Fig. 2. Snapshots of the Taylor cone formed at the tip of the gold capillary (i.d. 200 μm) at 2.4 (a) and 3.5 kV (b) observed with the optical digital microscope system. Electrospray current intensities (1 V/division) as a function of time (200 ms/division) recorded by an oscilloscope at 2.4 (c) and 3.5 kV (d). A 0.01 M TFA water/methanol (1/1) mixed solution was supplied at a flow rate of 10 μL/min.
