Embodiment 1

[0025] The invention provides a chromatographic bottle such as attached figure 1 And attached figure 2 Shown, comprise bottle mouth 1 and bottle body 5, bottle body 5 is provided with inlet tube 7 and outlet tube 2 and outlet tube 3, is provided with sample tube in bottle cavity 4; The tubes 3 are connected, and the other end communicates with the inlet tube 2 and the inner cavity 4 of the chromatographic bottle.

[0026] The sample tube includes three sections of B tubes, A tubes, B tubes, and A tubes connected in sequence; the B tube is connected to the inlet tube 7, and the B tube is provided with an opening to communicate with the bottle cavity 4; A The tube is connected to an outlet tube 2. The inlet pipe, A pipe, B pipe, connecting pipe and outlet pipe can be integrally stretched and formed by conventional glass tube processing technology, and placed into the inner cavity of the bottle with reference to the existing glass bottle built-in bottle or handicraft method. ...

Embodiment 2

[0034] This embodiment provides an application of the chromatographic bottle.

[0035] as attached image 3 As shown, the sample flowing out of the chemical reaction unit 6 of the continuous flow analyzer (CFA) passes through the defoaming colorimetric cell 8 to remove the foam, and the colorimetric cell 8 is provided with a waste discharge pipe 9, and the sample after the defoaming is passed through the peristaltic pump 14 suction, flow from the cuvette to the chromatographic bottle. The non-foaming colorimetric cell can also be used. At this time, there is no need to set up a waste discharge pipe and a peristaltic pump. The sample flows out of the colorimetric cell together with the air bubbles, and flows from the colorimetric cell to the chromatographic bottle relying on the driving force of CFA itself. The sample flows into tube B, connecting tube and tube A in the chromatographic bottle from the inlet pipe 7 of the chromatographic bottle. The mouth 1 of the chromatograph...

Abstract

The invention discloses a chromatograph sample bottle which comprises a bottle mouth and a bottle body, wherein, the bottle body is provided with an inlet tube and two outlet tubes and the inner cavity of the bottle body is provided with a sample tube; one end of the sample tube is connected with one of the outlet tubes, while the other end thereof is communicated with the inlet tube and the inner cavity of the chromatograph bottle body. The chromatograph sample bottle of the invention has special and novel structure and is convenient for storing flowing samples, especially suitable for storing samples with large flow or higher flow speed, and can be suitable for various chromatograph sample ways such as entering a sample needle and fetching the sample, thus solving the problems of sample storing, sample fetching and waste discharging of the flowing samples with large flow rate, being convenient for the real-time analysis of the samples in different reacting time segments, effectively increasing the accuracy of the analyzing result and establishing a basis for a comprehensive and accurate sample analysis.

Description

technical field [0001] The invention belongs to the technical field of experimental instruments, in particular to a chromatographic sample bottle. 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 sample bottles cannot meet the needs. [0004] For example, in the experiment of further liquid chromatography analysis on the mobile phase sample flowing out of the continuous flow analysis (CFA) reaction unit, it is necessary to solve the technical problems of storage and sampling of the flow sample, and the samp...
