The image illustrates a simple representation of a chromatography paper with three sample spots labeled X, Y, and Z at the bottom. These are marked with vertical lines crossing a dashed line, indicating their initial positions. - The paper contains several black circular spots of varying sizes. - The spots are vertically aligned upwards, demonstrating their movement and separation due to chromatography. - There is a dashed line near the top edge of the paper, suggesting the solvent front indicating the farthest point reached by the solvent. The diagram likely represents the results of a chromatography experiment used to separate and analyze components in each sample (X, Y, Z). The different distances traveled by the spots correspond to different affinities of the components to the stationary and mobile phases, aiding in their identification and characterization.

The image displays a rectangle divided horizontally into three sections by dotted lines. Within the middle section, there are two dots. At the bottom of the rectangle, two labels "A" and "B" are positioned side by side, separated by a short vertical line. The labels likely indicate specific points or positions along this section. This diagram could represent a simplified model or chart, with the dots potentially indicating specific data points or locations on this chart. The inclusion of dotted horizontal lines may suggest divisions or thresholds relevant to the context being illustrated.
