Abstract
The utility model relates to a manual sample application auxiliary scale of thin -layer identification belongs to an appurtenance for the experiment. Peg graft with the middle part of supporting shoe is fixed respectively in the main part both ends that have the scale, there is the recess that is used for fixing a position the thin layer plate on the surface that should have the main part of scale. The advantage is novel structure, can make the sample application operation quick, accurate, and the sample application interval is obviously controllable, improves work efficiency. It is perpendicular with the thin layer plate to be convenient for for the sample application capillary, is favorable to protecting the thin layer plate to avoid the cross contamination of operator's hand among the operation process, and easy operation is easy to learn and use, has guaranteed the sample application quality, reduces operator's counter point apart from the influence of inequality, is the manual sample application appurtenance of ideal.
Description
Technical field
This utility model belongs to a kind of experiment aid.
Background technology
Thin layer chromatography point sample is the committed step that sample is successfully separated with accurate quantitative analysis, and manual point sample requires that operator has rich experience and technical ability, is otherwise difficult to reach the requirement of TLC separation. Currently without relevant aid, causing that point sample spacing is uneven, lamellae is subject to the contact stain of operator's hand, makes arraying quality be affected.
Summary of the invention
This utility model provides a kind of thin layer to differentiate manual point sample auxiliary scale, and uneven to solve the point sample spacing that manual point sample exists at present, lamellae is subject to the contact stain of operator's hand, makes the affected problem of arraying quality.
This utility model adopts the technical scheme that: with the grafting fixing with the middle part of a bracer respectively of graduated main body two ends, there is the groove for positioning lamellae on this surface with graduated main body.
This utility model one embodiment is: have the point sample labelling being evenly arranged protruding in the side of groove.
This utility model one embodiment is: the distance between two bracers is 15 ~ 17cm.
This utility model one embodiment is: the distance at the edge of groove and main body 1 is 1.0 ~ 1.2cm.
The utility model has the advantages that novel structure, can make printing operation quickly, accurately, point sample spacing is substantially controlled, improves work efficiency. It is easy to point sample capillary tube vertical with lamellae, operating process is conducive to protection lamellae from the contact stain of operator's hand, simple to operate; it is easy to learn and use; ensure that arraying quality, reduce operator to point from uneven impact, be desirable manual point sample aid.
Accompanying drawing explanation
Fig. 1 is the structural representation that this reality is novel;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is that this utility model uses state reference map.
Detailed description of the invention
With the grafting fixing with the middle part of a bracer 2 respectively of graduated main body 1 two ends, there is the groove 3 for positioning lamellae on this surface with graduated main body 1.
This utility model one embodiment is: have the point sample labelling projection 4 being evenly arranged in the side of groove 3.
This utility model one embodiment is: the distance L1 between two bracers 2 is 15 ~ 17cm.
This utility model one embodiment is: the distance L2 at the edge of groove 3 and main body 1 is 1.0 ~ 1.2cm.
This utility model one embodiment is: the height H of main body 1 bottom surface is 0.4cm.
Using method: as this utility model is placed on above lamellae 5 base by Fig. 3, the edge, base allowing lamellae during point sample overlaps with groove 3, so can ensure that point sample position is from lamellae base 1.0 ~ 1.2cm, point sample labelling is raised with and helps sample and reference substance intersection point sample, labelling relevant position, scale in main body 1 also can play reasonable distribution point sample spacing, successively the effect of point sample.
