Q
why do pigments move faster than others
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
The mobility of pigments in a medium, such as in paper chromatography, primarily depends on their molecular properties and interactions with the solvent. Pigments that are more soluble in the solvent used will move faster and further because the solvent can carry them more easily along the medium. Conversely, pigments that have stronger interactions with the medium, or are less soluble, move slower due to being more strongly retained. Additionally, the size and molecular weight of the pigments can affect their speed; smaller or lighter molecules generally travel quicker than larger or heavier ones. This principle allows for the separation and identification of different pigments based on their unique travel distances in a given solvent and medium setup.
