Abstract
The utility model discloses a multiple-function thin-layer point-mode ultraviolet analyzer, which is a thin-layer chromatogram analysis point-mode device. A point-mode machine frame which is composed of components (21), (22), (23) and (29) is additionally loaded on the existing instrument panel; the machine frame can motion from top to bottom along a straight pole (23), and can arbitrarily move along a transverse guide rail (30) and a lengthways guide rail (16). A miniature bulb (12) and a magnifier (17) are loaded on the machine frame, which thoroughly overcomes the point-mode unqualified phenomenon caused by natural hand dithering, insufficient sight and inexperience. In addition, the multiple-function thin-layer point-mode ultraviolet analyzer is also provided with a constant temperature heating plate, a circular point-mode tray (15), a camera accessory placing device, a light shield, etc.; the point-mode process is made to be quite convenient, and the precision and the work efficiency of the thin-layer analysis are enhanced.
Description
The utility model relates to a kind of thin-layer chromatographic analysis spot sample device.
The thin-layer chromatography technology has easy, quick, various, good separating effect, detects characteristics such as sensitivity height, has purposes widely in analysis field.Thin-layer chromatography point sample mode directly influences the precision of stratographic analysis, especially to the high performance thin layer chromatography technology that grew up in recent years and use the thin-layer chromatogram scanner determination techniques, the thin layer point sample is an important operation steps, and is very close with the quantitative error and the reappearance relation of stratographic analysis.
At present, in the thin-layer chromatography technical work of China, be to adopt micro syringe and the manual point sample of glass capillary basically.Because the shake naturally of staff damages thin layer easily, produces " pit " on thin layer, influences separating effect.Especially when point sample amount during, just very high for the requirement of operator's " eyesight " and " hand-power " less than 1 microlitre, and the difficulty especially of cooperation between the two; In addition for the point sample of " positive and negative radial chromatography ", the point sample of difficult evaporating solution, and the detection of thin layer plate present such or such difficulty in face of chromatogram being continued to employ the stratographic analysis workers that are everlasting such as taking pictures of data.A kind of " ultraviolet analysis instrument for three purposed " that Shanghai Gu Shu electric light instrument plant, Nantong diformazan physical apparatus factory produce, and " EVA-chromatogram-TLC sample applicator " function of external report is all more single, can not satisfy the needs that the stratographic analysis worker overcomes above-mentioned difficulties.
The purpose of this utility model is to overcome deficiency of the prior art, for the stratographic analysis personnel provide a kind of easy, and practical instrument.
Introduce technical pattern of the present utility model below.
The utility model is to be made of parts such as casing (8), panel (11), frame, guide rails.(22) be a clamper, homemade 0.5 microlitre of its clamping easily～100 microliter amount syringes or kapillary sample applicator has a movable bayonet socket (32) in its lower end riveting, glides in the time of can preventing to push away under the syringe, when using the kapillary sample applicator, this activity bayonet socket can be dialled on one side.Clamper (22) is fixed on the tressel (21), a rubber wheel (31) is housed in the tressel, with revolve axle (27) and turn-knob (28) and directly link to each other, by the rotation turn-knob, tressel can move along straight-bar (23) easy on and off, because staff does not directly contact sample applicator, causes the nonconforming problem of point sample thereby overcome hand tremor.At the clamper front end a mobilizable magnifier (17) is housed, and an optically focused miniature bulb (12) is housed on straight-bar base (29), the optically focused bright spot is just in time aimed at the point sample place, so just, can clearly observe syringe needle in the point sample process or capillary head and thin layer plate near distance, be convenient to regulate subtly.(21), (22), (23), (27), (28), (29) are the basic building block of sample applicator frame.This frame can move arbitrarily along cross slide way (30), and also longitudinally guide rail (16) moves arbitrarily, and (13) are the cross slide way side plate.This device panel (11) front end is equipped with horizontal scale (7), two avris are equipped with vertical scale (14), (18) for vertically moving pointer, this pointer is contained in cross slide way side plate lower end, just in time parallel with the sample applicator head, thereby can satisfy the point sample spacing of virtually any size, and can be on the piece plate bilateral point sample.Laterally and the parallel longitudinal degree all＜± 0.3mm, uniformity coefficient＜0.2mm.(9) be circular or the bottle groove of other geometric configuration, can lay little measuring cup that sample is housed, small beaker etc., sampling is directly carried out, simple and convenient on the machine box.This device has designed an aperture in face plate center, in the time need carrying out point sample to the circular slab that is used for radial film, as long as load onto circular point sample dish (15), its dish axle (33) is inserted aperture can carry out the work.Heated at constant temperature plate by temperature controller control is housed below the panel, is used for directly heating thin layer plate.Need the time spent to open, can quicken the sample spot solvent evaporates like this, make point sample not be subjected to seasonal effect again, overcome formality with the volatilization of hair dryer air-supply accelerated solvent, and make the point sample spot obviously reduce, this is for accuracy of detection, and the raising of separating effect and the point sample that satisfies efficient thin layer require of great advantage.
By description to above-mentioned device basic structure, we can find, the utility model carries out point sample work for ease of the analyst and considers very carefully, thoroughly having overcome staff shakes and the eyesight deficiency naturally, the defective phenomenon of the point sample of lacking experience and causing, and make the thin layer plate of various different components, difformity (circular, square) all can obtain best application, thereby improved the precision of stratographic analysis.
Further specify technical spirit of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing 1 is the structural representation of this device.(24), (25) are lamp house among the figure, and (26) are snakelike desk lamp pipe, and (1) is power switch, (2), (3) are 254mm and 365mm uviol lamp switch, (4) be the heated at constant temperature switching plate, (5) are the temperature control potentiometers, and (6) are daylight lamp and small spotlight switch.
