Abstract

The invention discloses a chromatographic bottle for continuous flow, segmented sampling and sample storage. The chromatographic bottle comprises a bottle neck, a bottle body, a tube A, a tube B and a tube C, wherein an outlet end close to an inlet end of the tube A and an outlet end away from the inlet end of the tube A are arranged on the tube A and connected with inlet ends of the tube C and the tube B respectively; the inlet end of the tube A is connected with an inlet tube; an outlet end of the tube B is communicated with an inner cavity of the bottle body of the chromatographic bottle; and an outlet end of the tube C is connected with a flow division outlet tube. The chromatographic bottle is applicable to various chromatographic sample injection modes, such as sampling by a sample injection needle, so the problems of interval, sample storage, sampling and waste discharge of test samples which are treated by other equipment and flow out step by step can be solved; furthermore, the chromatographic bottle is convenient for analyzing the test samples in different treatment time periods of a pretreatment device or the test samples of continuous batches treated by the pretreatment device; and therefore, the accuracy of an analysis result can be improved effectively, and a basis is constructed for comprehensive and accurate analysis of the test samples.

Description

technical field [0001] The invention belongs to the technical field of experimental instruments, and in particular relates to a chromatographic bottle for continuous flow 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. [0003] 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. [0004] 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 o...
