Figure 5

a) A comparison of the peak intensity of standard 1 [.mu]m Reserpine (m/z = 609) obtained using single capillary (filled square) and multicapillary (filled triangle) inlets. Note that the numbers next to the triangle points represents the number of open capillaries in the multicapillary inlet. b) Peak intensity of m/z 609 (Reserpine) as a function of the number of capillaries open. The electrospray emitter was pulled further from the multicapillary inlet such that the number of ions per mm2 is less than that in a). The numbers next to the triangle points represents the number of open capillaries in the multicapillary inlet. The conventional funnel was operating at 560 kHz, 70 Vp-p, and 1.6 Torr while the high-pressure funnel was operating at 1.80 MHz and between 90 and 150 Vp-p, depending on pressure.
