Abstract
A method for correcting for light scattering affects obtained from a sample to which a fluorophore has been added. In accordance with the invention, a sample to which a fluorophore has been added is irradiated with light in the adsorption band of the fluorophore such that the fluorophore emits light at a different intensity. By manipulating the pH of the sample, and obtaining both pre- and post-manipulation emission light intensity readings, the value of the reading attributed to 'light scattering' can be determined, such that correction of an erroneous fluorescence reading can be obtained.
