Prajwalita Das got a little love from a reaction she ran. She was using thin-layer chromatography (TLC) to check if a synthesis of a fluorinated benzoxathiin compound had gone according to her design.

Claire Hartmann-Thompson is a chemist at 3M, but outside the lab, she and other 3M scientists lead demos for students in grades 1 through 6, showcasing chemistry. In this demo, Hartmann-Thompson ...

This build uses a practice called thin layer chromatography, which separates the components of a mixture by allowing them to travel at different rates across a thin adsorbent layer using a solvent.

Thin-layer chromatography (TLC) was widely used in the 1960s and 1970s for pesticide residue analysis, but only to a limited extent since gas–liquid chromatography (GLC) and high performance liquid ...
