A dual monochromator/fluorescence detector is equipped with a preparative flow cell (10-mm ID) that allows high flow rates (that is, 1to 2 L/min) without clogging. The unit offers an analytical method for detecting oil at concentrations from near saturation to well below parts per billion (ppb) levels. The detector's excitation and emission wavelengths can be preset to produce a threshold voltage for a desired range of concentration.
