absorbance matching

in spectrochemical analysis
A procedure where the concentration of a known analyte may be determined by diluting the sample with solvent until the @A00028@ matches the @A00028@ of the analyte in the reference cell. This method is particularly useful if the @B00626@ does not hold.
