Automatic separate collection device for micro samples

Abstract

The invention discloses an automatic separate collection device for micro samples. The device comprises a worktable, wherein the worktable is provided with a suspended mechanical arm; a horizontal suspension is arranged at the top end of the suspended mechanical arm; the horizontal suspension is located above a suspension liquid sucking and drying part; a dot matrix bottle rack is arranged at thebottom of the worktable; a plurality of chromatographic sample injection bottles can be placed in the inner cavity of the dot matrix bottle rack; a liquid shunt is arranged above the horizontal suspension; and a conveying pipe, a waste liquid pipe and a connecting pipe are respectively arranged on the liquid shunt. According to the device, high automation can be realized; during the operation, collection is carried out according to a pre-designed program; dozens of different sample components can be collected at one time; the small and micro sample components can be accurately collected; the volumes of collected liquid are far smaller than a common liquid drop; the collected samples are stored in the enclosed chromatographic sample injection bottles; and the enclosed environment not only can protect the samples, but also can decrease the cross contamination of the samples.

Description

technical field [0001] The invention relates to the technical field of micro-sample collection, in particular to an automatic classification and collection device for micro-sample. Background technique [0002] The liquid chromatography technology experimental analysis equipment developed based on the different distribution degree of substances in the liquid and solid interface is widely used and various, such as liquid chromatography, high pressure liquid chromatography, fast protein liquid chromatography, etc. In addition, capillary electrophoresis The separation effect is enhanced by an external electric field, and flow cytometry uses a similar principle to separate different biological cell components. When using these devices, it is often necessary to separate the components dissolved in the liquid phase or suspended in the liquid phase Particles collected for further analytical verification or utilization; [0003] The current common practice is to manually collect th...

Problems solved by technology

Fraction collectors provide a certain degree of automation, but chemical distillation experiments have very low requirements for separation accuracy and require a relatively large amount of collected samples, so it is difficult for fraction collectors to meet the growing need for automation in chemical and biological experiments. Requirements and requirements for precise recovery of separated components
