Description
Technical field
The present invention relates to a kind of constant current thin layer chromatograph, specifically a kind of can to TLC separation, analysis, imaging device.
Background technology
Thin layer chromatography is conventional separating organic matters method, moves on to outside chromatography cylinder by chromatoplate when developing solvent line reaches the top, and under multi-wavelength excites, detects amount and the chemical constitution of the light speckle launched. Chromatoplate move on to outside chromatography cylinder after can not chromatography in the same direction again, when developing solvent line reaches the top, developer flow prompt drop is low, and Tomography Velocity is non-constant, and separating degree reduces, it is impossible to continue to separate the component of long retention time. The lasting longer chromatography time obtains the key problem that high separation is chromatography, in order to reach satisfied separating degree, it is necessary to the state of the layer of monitoring analysis in real time.
Summary of the invention
In order to overcome above-mentioned deficiency, the present invention provide a kind of constant current can be kept to be easily separated thin layer chromatography, analyze, constant current thin layer chromatograph that imaging carries out simultaneously.

The invention has the beneficial effects as follows: the front-back of L-type quartz chromatography cylinder is by uv-transmitting quartz plate manufacture can pass through ultraviolet, launch light speckle after making to be excited by the Organic substance of chromatography. The L-shaped design in cylinder bottom portion for before chromatography by L-type quartz chromatography cylinder to L bottom direction 90-degree rotation, make developing solvent balance between gas-liquid two-phase. Constant current block is manufactured by 2000 order quartz ceramic for filtration, and when solvent front reaches the top edge of expansion plate, developing solvent is subject to the siphon of constant current block and can continue to launch, and duration of run adds more than 3 times, makes separating degree R strengthen because adding duration of run. Inserting in main folder after control wet rod upper leaching 0.5mL concentrated sulphuric acid, the wet rod of control inserts in main folder, for controlling the moisture in gas phase, produces to control the effect of humidity. 2 254nm ultraviolet source lamp symmetries are distributed on the left and right side frame that lamp is sat, in the uniform illuminance of acquisition everywhere of chromatoplate. 2 365nm ultraviolet source lamp symmetries are distributed on the left and right side frame that lamp is sat, in the uniform illuminance of acquisition everywhere of chromatoplate. 4 LED visible light source lamp symmetries are distributed on the corner frame that lamp is sat, in the uniform illuminance of acquisition everywhere of chromatoplate. In the rectangle perforate of photographic head plate forward-mounted, the photographic head of different model can be installed in rectangle perforate, by terminals such as the incoming microcomputer of USB interface or wireless network or mobile phones. Lamp is controlled by time control circuit plate, images when lamp is bright, it is prevented that crosses the probability that long ultraviolet radiation makes separated Organic substance decompose, also extends the life-span of lamp. Under the exciting of 254nm, 365nm and LED visible light, separated Organic substance speckle is imaged respectively by certain time interval, can transmit to the terminal such as microcomputer or mobile phone, carry out chart adding analysis. After duration of run t1, the 1st speckle, close to solvent front, images picture 1;After duration of run t2, front 1 speckle disappears in constant current block, images picture 2; After duration of run t3, front 2 speckles disappear in constant current block, image picture 3; After duration of run tn, front n speckle disappears in constant current block, images picture n. The available chromatography spectrogram EXPANSION EQUATION FOR STEEL formula of the relation of picture 1 to picture n is overlapped, and obtains the spectrogram of whole speckle. The available method changing constant current block obtains Micro-monomer. Chromatoplate after constant current block siphon can Reusability. Simple in construction, easy to use.
