1. A method for normalizing laboratory instruments with pure dyes, comprising:
providing at least one reference instrument and a test instrument, each instrument comprising at least one excitation filter and at least one emission filter arranged in pairs;
providing a plurality of pure dyes, each dye comprising a fluorescent component and contained in a pure dye plate comprising a plurality of wells;
generating fluorescent spectra from the reference instrument and the test instrument for multiple pure dyes across multiple filter combinations;
creating a pure dye matrix, Mref, for the reference instrument and a pure dye matrix, M, for the test instrument;
calculating correction factors for each filter pair and multiplying the correction factors by the pure dye spectra;
normalizing the corrected pure dye spectra;
generating multicomponent data.
