Table 3.

Percentage of control values and coefficients of variation (% CV) using microvolume spectrophometers (MV Spec), and a microvolume (MV) plate reader. The values are the average of data acquired over three days as shown in Figure 2, with the exception of MV Spec C, where the data were acquired in one day. The values in the parentheses are 1 CV (%) and the number (N) of measurements.
