Description

Technical Field

[0001] The utility model relates to the technical field of chromatographic column filtering devices, in particular to a chromatographic column filtering device. Background Art

[0002] Chromatographic column filters are a crucial component of liquid chromatography (LC) systems, primarily used to protect the column from particles and impurities in the sample, thereby improving the accuracy, reproducibility, and lifespan of chromatographic analyses. Their primary function is to remove particulate matter, macromolecules, and other impurities that could affect analysis before the sample enters the column. These devices are typically installed in the tubing between the injection system and the chromatographic column to ensure that the sample entering the column is clean and pure. With the widespread application of liquid chromatography, column filters have become critical equipment for ensuring sample accuracy and chromatographic analysis stability. Market demand for efficient and reliable filters continues to grow to meet the demands of scientists across diverse fields for high-quality and efficient chromatographic analyses.

[0003] However, the existing chromatographic column filtering device has poor filtering performance and needs to be frequently disassembled to clean the internal filter screen, which is time-consuming and labor-intensive and causes inconvenience to the staff. Therefore, a chromatographic column filtering device is proposed. Utility Model Content
