Supercritical-Fluid Chromatography On-Chip with Two-Photon-Excited-Fluorescence Detection for High-Speed Chiral Separations

, 2019
Herein, we present the first example of microchip-based supercritical-fluid chromatography (SFC). A microfluidic-glass-chip platform with pressure and temperature control for fast and efficient on-column injection is described.
