Figure 1 : CCM RPMI 1640 analysis on three REBEL devices with 20 replicate measurements per device. Analyte recovery was calculated by comparing the measured amino acid concentration to the published classical RPMI 1640 formulation concentration. This graph shows measurement accuracy with ¡¾20% analyte recovery highlighted with grey background, and reproducibility as error bars with %RSD values at the base of the column.
