The identity of the unknown ink is based on the component of the dye coloring, which is based on the difference in the diffusion coefficient over the fixed phase
Chromatography is one technique for separating mixtures into its constituent components based on the principle of stationary and mobile phases.
Generally used to separate ink is paper chromatography. Where the stationary phase is paper and the mobile phase is solvent/sample. The ink on the pen is a mixture of several dyes. The absorbed solvent will separate the ink dye into several spots that indicate the constituent components of the dye from the ink
The separation of the ink mixture is based on the component speed.
Components that are less soluble in the mobile phase will be left behind, while those that are more soluble will move faster
When the solvent rises, the ink will also carry over, so the mixture of ink components will separate.
Paper chromatography is liquid-liquid chromatography because solvent as the mobile phase, and the fixed phase is water in a paper
Chromatography itself is part of the separation of mixtures such as centrifugation, distillation, sublimation, evaporation, or critalization

Answer:
The identity of the unknown ink depends on the part of the color shading, which depends on the distinction in the dispersion coefficient over the fixed stage
Further Explanation:
Chromatography:
Chromatography is one system for isolating blends into its constituent segments dependent on the standard of stationary and portable stages.
Paper chromatography:
For the most part used to separate ink is paper chromatography. Whereas the stationary stage is paper and the mobile phase is solvent/sample. The ink on the pen is a blend of a few colors. The consumed solvent will isolate the ink color into a few spots that demonstrate the constituent segments of the color from the ink
The division of the ink blend depends on the segment speed.
Parts that are less solvent in the versatile stage will be deserted, while those that are progressively solvent will move quicker
At the point when the solvent ascents, the ink will likewise continue, so the blend of ink segments will isolate.
Paper chromatography is fluid chromatography since solvent as the portable stage, and the fixed stage is water in a paper.
Chromatography itself is a piece of the partition of blends, for example, centrifugation, refining, sublimation, vanishing, or crystallization.
