Abstract: A simple, elegant method for the formation of a continuous stationary phase gradient for use in chromatographic separations is described. Its applicability to separation science is demonstrated using thin-layer chromatography as a test case. Gradient stationary phases were formed on activated High Performance Thin-Layer Chromatography (HP-TLC) plates using a newly developed methodology termed "controlled rate infusion". Specifically, the SiOH groups on the activated HP-TLC plates were reacted with 3-aminopropy…
