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:
The present invention relates to a kind of large flow flowing cell, for the preparation of liquid chromatography (ultraviolet/ultraviolet-visible) detecting device.
Background technology:
Liquid phase chromatography is exactly with the chromatography of liquid as mobile phase, is a kind of potpourri compartment analysis means.Main flow detecting device liquid latus rectum is generally 1/8 at present " or less, circulation is inadequate, can not be used for as the preparation of a large amount of samples or the production of product on a small scale, and its structure is as shown in Figure 9.
Summary of the invention:
In order to solve the problems of the technologies described above, the invention provides a kind of large flow flowing cell.
the technical solution adopted for the present invention to solve the technical problems is: a kind of large flow flowing cell, being provided with first-class latus rectum is the liquid in-out valve of 4mm, described liquid in-out valve is embedded with two glands, offer respectively two interior concave stations on the same position on the mutual opposite of described two glands, be provided with two quartz glass plates and two fixture blocks between described two glands, described fixture block is arranged between the interior projection of two glands, make a space that forms flow liquid between two glands after amalgamation simultaneously, described fixture block bottom joins with the edge of quartz glass plate, and two quartz glass plates fixedly are embedded in respectively on the flow liquid viewport of two glands by fixture block, the described liquid in-out valve left and right sides is provided with left end cap, right end cap, described left end cap, the liquid in-out valve, right end cap is fixed into one by trip bolt.
Fixing reliable in order to make between fixture block and gland, further: described fixture block is fixed on gland by straight pin.
Fixing reliable in order to make between left end cap, liquid in-out valve and right end cap, further: the quantity of described trip bolt is at least 3.
Adjustable in order to realize light path, further: described quartz glass plate plate is the design of single face boss.
For the ease of installing, further: the integral body of described liquid in-out valve, left end cap, right end cap all adopts squared design, and described liquid in-out valve bottom is provided with two screw holes are installed.
The present invention is as follows with respect to its advantage of prior art:
1, the fluid latus rectum reaches 4mm, has solved latus rectum little and cause the little situation of flow;
But 2 Fast Installation and disassembly, cleaning are fixed by three screws, and backing out three screws can be with dismounting and change or the cleaning one by one of flow cell inner body;
3, light path is adjustable: change the positive and negative of two quartz glass plates, i.e. the size of capable of regulating light path.As shown below, optional light path is three kinds of 0.5mm, 1.5mm, 2.5mm.

In figure: 1, liquid in-out valve; 2, gland; 2-2, flow liquid viewport; 2-3, interior concave station; 3-1, left end cap; 3-2, right end cap; 4, quartz glass plate; 5, fixture block; 6, trip bolt; 7, straight pin; 8, screw hole is installed.
Embodiment:
The present invention is further described below in conjunction with drawings and Examples.
a kind of large flow flowing cell as shown in Fig. 1～5 is provided with the liquid in-out valve 1 that first-class latus rectum is 4mm, described liquid in-out valve 1 is embedded with two glands 2, offer respectively two interior concave station 2-3 on the same position on the mutual opposite of described two glands 2, be provided with two quartz glass plates 4 and two fixture blocks 5 between described two glands 2, described fixture block 5 is arranged between the interior projection 2-3 of two glands 2, make a space that forms flow liquid between two glands 2 after amalgamation simultaneously, described fixture block 5 is fixed on gland 2 by straight pin 7, the thickness of described fixture block 5 is 1/3～1/2 of this gap, the edge of described fixture block 5 bottoms and quartz glass plate 4 joins, and two quartz glass plates 4 fixedly are embedded in respectively on the flow liquid viewport 2-2 of two glands 2 by fixture block 5, described liquid in-out valve 1 left and right sides is provided with left end cap 3-1, right end cap 3-2, described left end cap 3-1, liquid in-out valve 1, right end cap 3-2 is fixed into one by trip bolt 6, for the ease of fixing, the quantity of this trip bolt 6 is 3, for the ease of installing, described liquid in-out valve 1, left end cap 3-1, right end cap 3-2 integral body all adopts squared design, described liquid in-out valve bottom 1 is provided with two screw hole 8 is installed.And in order to arrive the adjustable of light path, described quartz glass plate 4 can adopt the design of single face boss, so just can by changing the positive and negative of two blocks of quartz glasss, adjust the size of light path.Two quartz glass plates just can done shown in following Fig. 6～8-just, just-anti-, anti--anti-three kinds of combinations, the optional light path of its correspondence is three kinds of 0.5mm, 1.5mm, 2.5mm.
When the liquid import inlet of liquid to be detected by liquid in-out valve 1 enters, because the formed space of interior concave station 2-3 after 2 amalgamations of 5 to two glands of fixture block is large, so, do not overlap fully between two glands, there is certain gap, at this moment, liquid to be detected just can flow into two quartz glass plate 4 gaps by this gap, is then flowed out by liquid outlet; In this simultaneously, detect light and send (deuterium lamp/halogen tungsten lamp etc.) by light source, inject in flow cell perpendicular to the logical light face of quartz glass plate 4, pass that the logical light face of quartz glass plate 4 from the opposite penetrates after fluid, penetrate light and receive also analyzing and processing by the CCD detecting device, thereby reach the effect of material in test fluid.
It is emphasized that: above is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
