Description

Technical Field

[0001] This utility model relates to the field of HPLC detection equipment technology, and specifically to a device with HPLC signal detection. Background Technology

[0002] HPLC, also known as high-performance liquid chromatography, high-speed liquid chromatography, high-resolution liquid chromatography, and modern column chromatography, is an important branch of chromatography. It uses a liquid as the mobile phase and employs a high-pressure delivery system to pump single solvents or mixtures of different polarities, buffer solutions, and other mobile phases into a chromatographic column packed with a stationary phase. After separation within the column, the components are detected by a detector, thus enabling the analysis of the sample. This method has become an important separation and analysis technique in fields such as chemistry, medicine, industry, agriculture, commodity inspection, and forensic science.

[0003] Existing equipment with HPLC signal detection requires extracting reagents from reagent tanks during use, and then replacing the reagent tubes after use. However, because the reagent tanks are arranged in two rows in the tank, removing the rear tanks can easily cause the front tanks to tip over. This is inconvenient for operators and results in low stability of the reagent tanks, affecting their performance. Therefore, there is an urgent need for equipment with HPLC signal detection to solve these problems. Utility Model Content
