Abstract
The utility model relates to a thin-layer chromatography sample applying device which is characterized by comprising a sample applying needle and a sample applying bracket, wherein the sample applying needle comprises a needle tube and a needle head, and a baffle is arranged on the needle head; the sample applying bracket comprises a flat plate, a bracket frame and four bracket legs, wherein a sample applying hole which is used for allowing the needle head to pass through is formed in the flat plate, the diameter of the sample applying hole is less than that of the baffle, the flat plate is connected with the bracket frame through a clamping groove, scales are formed in one side of the bracket frame, and the bracket legs with adjustable heights can extend and retract up and down; the distance between the baffle and the flat tip of the sample applying needle is equal to that between a plane in which the sample applying hole is formed and a thin-layer plate. The thin-layer chromatography sample applying device has the advantages of simplicity and convenience in operation and no need of control over sample applying strength and is suitable for beginners to perform sample application.
Description
Technical field
The utility model relates to a kind of thin-layer chromatography spot sample device, belongs to technical field of chromatographic analysis.
Background technology
Thin-layered chromatography is a kind of important experimental technique of chemistry, field of medicaments, while using thin-layered chromatography to carry out qualitative or quantitative test, general tack spotting needle or the microsyringe of adopting carries out point sample, when point sample, syringe needle need contact with thin layer plate, but in point sample process, the dynamics of point sample is not easy to hold, dynamics is excessive, easily the coating thing on thin layer plate is punctured, cause the inhomogeneous of point sample, affect the effect of thin-layer developing; Dynamics is too small, and the Contact Thin laminate that syringe needle can not be good causes sample point sample amount very few; Meanwhile, for beginner, in point sample process, hand is easily shaken, and the more difficult dynamics to point sample is controlled, and has had a strong impact on the quality of point sample.
Utility model patent " a kind of sampling needle for thin-layer chromatography ", number of patent application 201320276138.5, a kind of sampling needle for thin-layer chromatography is disclosed, adopt the frame mode that connects moving casing and fixed sleeving by spring, making syringe needle to more easy-regulating of the pressure of thin layer plate, although this sampling needle for thin-layer chromatography has solved the uppity problem of point sample dynamics to a certain extent, but still is manual force, for beginner, be still difficult for operating.
Utility model patent " sample dripping bracket of microsyringe ", number of patent application 201120146715.X, discloses a kind of sample dripping bracket of microsyringe, adopts this support point sample convenient, material is easy to get, but this sample dripping bracket of microsyringe still comes with some shortcomings, after injector is inserted, also need manually to adjust the height of injector syringe needle and place, three leg bottoms plane, more time-consuming, in addition, plug has blocked the part scale of injector, is not suitable for carrying out sxemiquantitative or quantitative thin-layer chromatographic analysis.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming existing in prior art, provides a kind of easy and simple to handle, and without controlling point sample dynamics, applicable beginner carries out the thin-layer chromatography spot sample device of point sample operation.
For achieving the above object, the utility model adopts following scheme:
A kind of thin-layer chromatography spot sample device, comprises spotting needle and point sample support, and described spotting needle comprises needle tubing and syringe needle, and syringe needle is provided with baffle plate; Described point sample support comprises flat board, stand frame and 4 rack legs, and described flat board is provided with the point sample hole that can pass for syringe needle, and the diameter in point sample hole is less than the diameter of baffle plate, and flat board is connected by draw-in groove with stand frame, and a side of stand frame is provided with scale; Described rack leg can stretch up and down, highly adjustable; Described baffle plate equates with the distance of place, point sample hole plane separation thin layer plate apart from the distance of spotting needle tack needle point.
Described flat board is made up of transparent plastic.
The quantity in described point sample hole is at least 1.
When use, by a side of stand frame near thin layer plate, because the thickness of thin layer plate may there are differences, before point sample, the length of rack leg is finely tuned, baffle plate is equated, by the scale on stand frame one side frame apart from the distance of spotting needle tack needle point with the distance of place, point sample hole plane separation thin layer plate, can determine easily the distance between point sample position and adjacent two point of samples, complete after a point sample, by the dull and stereotyped mobile point sample of pull hole, carry out next point sample.
The beneficial effects of the utility model are:
(1) the utility model is simple to operate, because baffle plate equates with the distance of place, point sample hole plane separation thin layer plate apart from the distance of spotting needle tack needle point, therefore without the dynamics of controlling point sample, there will not be the bad phenomenon that causes point sample failure of holding because of point sample dynamics, be particularly suitable for beginner and use;
(2) stand frame is provided with scale, and the distance between convenient position and adjacent two point of samples of determining point sample is carried out point sample by the dull and stereotyped mobile point sample of pull hole, each point of sample point-blank, without pencil setting-out on thin layer plate again.
