About this document

Ink Chromatography Experiment Guide by api-263909505 is a document available to read on EtoBox.

Ink chromatography can be used to analyze mixtures like ink and separate its colored pigments. In this technique, a small dot of ink is placed on a paper strip and the strip is placed in a solvent like water. The solvent carries the pigment molecules up the paper at different rates based on how well they dissolve. This produces a chromatogram showing the different pigments as bands of color. Forensic scientists can use ink chromatography and calculate retention factor (Rf) values to match crime scene sample
