Description

Technical Field

[0001] The utility model relates to the technical field of liquid chromatographs, in particular to a portable liquid chromatograph. Background Technique

[0002] A liquid chromatograph is an analytical instrument widely used in the fields of chemistry, biology, and environment. A liquid chromatograph mainly consists of a liquid reservoir, a pump, an injector, a chromatographic column, a detector, and a recorder. Among them, the liquid reservoir is used to store the mobile phase, the pump is responsible for transporting the mobile phase to the chromatographic column at a stable speed and pressure, the injector is used to introduce the sample to be tested into the chromatographic column, the chromatographic column is the key component for sample separation, and the detector is used to monitor the concentration of each component in the sample and transmit the signal to the recorder for recording and analysis. During the research and development and production process of drugs, a liquid chromatograph can perform qualitative and quantitative analysis on raw materials, intermediates, and finished products of drugs to ensure that the active ingredients, impurity content, and stability of drugs meet the quality standards. In order to facilitate the carrying of the liquid chromatograph, generally, rollers are installed at the bottom to facilitate the movement of the liquid chromatograph;

And when the liquid chromatograph is collided during transportation, due to the lack of a timely alarm mechanism, users often cannot immediately detect the damage of the instrument.

[0004] To solve the above problems, a portable liquid chromatograph is proposed in this application. Content of the Utility Model
