Functionalized Metal Oxides As A Stationary Phase And A Surface Template For Micro Gas Chromatography Separation Columns
This invention describes a new approach for utilizing atomic layer deposited (ALD) metal oxides as a stationary phase for microfabricated gas chromatography columns. After ALD oxide deposition, a chloroalkylsilane is utilized to deactivate the oxide surface to improve peak symmetry and retention times. Semipacked columns (1m-long, 190 um-wide with 20...
