Although previous studies showed that direct ionization from the outlet separation channel at the chip surface with Taylor cone formation could be possible, this is probably not optimal because the ESI cone volumes are larger than peak volumes. With short...

Surface tension is directly related to the Taylor cone formation and this is related to the electric field strength applied over the fluid droplet able to deform its shape (Fig. 1.9). This tension value is...

The process of Taylor cone formation starts when the spherical surface forms an oval under the influence of increasing field strength. In turn, a sharper curvature of the oval increases the field strength. The Taylor cone forms as soon as the critical electric field strength is reached and starts ejecting a fine jet of liquid from its apex towards the counter electrode when surface tension is overcome by the...

An alternate design that uses a needleless spinneret to overcome the disadvantages of both needle-based and free-surface electrospinning, whilst controlling the Taylor cone formation is credited to Revolution Fibres Ltd [40], who scaled up this process to achieve continuous production of nanofibres from less than 100 nm to sub-micron range with more than 30 varieties of polymers. Elmarco developed similar techniques with coated wires as spinneret and recently Stellenbosch University has developed a regenerating bubble method [41] as an alternative to needle-based electrospinning.
