The utility model is characterized in that the camera is formed by the ultraviolet light source arranged in a shading box body and a commodity camera, the dual-wavelength ultraviolet light source for a short-wavelength band and a long-wavelength band are arranged on the inner side of the top plate of the box body, and a through hole whose inner diameter matches with the outer diameter of a camera lens is arranged in the middle of the top plate of the box body. The side wall of the box body is provided with a movable door, and the base plate of the box body is provided with a specimen stage. The utility model has the advantages that the positioning of the video camera lens and the specimen stage is accurate, and the video camera lens and the specimen stage can be adjusted, following the device; besides, the utility model has easy operation and accurate image pick-up function, and the operation is not necessarily processed in a dark room.
Description
Technical field
The utility model belongs to the equipment special that thin-layer chromatography uses, and is specifically related to be suitable for the observation of thin layer chromatogram and/or a kind of closed dual wavelength ultraviolet thin layer chromatogram camera head that shooting is used.The utility model is equally applicable to the observation analysis of running gel and other need be with the occasion of ultraviolet visualization shooting.
Background technology
The application of chromatographic technique and development are played great impetus for the isolation identification work of compound.Thin-layer chromatography (full name thin-layer chromatographic analysis, Thin-layer chromatography) is a kind of easy, quick, micro-chromatographic process; Have a wide range of applications at the separation and Extraction of natural products, the aspects such as formulation of drug standard.During thin-layer chromatography, silica gel is applied on the flat board (as glass sheet), and (different situations thickness difference is 2mm when separating as preparation to form the skim layer of silica gel; During quantitative measurement 0.5mm; Analyzing when separating is 0.25mm) dry back point sample, launch in organic solvent; The result of thin-layer chromatography obtains some collection of illustrative plates, according to the R of compound standard items
fValue judges whether there is this compound in the equipotential line sample, and the depth of spot colors and size can be estimated this compound number, thereby institute's test sample product are carried out quality control and qualitative analysis.
Some compound itself is colourless, but uv absorption is arranged, so should observe under ultraviolet light and take pictures; The colourless fluorescence that also do not show under uviol lamp of some compound itself when not having suitable developer again, then can add fluorescent material and make fluorescence thin layer and carry out chromatography in adsorbent.The exhibition layer is placed on irradiation under the ultraviolet light, and thin layer plate itself shows fluorescence, and the sample point place does not show fluorescence, can detect the chromatography position of sample.Fluorescent material commonly used mostly is inorganics.The first is showed fluorescence under 254nm ultraviolet light (short-wave band ultraviolet light) excites; Another kind of under 365nm ultraviolet light (long-wave band ultraviolet light) excites, to send fluorescence.
In the prior art, most laboratory is observed with the desk lamp type uviol lamp and is made a video recording.Under this condition,, carry out R according to captured collection of illustrative plates because shooting angle can't be fixed
fWhen value is calculated, will produce bigger deviation.And need under the condition in darkroom or similar darkroom, carry out when taking.
The utility model content
Goal of the invention of the present utility model is to solve deficiency and the defective that exists when thin layer chromatogram is made a video recording in the prior art, develops a kind of easy and simple to handle, closed accurately dual wavelength ultraviolet thin layer chromatogram camera head of shooting.
The technical solution of the utility model is: develop a kind of closed dual wavelength ultraviolet thin layer chromatogram camera head, comprise purple

Above-mentioned dual wavelength ultraviolet source is provided with power control switch respectively at cabinet exterior;
The through hole of internal diameter and camera lens external diameter coupling is set in the middle of the roof box;
Wall box is provided with dodge gate; Box bottom is provided with sample stage.
The above-mentioned parallel apportion of dual wavelength ultraviolet source is arranged on the inboard through hole of top board both sides;
Above-mentioned dual wavelength ultraviolet source is parallel to be set up in parallel in top board one side;
On the above-mentioned top board through hole, the packing ring of scalable lens focus is set;
Above-mentioned casing double side wall is provided with dodge gate;
On the above-mentioned box bottom, the sample stage of band adjustable-height parts is set;
Above-mentioned casing and base plate are movable formula structure.
The utility model has the advantages that:
1. pick-up lens and sample stage accurate positioning and can regulate at random, easy and simple to handle, shooting are accurately;
2. need not under the condition in darkroom or similar darkroom, to carry out.
