The weighing sensor 12 is fixed in the middle of the weighing chamber 8, and quantitative collection of the eluent can be achieved by weighing. A weighing plate 9 is fixed on the detection surface of the weighing sensor 12 to provide a placement position for the collection bottle 7. An alarm 10 is provided on one side of the weighing chamber 8 to alert the staff. An operation panel 11 is installed on one side of the alarm 10 to adjust the threshold of the weighing sensor 12. A bracket 2 is fixed on the upper end of the base 1. An extraction column 3 is installed in the middle of the bracket 2 to elute and extract the reaction solution. A dropper 5 is provided at the bottom of the extraction column 3. A manual valve 6 is installed on the dropper 5 to control the opening and closing of the dropper 5.

[0017] like Figures 1-3 In this embodiment, the weighing chamber 8 is formed on the base 1, the weighing sensor 12 is fixed in the weighing chamber 8 by screws, the weighing plate 9 is fixed on the detection surface of the weighing sensor 12 by screws, the alarm 10 is electrically connected to the weighing sensor 12, and the alarm 10 has an audible and visual alarm function. The operation panel 11 is electrically connected to the weighing sensor 12 and the alarm 10. The operation panel 11 has a reserved display screen. During the collection of eluent, the collection volume of eluent can be converted into weight and set accordingly through the threshold of the operation panel 11 and the weighing sensor 12. Then, the weighing sensor 12 weighs the collection bottle 7 through the weighing plate 9. When the threshold is detected, the alarm 10 is activated to prompt the staff to quickly close the manual valve 6. This method replaces the original visual observation of the collection volume, which can effectively improve the collection accuracy. It not only has a good collection effect, but also has strong functionality.

[0018] like Figures 1-3In this embodiment, the support 2 is fixed to the base 1 with screws, the extraction column 3 is located in the middle of the support 2, the dropper 5 is formed at the bottom of the extraction column 3, both the dropper 5 and the extraction column 3 are transparent, the manual valve 6 is fixed to the dropper 5, the top of the extraction column 3 is fitted with a sealing plug 4, and a collection bottle 7 is placed on the top of the weighing plate 9. The collection bottle 7 is located directly below the dropper 5. During use, the reaction solution is injected into the extraction column 3 for 15 minutes, and then the aromatic amine is eluted with 4*20mL of diethyl ether. After elution, the dropper 5 is opened through the manual valve 6. At this time, the eluent flows into the collection bottle 7 through the dropper 5 by its own gravity for collection and subsequent detection.

[0019] The specific implementation process of this embodiment is as follows: First, place the device in place and connect the external power supply. During use, inject the reaction solution into the extraction column 3 for 15 minutes, and then elute the aromatic amine with 4*20mL of diethyl ether. After elution, place the collection bottle 7 on the weighing plate 9, and set the corresponding threshold of the weighing sensor 12 through the operation panel 11 according to the amount of eluent to be collected. After setting, open the dropper 5 through the manual valve 6. At this time, the eluent flows into the collection bottle 7 through the dropper 5 by its own gravity for collection. During the collection process, the weighing sensor 12 weighs the collection bottle 7 through the weighing plate 9. When the threshold is detected, it will trigger the alarm 10 to work and prompt the staff to quickly close the manual valve 6. This method replaces the original visual observation of the collection amount, which can effectively improve the collection accuracy. It not only has a good collection effect, but also has strong functionality. After collection, the collection bottle 7 is transferred and subsequent testing is performed.
