Frequency distribution of precision of C. reinhardtii metabolite profiling; N = 9; study 1. Blue: steel ball disruption + extraction by water/isopropanol/acetonitrile (WiPM). Orange: glass bead + methanol/chloroform/water (MCW). Both identified and unidentified metabolites were used as reported by the mass spectral database BinBase. CV = coefficient of variance.
