Chromatographic bottle suitable for continuous segmented sampling and sample storing

Abstract

The invention discloses a chromatographic bottle suitable for continuous segmented sampling and sample storing. The chromatographic bottle comprises a bottleneck and a shell, wherein, the shell is provided with a core space of the shell, an inlet tube, an outlet tube and a split outlet tube, the core space of the shell is provided with a sampling tube, the sampling tube comprises a tube A, a tubeB, a tube C and a tube D, the inlet end of the tube A is connected with the inlet tube, the outlet end of the tube A is connected with the inlet ends of the tube C and D respectively, the outlet end of the tube C is connected with the split outlet tube, the outlet end of the tube D is connected with the inlet end of the tube B, and the outlet end of the tube B is communicated with the core space of the shell. The chromatographic bottle is suitable for various ways of sample introduction such as sampling by injection needle, capable of solving the problem of the sample in the process of flowing out by segments and automatic and continuous processing after processed by other equipment, and is convenient for real-time analyzing samples in different process time slots of pretreatment equipment or processed continuous batches of samples.

Description

technical field [0001] The invention belongs to the technical field of experimental instruments, in particular to a chromatographic bottle suitable for continuous and segmental sampling and storage. Background technique [0002] Existing chromatographic bottles usually include a bottle mouth and a bottle body except the bottle cap. The sample is loaded from the mouth of the bottle, and the sample needle is taken from the mouth of the bottle. Such chromatographic vials can only be used to store a fixed amount of samples, for example, 1ml, 5ml, etc. volumes of samples are loaded at one time, and then taken. If there is a steady stream of samples that are continuously delivered, the existing chromatographic bottles cannot meet the needs. [0003] The applicant provided a chromatographic bottle in the patent No. ZL 200810027209.1 and the patent application No. 200810027210.4, which solved the problem of storage and storage of mobile phase samples flowing out of the continuous ...

AI Technical Summary

Problems solved by technology

[0004] But described chromatographic bottle can not solve the technical problem of interval, storage and sampling of segmental outflow sample at the same time, for example, in the experiment that further liquid chromatographic analysis is carried out to the mobile phase sample that flows out after being processed by automatic solid phase extraction instrument , it is necessary to solve the technical problems of the interval, storage and sampling of the segmented outflow samples. The samples in the chromatographic bottle are not only required to be mobile and instant, but also must be distinguishable at intervals, which can cooperate with sampling from the chromatographic bottle. for further analysis

[0005] And at present, do not see the bibliographical information relevant to described chromatographic bottle
