Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as Figure 1~5 The shown large flow flow cell is provided with a liquid inlet and outlet valve 1 with a flow diameter of 4mm, and the inlet and outlet valve 1 is embedded with two glands 2, at the same position opposite to each other of the two glands 2 There are two inner recessed platforms 2-3 respectively, and two quartz glass plates 4 and two clamping blocks 5 are arranged between the two glands 2, and the clamping blocks 5 are arranged inside the two glands 2. Between the bumps 2-3, a space for flowing liquid is formed between the two glands 2 after they are assembled at the same time, and the clamping block 5 is fixed on the gland 2 by a cylindrical pin 7, and the thickness of the clamping block 5 is 1 / 3 to 1 / 2 of the gap, the bottom of the clamping block 5 is in contact with the edge of the quartz glass plate 4, and the two quartz gl...

Abstract

The invention relates to a flowing cell with high flow. The flowing cell is provided with a liquid inlet and outlet valve with the flow diameter of 4mm, the liquid inlet and outlet valve is embedded with two glands, the opposite sides of the two glands are respectively provided with an inner concave table at the same position, two quartz glass plates and two fixture blocks are arranged between the two glands, the fixture blocks are arranged between two bumps of the two glands and are spliced to form a gap for flow between the two glands, the bottoms of the fixture blocks are connected with the edges of the quartz glass plates, the two quartz glass plates are respectively fixedly embedded on flow observation holes on the two glands by virtue of the fixture blocks, a left end cap and a right end cap are respectively arranged at the left side and the right side of the liquid inlet and outlet valve, and the left end cap, the liquid inlet and outlet valve and the right end cap are fixed into a whole by virtue of fastening screws. Compared with the prior art, the flowing cell provided by the invention has the following advantages: 1, the drift diameter of fluid reaches 4mm, thus the problem of small flow caused by small drift diameter can be solved; 2, the flowing cell can be rapidly mounted, dismounted and cleaned; and 3, the optical path is adjustable.

Description

Technical field: [0001] The invention relates to a flow cell with a large flow rate, which is used for preparing a liquid chromatography (ultraviolet / ultraviolet-visible) detector. Background technique: [0002] Liquid chromatography is a chromatography that uses liquid as the mobile phase, and is a means of separation and analysis of mixtures. At present, the liquid diameter of mainstream detectors is generally 1 / 8" or smaller, and the flow rate is not enough, so it cannot be used as a preparation of a large number of samples or production of small-scale products. Its structure is as follows: Figure 9 shown. Invention content: [0003] In order to solve the above technical problems, the present invention provides a large flow flow cell. [0004] The technical solution adopted by the present invention to solve the technical problem is: a large flow flow cell, which is provided with a liquid inlet and outlet valve with a flow diameter of 4mm, and two glands are embedded i...
