Definitions
- the invention relates to a system for improving thin-layer chromatography analysis, in particular for the analysis of chemical substances and molecular components of organisms such as animals, plants, bacteria, fungi and viruses.
- the thin polarity analysis uses the different polarity of substances / molecules.
- a stationary separating agent fixed on the thin layer chromatography plate interacts with the dissolved substances to be separated depending on their properties.
- the substances cover distances of different lengths on the separation layer of the thin layer chromatography plate. After coloring, substances can be determined qualitatively by assigning the running distance and also quantitatively by densitometry.
- a single or a system of different solvents or solvent mixtures can be used to develop the thin-layer chromatography plates. Multiple development serves to focus the gangs and improve separation.
- Separated substances can be made visible by spraying with or dipping in a colorant. In In some cases, subsequent even heating is required.
- a qualitative evaluation is made by comparing the running distance and type of coloring with known substances. Reference values are needed for a quantitative determination. For this, the substance to be analyzed must be at the same concentration in several known concentrations
- Thin layer chromatography plate can be applied as the sample. Densitometric evaluation, i.e. Comparison of the color intensities between the sample and controls enables a quantitative determination of the amount of substance contained in the sample. Since the intensity of the coloring can vary somewhat for each plate, these reference values must be reapplied to each thin-layer chromatography plate (H. Jork, W. Funk, W. Fischer, H. Wimmer: “Thin-layer chromatography, volume 1a, physical detection methods: basics , Reagenzien I .; VCH Verlagsges., Weilheim-Basel-Cambridge-New York, 1989).
- Thin-layer chromatography plates for example glass plates coated with the separating agent silica gel, can be used for material separation due to physical interactions (H. Jork, W. Funk, W. Fischer, H. Wimmer: "Thin-layer chromotography, Volume 1a, physical detection methods: basics, reagents I .; VCH Verlagsges., Weilheim-Basel-Cambridge-New York, 1989).

- the system for improving thin-layer chromatography analysis consists of an application template, a development frame, one or more holding sheets and a heating frame, which can be assigned to a thin-layer chromatography plate and one or more vertical chamber (s) with solvent / solvent mixture, in that the application template allows samples and controls to be applied at exact intervals on the thin-layer chromatography plate, the development frame enables safe and easy handling of the thin-layer chromatography plate during the
- Chromatography and detection processes inside and outside the chamber make it possible for the holding sheets not to let the filter paper, which serves to saturate the atmosphere, slide off the walls of the chamber by holding it on the wall, and the heating frame for error-free heat treatment of the thin-layer chromatography plates outside the chamber without annoying thermal bridges.

- a lining with absorbent material 4 which is mounted on the wall (s) of the vertical chamber (s) 1 and extends into the solvent or solvent mixture 3, an application template 5, a development frame 6 , one or more holding sheets 7 for fastening the absorbent material to the wall (s) of the vertical chamber (s) 1, and a heating frame 8, shown in more detail in FIG. 5, the application template 5, the development frame 6 and the heating frame 8 of the thin-layer chromatography plate 2 and the tie 7 of the vertical chamber 1 and the lining with absorbent material 4 can be assigned by the application template 5 an application of samples and controls at exact intervals on the thin layer chromatography plate
- the support bow 7 holds the lining with absorbent material 4 on the inner wall of the vertical chamber 1 in a non-slip manner and the heating frame 8 holds the thin-layer plate 2 outside the vertical chamber 1 for heat treatment without annoying thermal bridges.
- the samples and controls are applied to the thin-layer chromatography plate 2 using a pipette, a syringe with a cannula (for example a Hamilton syringe) or a glass capillary, the application template 5 shown in FIG. 1 being designed with precisely defined recesses 51 which are designed as bores can be provided for the cannula or capillary receptacle, has an outer edge 52 as a spacer, so that when the application template 5 is placed on the thin-layer chromatography plate 2, there is a precisely fitting border and parallel spacing thereof, and thus manual application in precisely defined manner Distances is allowed.
- a pipette a syringe with a cannula (for example a Hamilton syringe) or a glass capillary

- the purpose of the retaining bow 7 in the vertical chamber 1 is to fix the lining with absorbent material 4 in the vertical chamber 1 on the inner walls thereof.
- the development frame 6 which serves to hold and hold the thin-layer chromatography plate 2 to facilitate handling inside and outside the vertical chamber (s) 1.
- the development frame 6 has two supports at the lower end for receiving thin-layer chromatography plates and has a bow-shaped shape at the upper end, so that the development frame 6 can be easily grasped by hand.
- a holding tab for example made of metal, which tilts those held by the development frame 6
- the development frame 6 fits exactly into the interior of the vertical chamber 1 and holds the thin-layer chromatography plate 2 mechanically and / or by gravity at an angle of less than forty-five degrees to the vertical. This has the advantage that, in particular if development is to be carried out in succession with several eluents or if the thin-layer chromatography plate 2 is “washed” before development, the thin-layer chromatography plate 2 does not have to be touched with hands or objects when it is converted into different vertical chambers 1
- Thin-layer chromatography plate 2 in a colorant which can also be located in a vertical chamber 1, for example, ensures that the development frame 6 securely and uniformly immerses the thin-layer chromatography plate 2 in the dye bath.

Machining of the development frame 6 or retaining bow 7 from solid material or shaping by casting or hardening from the liquid phase are also possible.
- the heating frame 8 which is shown in one embodiment in FIG. 5, serves for easy handling of the thin-layer chromatography plate 2 for the visualization of latent colorations on the thin-layer chromatography plate 2 by uniform heating while avoiding undesired thermal bridges.
- heating frame 8 consists of a metal frame, for example steel or aluminum, with six support fingers 81 pointing upwards. It offers a holder corresponding to the dimensions of the thin-layer chromatography plates used (for example 20 ⁇ 10 cm).
- the six support fingers 81 - four at the corners and two in the middle of the heating frame 8 - allow both 10 x 10 cm and 20 x 10 cm thin-layer chromatography plates to be used.
- the support fingers 81 limit the space available for the thin-layer chromatography plate 2 and thus prevent it from slipping.
- the thin-layer chromatography plate 2 itself lies only on small tips on the top of the support fingers 81, so that undesired thermal bridges are reduced to a minimum.
- heating frame 8 is provided on the support fingers 81 with support points for the thin-layer chromatography plate 2, which can be formed, for example, by milled recesses. These recesses serve to fix the thin-layer chromatography plate 2 and prevent it from slipping when forces act on its side. The thin-layer chromatography plate 2 is therefore only in a punctiform and non-slip manner on the support fingers 81.
- the shape of the heating part 8 can deviate from the above embodiment, as long as the basic principle of mechanical and / or gravity-related storage of one or two thin-layer chromatography plate (s) 2 on their underside or their top side and / or their corners and / or their outside sides while minimizing heat-conducting bridges is satisfied.
