Abstract:
1. A device comprising: at least one sample cuvette space configured to contain a sample liquid; at least one reference cuvette space configured to contain a reference liquid; a first single wavelength light source constructed and arranged to illuminate at least a portion of the sample cuvette space; a second light source at a wavelength different from the first, the second light source constructed and arranged to illuminate at least a portion of the sample cuvette space; a light detector positioned to detect light transmitted from the second light source through the sample cuvette space; a fluorescence detector positioned to receive light emitted from the sample cuvette space at a wavelength different than that emitted from either the first or the second light source; a third single wavelength light source constructed and arranged to illuminate at least a portion of the reference cuvette space; a fourth light source at a wavelength different from the third, the fourth light source constructed and arranged to illuminate at least a portion of the reference cuvette space; a light detector positioned to detect light transmitted from the fourth light source through the reference cuvette space; and a fluorescence detector positioned to receive light emitted from the reference cuvette space at a wavelength different than that emitted from either the third or the fourth light source, wherein the device is constructed and arranged to measure fluorescence of at least the sample liquid and the reference liquid simultaneously.
