Abstract

The feasibility of forward-scattering degenerate four-wave mixing (F- D4WM) for detection in micro-column (internal diameter 0.3 mm) liquid chromatography (micro-LC) is studied, using the separation of 1-amino-9,10- anthraquinone (I-AAQ) and 2-amino-9,10-anthraquinone (II-AAQ) as a model system and utilizing the 514 nm line of an argon-ion laser. Though the F- D4WM signal can be detected on a virtually dark background, in practice background reduction is of utmost importance. Background reduction by means of a mechanical chopper and a scanning confocal Fabry-Perot interferometer (CFP) are compared both experimentally and theoretically. Using the CFP set- up, an injected concentration limit of detection of 3.10
