ABSTRACT:
A calibration method and device for a fluorescence spectrometer which uses fluorescence from a homogeneous solid state standard as the source of calibration fluorescence and wherein the solid state standard may be built into the optical scanner and the calibration may be automatically performed as a routine step when using the optical scanner. A gold standard establishes fluorescent units, and the fluorescence spectrometer is calibrated by reference to calibration standards, such as calibration rubies, which are themselves rated against the gold standard and built into the fluorescence spectrometer to provide an unchanging reference to the gold standard and by which simultaneous calibration of two or more channels of a multi-channel fluorescence spectrometer may be accomplished, including automatically calibrating a multi-channel optical scanner when it is turned on to achieve an acceptable level of sensitivity in each channel and to adjust for any relative shift in sensitivity between the channels.
