If an ink pen is used in chromatography, the ink may dissolve and separate into its component colors as it travels along the chromatography medium. However, this could lead to inaccurate results if the ink contains components that are not soluble in the chosen solvent, or if the ink itself is not suitable for chromatographic analysis. Additionally, the dye in the ink could interfere with the separation process and obscure the identification of the intended substances. Thus, using an appropriate marker or solvent-based dye designed for chromatography is essential for accurate results.
Depending on the ink and the solvent used for the chromatography, the ink might also migrate and be separated into its components or smear over the paper. With the graphite of a pencil, this will not happen.

Paper chromatography is a technique used to separate and identify components in a mixture, such as ink. A small spot of the unknown ink is placed on a strip of chromatography paper, which is then placed in a solvent. As the solvent travels up the paper, it carries the ink components at different rates, creating distinct spots. By comparing the resulting pattern of spots (the Rf values) with known inks, one can identify the unknown ink based on its unique chromatographic profile.
Ink chromatography can be used in forensic science to analyze pen inks and determine if two or more inks are chemically similar, aiding in forgery detection. By separating the ink components, analysts can compare the ink profiles from different sources to provide evidence in cases involving counterfeiting or document fraud.
You can use the filter paper or chromatography paper to separate the different components in black ink.

Chromatography works to separate particles of ink by exploiting differences in solubility between the ink components and the mobile phase (solvent). As the mobile phase moves through the stationary phase (usually a paper or column), it carries the ink components at different rates based on their solubility. This differential movement results in separation of the ink particles into distinct bands or spots on the chromatography paper.
One way to determine if a sample of ink is pure is by conducting a chromatography test, which separates the components of the ink. If only one component is present, the ink is considered pure. Other methods, such as spectroscopy or chemical analysis, can also be used to determine the composition of the ink and confirm its purity.
I recommend paper chromatography.
A lead pencil can be used to lightly mark chromatography paper to help identify and track samples during the process. However, it is important not to press too hard or use ink as it may interfere with the chromatography separation.
Chromatography is used in blood to determine whether it is contaminated with alcohol and things like that. It can be also used to find out if cocaine etc. is in your urine and lead in water. This uses a colour chart to see what chemicals have been used and added up make a compound, then you can find out that it is alcohol, lead etc.

because the ink from the base line would mix with the ink blobs you are testing... its a bit obvious. and NEVER EVER draw your base line under the water. cause that would mean the blobs you are testing mix in the water and you dont know what colours the inks split into. depending on your age this is in your gcse and a level exams i think.
