WebCold-cathode fluorescent lamps were used for backlighting of LCDs, for example computer monitors and television screens. In the lighting industry, “cold cathode” historically refers to luminous tubing larger than 20 mm in diameter and operating on a current of 120 to 240 milliamperes. WebAs familiar examples, fluorescent paints and highlighters emit fluorescence with a clear color. Figure 1 shows a FL detector optical system. While a UV/UV-VIS detector detects light that has passed through the flow cell, an FL detector detects fluorescence emitted in the direction orthogonal to the exciting light.
