Abstract
A fluorescence detector includes a light source being positioned so that in use, radiation emitted therefrom falls on one or more fluorescing species, and a photodetector being switchably connectable between a charge integrator device and a charge disposal device. The photodetector is positionable to detect fluorescent radiation from the fluorescing species. A controller communicates with the light source and the photodetector, and is operable in a cyclic manner to activate the light source to emit radiation and connect the photodetector to the charge disposal device for a first period of time, and connect the photodetector to the charge integrator device for a second period of time after the first period. The charge integrator device is not reset from one cycle to the next.
