A fine-tipped marker or pen works best for chromatography as it can produce clear and precise lines on the paper, allowing for accurate separation of the pigments. It is important to use a water-soluble ink that will dissolve in the solvent used for the chromatography process.
Markers contain water-soluble pigments that are designed to dissolve in water, causing them to spread and change color when they come in contact with water. This effect is due to the water breaking down the pigments and releasing the colors from the marker onto the paper.
While we perceive a black marker as black, in reality, the ink itself is a combination of different colored pigments that appear black when mixed together. Pigments are often used to create the black color in markers, rather than a single black pigment.
Marker pen ink typically contains solvents (such as water or alcohol), dyes or pigments, resins or binding agents, and additives for smooth flow and durability. These ingredients work together to create a colorful and long-lasting writing or drawing tool.
"un marqueur"
One of the best ways to get pen and marker out of the interior of a car is to use a magic eraser. The erasers are very economical.
marker (as in indicator) = samán (סמן)marker (as in a felt-tip pen) = márkehr (מרקר)marker (as in something that emphasizes) = madgésh (מדגש)
A Sharpy fine point marker is good. It does not erase easily.

A permanent marker

When using a white marker pen for drawing, shake the pen well before use, test it on a separate piece of paper first, apply multiple layers for opacity, and store the pen horizontally to prevent drying out.

Definutly the marker. It is most likely felt tipped where as a pen is most likely ball point. The felt tip will dry out the fastest. Definutly the marker.
