Automatic sample feeding tray for temperature-controllable type microreactor with magnetic stirring function

Abstract

The invention discloses an automatic sample feeding tray for a temperature-controllable type microreactor with a magnetic stirring function, which comprises a tray, wherein a middle water bath solution cavity is arranged in the tray; a plurality of sample bottle slots used for holding sample bottles are formed in an insertion mode on the middle water bath solution cavity; the outer circumferential surfaces of the sample bottle slots are provided with four-phase stepping coils electrically connected with a circuit outside the tray and are provided with shielding layers for shield; and magneticforce stirrers for electro-magnetic induction with the four-phase stepping coils are arranged in the sample bottles inserted into the sample bottle slots. The automatic sample introduction tray has the advantages that a sample which does not react can be put into the tray and measurement time is set, thereby reaching a purpose of automatically detecting the sample; no manual operation is involvedin the sample feeding process, and the advantage of automatic sample feeding is brought into full play. The seamless connection of the test is realized, and transferring sample measurement does not need manual intervention. The stirring modes based on multiple schemes meet the sample detection requirements of different groups, the problem of uneven stirring of the traditional stirrer is solved, and the problem that mutual influence of rotors in a multi-position stirrer is also solved.

Description

technical field [0001] The invention relates to an automatic sampling tray with the function of a microreactor. In particular, it relates to an automatic sampling tray with a high degree of integration and a temperature-controllable micro-reactor with a magnetic stirring function. Background technique [0002] In general analytical chemistry, in order to realize automation and high-throughput analysis, autosamplers are often used to carry sample trays. The sampler carrying tray is often used in an analytical instrument, and has multiple positions (usually tens or more than a hundred) where the container containing the analytical sample to be determined can be placed in the position marked with a fixed number on the tray , set the sampling point and sampling sequence in the workstation program, and the autosampler will automatically run the settings on the software side, realizing automatic sampling and high-throughput quantification, and can achieve 24-hour operation under ...

Problems solved by technology

It must put the collected or prepared sample into the tray to realize automatic sampling, but when there is a sample (such as a chemical reaction in progress or other conditions that require stirring, heating, etc.) that needs to be sampled regularly, online monitoring of sample changes In some cases, the sample can only be manually taken and put into the sample bottle, and then put into the tray for measurement, which requires manual participation in the sampling process, which is no different from manual sampling, and cannot take advantage of automatic sampling

[0004] This type of injector has a low degree of integration on the tray, and only involves the final sample injection process of the entire measurement process. It requires a variety of other equipment to complete the pre-sample processing and other processes, and cooperate with it to complete the entire measurement. In this process , cannot be seamlessly connected, and must be manually intervened to transfer samples for measurement
