Linearity experiment
NettetPerforming a linearity of dilution experiment can also be done via preparation of several dilutions of a sample with low level concentration of analyte and then spiking the same known amount of analyte into each one before testing and assessing assay recovery by comparing the observed and expected values of non-spiked and/or undiluted samples.
