Average XRF spectra. The average of the XRF spectrum for 805 bRBCs measured with a 50 µm i.d. hydrophilic capillary (top), 78 bRBCs measured with a 25 µm i.d. hydrophobic capillary (middle), and 18 yeast cells measured with a 25 µm i.d. hydrophobic capillary (bottom). Spectra for all time points were processed as described in the text to remove the capillary background and the time points representing those times when cells were in the beam were then averaged to give these spectra. |
