AI Technical Summary

Technical Problem

Existing liquid chromatography analyzers have a large number of consumable materials in isocratic elution schemes, making it difficult to accommodate the elution requirements of different types of variants, resulting in a decrease in the accuracy of HbA1c detection.

Method used

Independent first and second driving components are used to deliver the first and second liquid phase fluids to the storage component for mixing to form a third liquid phase fluid of a single concentration. The third liquid phase fluid is then driven by the second driving component to flow through the chromatography column for elution, thereby realizing the online preparation and storage of liquid phase fluid of the target concentration.

Benefits of technology

It reduces the amount of material in the liquid phase during isocratic elution, allows for concentration adjustment based on different variant types, accommodates the elution requirements of different variant types, and improves the accuracy of HbA1c detection.

Abstract

The application is suitable for the field of in-vitro diagnosis equipment, and discloses a liquid chromatograph. The liquid chromatograph comprises a liquid phase fluid conveying assembly, a chromatographic column, a detector and a controller; the liquid phase fluid conveying assembly comprises a storage component, a first driving component and a second driving component independent of the first driving component, the first driving component is used for driving a first liquid phase fluid from a first container to the storage component and driving a second liquid phase fluid from a second container to the storage component, so that the first liquid phase fluid and the second liquid phase fluid are mixed in the storage component at a preset ratio to form a third liquid phase fluid of a single concentration and are stored in the storage component; and the second driving component is used for driving the third liquid phase fluid to flow through the chromatographic column from the storage component, so that the third liquid phase fluid elutes a test liquid adsorbed on the chromatographic column. The application can realize the function of isocratic elution by using the liquid phase fluid prepared on line from two liquid phase fluids.
