Solid adsorbent tube pretreatment automatic sample preparation instrument

Abstract

The invention discloses a solid adsorbent tube pretreatment automatic sample preparation instrument which belongs to the technical field of experimental auxiliary equipment. The solid adsorbent tube pretreatment automatic sample preparation instrument comprises a box, a tube body cutting and dumping device, an automatic sample adding and capping device and a control cabinet. The tube body cuttingand dumping device comprises a tube body jacket, a spring, a rubber gasket, a fixing bolt, a protection cover, a screen, a funnel, a cutting ring and a sensing sample tray. The automatic sample addingand capping device comprises an analytical liquid bottle, a sample introduction pump tube, a peristaltic pump, a manipulator cross beam, a sample introduction tube, an automatic sample adding manipulator, a sample introduction needle, an automatic capping manipulator, a waste drainage tube, a waste liquid tank and a needle washing groove. The solid adsorbent tube pretreatment automatic sample preparation instrument integrates functions of cutting and dumping of a solid adsorbent tube, analytical liquid automatic sample introduction and automatic capping together, relieves manpower, saves time, reduces harm of toxic and harmful substances to person, avoids influence on health of operators performing experiments for long time and reduces occupational hazard. The solid adsorbent tube pretreatment automatic sample preparation instrument provided by the invention aims at avoiding harm to person under the premise of guaranteeing experiment accuracy, and improves experiment efficiency.

Description

technical field [0001] The invention belongs to the technical field of experimental auxiliary equipment, in particular to an automatic sample preparation instrument for solid adsorbent tube pretreatment. Background technique [0002] At present, the solid adsorbent tube is the carrier for collecting organic pollutants in the air. When analyzing and testing samples, sample preparation is required. During the sample preparation process, one end of the solid adsorbent tube needs to be cut and dumped; Resolve the bottle cap. [0003] At present, the on-site sample preparation process in the laboratory mainly has the following problems: [0004] 1. The existing solid adsorbent tubes are made of different materials. For solid adsorbent tubes with thick walls, after cutting with a grinding wheel, it is not easy to break and the speed is slow; [0005] 2. When cutting the solid adsorbent tube, uneven force will lead to irregular cutting or excessive force will break the solid adso...
