Figure 2
The ion flux in the source region under different conditions. The ion flux in pA with elevated source pressure (top) and no additional pressure (2 mbar, bottom) is shown for different hexapole DC offsets (x axis) and RF amplitudes. (a) Pure buffer ammonium acetate, AmAc, (b) T3 and T4 HBV capsids and (c) GroEL are compared. |
