Description

Technical Field

[0001] The utility model relates to the technical field of liquid chromatographs, in particular to a liquid storage bottle fixing and heating mechanism on a liquid chromatograph. Background Art

[0002] Liquid chromatography is an efficient, high-speed, and highly sensitive analytical technique widely used in chemistry, biochemistry, medicine, environmental science, and other fields. It separates and analyzes the different components in a sample by using a high-pressure pump to pass a mobile phase through a chromatographic column containing a stationary phase.

[0003] The operating principle of liquid chromatography is based on the differential interactions between the mobile and stationary phases of a sample. As these components pass through the column, they migrate at different speeds due to the varying strengths of their interactions with the stationary phase, resulting in separation. The mobile phase carries the sample through the column to the detector, which measures the analytes eluting from the column and converts the signals into a chromatogram.

[0004] The liquid chromatograph's reservoir bottle is placed at the top of the instrument, above the infusion pump, to maintain a certain static pressure differential for the infusion. The reservoir bottle is a container for the mobile phase, typically made of borosilicate glass and available in a variety of sizes. In actual operation, to ensure the separation efficiency of the liquid chromatograph, the migration rate of solutes, the efficiency of the chromatographic column, and other factors, the mobile phase temperature must be controlled. However, existing technologies typically utilize a heating system to control temperature after the mobile phase leaves the reservoir bottle, which results in lag and limitations.
