Abstract:
1. A method for validating the accuracy of automated analyzers comprising: providing a first dye solution which absorbs light of a first wavelength into one of a plurality of optical analysis cells; measuring the weight of a second dye solution which absorbs light of a second wavelength which is different from the first wavelength, wherein the weight of the second dye solution is measured based on gravimetric method; providing the second dye solution into the optical analysis cell containing the first dye solution, wherein the first and second dye solutions form a target test liquid; performing a first optical measurement based on a dye method on the target test liquid contained in the optical analysis cell to obtain an amount of the first dye solution as a first measurement result; removing the target test liquid from the optical analysis cell and transferring the same target test liquid into a microplate which is separated and independent from the optical analysis cell; performing a second optical measurement based on the dye method on the same target test liquid contained in the microplate to obtain the amount of the first dye solution as a second measurement result; and validating the accuracy of the amount of the first dye solution by performing a computational analysis to determine any deviation between and among the first and second measurement results and the weight measurement of the second dye solution.
