Figure 3

Green=spring, yellow=summer, red=autumn, blue=winter. n=28. (a) Median retention time deviation for the sets of MM8 profiles. X axis: Name of MM8 profile. Y axis: Retention time deviation [s]. (b) Retention time deviation plotted against retention time. X axis: Retention time [s]. Y axis: Retention time deviation [s] per profile. (c) Median mass-to-charge deviation for each profile. X axis: MM8 profile. Y axis: m/z deviation. (d) Mass-to-charge deviation plotted against retention time. X axis: Retention time [s]. Y axis: m/z deviation per profile.
