SD values for the 6 detected peak masses as obtained from the 20 samples: (a) saliva samples showing two peaks from the common plate with a lower SD than that of the coated plate; (b) bacteria samples showing only one peak from the common plate with a greater SD than that of the coated plate; (c) serum samples showing that all peaks from the coated plate were lower than those of the common plate.
