Abstract
Description
Technical Field
[0001] This utility model relates to the field of chromatography technology, and in particular to a high-performance chromatograph. Background Technology
[0002] A chromatograph is a device used for chromatographic separation and analysis. It includes an injection system, a detection system, a recording and data processing system, a temperature control system, and a mobile phase control system. Modern chromatographs are characterized by stability, sensitivity, versatility, and high degree of automation. There are gas chromatographs, liquid chromatographs, and gel chromatography instruments. These chromatographs are widely used for the analysis of certain contents of chemical products and polymer materials. Gel chromatography can also determine the molecular weight and distribution of polymer materials.
[0003] A search revealed that patent number "CN221174524U" states that "This utility model relates to the field of gas chromatography technology, specifically a gas chromatography analysis component, including a support frame and a detector. The support frame is fixedly mounted on the upper surface of the detector, and a connecting rod is rotatably connected to the lower surface of the support frame. A tray is fixedly mounted on the lower surface of the connecting rod. This utility model, through the design of the connecting rod, tray, and limiting block, allows the tray to rotate freely on the surface of the support frame. The principle is that the tray and support frame are connected by the connecting rod. The limiting block on the lower surface of the support frame can not only rotate within the limiting groove on the surface of the connecting seat, but the limiting groove can also limit its movement. The user can place the material to be tested into the limiting seat on the tray. Since the tray is rotatable, when the user has finished handling the material, the tray can be stored on the lower surface of the support frame. This design not only improves the efficiency of handling materials but also prevents the tray from taking up extra space." In use, it... By incorporating the connecting rod, tray, and limiting block, this gas chromatography analysis component features a unique placement structure designed for user convenience in handling materials. A tray is designed on the upper surface of the detector, allowing it to rotate freely on the support frame. The tray and support frame are connected by a connecting rod, and the limiting block on the lower surface of the support frame not only rotates within a limiting groove on the connecting seat surface but also has its position limited by the groove. This design ensures the tray will not detach during rotation. Users can place the material to be tested within the limiting seat on the tray. Since the tray is rotatable, it can be stored on the lower surface of the support frame after use. This design improves the efficiency of material handling and avoids the tray taking up extra space. However, placing the material to be tested within the limiting seat on the tray makes cleaning residue difficult after testing, potentially contaminating subsequent sampling and affecting the chromatograph's performance.
