High performance thin-layer chromatography (HPTLC) offers many advantages over conventional separation techniques when applied to complex samples. The Column interviewed Gertrud Morlock from Justus Liebig University Giessen in Germany, on her current research, which involves hyphenating HPTLC with multiple analytical techniques.

Planar chromatography celebrates its 70th birthday. The technique dates back to 1938 when, at the Pharmaceutical Institute in Kharkov, Ukraine, N.A. Izmailov and M.S. Shraiber first devized a circular thin-layer chromatogram,1 which was called spread layer or spot chromatography at the time.
