Prevent high performance liquid chromatography appearance of jam

The utility model discloses a prevent high performance liquid chromatography appearance of jam, including reservoir, high -pressure transfusion pump, injector, chromatographic column and the detectionand analysis record appearance that connects gradually, it also can be nonrust steel pipe that the pipeline of the connection of high -pressure transfusion pump, injector, chromatographic column anddetection and analysis record appearance can be the hose, be provided with a drain post between reservoir and the high -pressure transfusion pump, the one end and the high -pressure transfusion pump of drain post are connected, and in the drain post other end stretched into the reservoir, the drain post stretched into one end in the reservoir and can dismantle and be connected with a filter equipment, be close to the chromatographic column between injector and the chromatographic column and install the 2nd filter equipment. Prevent pipeline and chromatographic column that can very big degree be blockked up, improve ins
