Abstract
A luminometer for analyzing genetic or non-genetic maaterial comprises an optical chamber for receiving and holding a vial of the sample material in a dark environment. A pumping system mounted in the luminometer pumps reagents into the vial to cause the sample material to luminesce, and a sensor is positioned in the dark environment relative to the vial to detect the luminescence. Instantaneous intensities of the luminescence are sequentially sampled at set intervals of time during a preselected time period and summed by a microprocessor to generate a signal that is descriptive of the constituents of the sample.
