Abstract

The invention discloses an automatic cleaning and glue pouring platform for a capillary array. A push rod is arranged on an electric translation stage; a pressure sensor is arranged on an end surface of the push rod; a microscale sample injector support and a microscale sample injector are arranged on a direction on which the push rod travels; a tail end of the microscale sample injector is clinging to the pressure sensor, and a head of the microscale sample injector is connected with a conduit. A capillary support comprises a capillary head pedestal and a capillary central support, which areseparated, wherein a height of the central support can be adjusted manually. A first path of a transparent tee joint is connected with the head of the microscale sample injector through a conduit; a second path is connected with a head of a capillary; and the third path is connected with a liquid bath liquid bath through a conduit. A pressure sensor display meter is disposed on a platform. The translation stage is equipped with a meter controller with a faceplate, a stepping motor and a direct-current power supply thereon. The platform of the invention can carry out repetitive automatic cleaning and glue pouring on the capillary array, and has advantages of high degree of automation, high cleaning and glue pouring efficiency, compact structure, simple operation and reliable performance, etc.

Description

technical field [0001] The invention relates to biological analysis technology, in particular to a capillary array automatic cleaning and glue pouring platform. Background technique [0002] Capillary electrophoresis is that under the action of an electric field, the sample migrates in the capillary, and different components in the sample have different migration speeds to achieve separation and detection in the capillary, and the sample is analyzed through the detected signal. This technology is widely used in biochemical analysis, such as DNA and protein separation and analysis. It has high separation efficiency, low sample consumption and easy automation. It is widely used in DNA sequencing, biological and clinical research, forensic identification, environmental protection, analytical chemistry and food. It has a wide range of applications in detection and other fields. [0003] At present, the cleaning and filling of capillary arrays adopts direct injection or semi-aut...
