Because ink will run.
Pencil is commonly used to mark TLC (thin layer chromatography) plates because it is chemically inert and does not interact with the substances being separated. It also adheres well to the surface of the TLC plate and does not dissolve in the developing solvent, allowing the spots to remain visible throughout the separation process.
Pencils are preferred over pens when marking TLC plates because pencil marks are less likely to smear due to the solvent used in TLC development. Additionally, pencil marks can be easily erased and corrected if needed without affecting the results of the analysis.
The only one who died in TLC is Lisa Lopes.
Using a ballpoint pen to mark the spotting line and positions on a TLC plate may cause interference with the separation of compounds during the chromatography process. The ink from the pen can mix with the sample and affect the movement of the compounds on the plate, leading to inaccurate results. It is recommended to use a pencil or specialized TLC pens that do not interfere with the separation process.
No stupid only three TLC
Ball point pens have water-based ink that can dissolve and run, smudging the compounds being separated on the TLC plate. This can affect the accuracy and readability of the results. It is best to use a pencil to mark TLC plates as it will not interfere with the separation process.
Keeping the beaker covered with Parafilm helps prevent the solvent from evaporating too quickly, which could lead to uneven solvent front movement on the TLC slide. This ensures a consistent and accurate separation of compounds on the TLC plate.
No, Beyonce was never apart of the group TLC. She was in Destiny's child but never TLC

Because the ink from the pen will run and smear during the chromatography but the pencil mark is not affected.
