Fig. 6.

Intraexperiment variability (a, c) and repeatability (b, d) for all three of the platforms according to the total reaction volume (a, b) and the effective reaction size (c, d). The data are the coefficients of variation for five measurements on each day (a, c), or for ten combined measurements from 2 days (b, d). For each genomic DNA concentration, five replicates were measured on two consecutive days. Blue line theoretical coefficient of variation for the QX100 system (with 14,000 accepted droplets), green line theoretical coefficient of variation for the 37 K array for the Biomark system (with 770 chambers), dashed line criterion for the limit of quantification, set at a coefficient of variation of 25 %
