Highly Tunable Stationary Phases for Micro Gas Chromatography Using Room Temperature Ionic Liquids
We deposited a number room temperature ionic liquids inside the channels of semi-packed columns and used these columns for gas chromatographic separation of mixtures containing a number of polar and non-polar compounds. We demonstrated that these columns can be used for rapid and highly efficient separation of the components of different mixtures. Moreover,...

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...

A Miniaturized Helium Photoionization Detector
This is a technique to miniaturize a Helium Photo-ionization Detector using silicon micromachining resulting in a dimension less that 2cm x 1cm x 2mm. This is suitable for universal, sensitive yet non-destructive gas sensing. Unlike its universal counterpart, the Thermal Conductivity Detector, this consumes less power (just 1.4mW) and is more stable...
