A comparison of the mass spectra obtained using heated single capillary and multicapillary (seven capillaries) inlets for a) 1μM of Leucine Enkephalin on the single capillary, b) 1μM of Leucine Enkephalin on the multicapillary, c) 1μM Reserpine on the single capillary, d) 1μM Reserpine on the multicapillary, e) 0.25 μM of Bradykinin on the single capillary, f) 0.25 μM of Bradykinin on the multicapillary, g) 1μM Ubiquitin on the single capillary and h) 1μM Ubiquitin on the multicapillary. All other experimental parameters were kept similar except that the emitter tip position and electrospray voltage were optimized in each mass spectrum to give optimum stable signal.
