Pen ink contains colored pigments, and it can be dissolved in water

The baseline where dyes are placed in a chromatogram is typically not drawn with a pen because the ink from the pen could potentially interfere with the separation of the dyes. Using a pen may introduce additional components into the chromatogram that can affect the accuracy and reliability of the analysis. Instead, a pencil or other non-reactive marking tool is typically used to mark the baseline.
