On-Chip High-Pressure Picoliter Injector for Pressure-Driven Flow through Porous Media

A high-pressure (>3 MPa) on-chip injector has been developed for microchip applications including HPLC. The mechanical injector is implemented using in situ photopolymerization of fluorinated acrylates inside wet-etched silica microchips. The injector allows reproducible injections as small as 18...
