WebThe advent of nano-electrospray ionization (nano-ESI) has considerably extended the usability of ESI in the analytical mass spectrometric laboratory. One of the remarkable features of nano-ESI is its extremely low sample consumption. Only a few microliters of analyte solution (10–5–10–8 M) are sufficient for molecular weight determination and … Electrospray ionization (ESI) is a technique used in mass spectrometry to produce ions using an electrospray in which a high voltage is applied to a liquid to create an aerosol. It is especially useful in producing ions from macromolecules because it overcomes the propensity of these molecules to fragment when … See more In 1882, Lord Rayleigh theoretically estimated the maximum amount of charge a liquid droplet could carry before throwing out fine jets of liquid. This is now known as the Rayleigh limit. In 1914, See more The electrosprays operated at low flow rates generate much smaller initial droplets, which ensure improved ionization efficiency. … See more • Probe electrospray ionization • Laser ablation electrospray ionization • Sonic spray ionization See more • Electrospray Ionization Primer National High Magnetic Field Laboratory • See more The liquid containing the analytes of interest is dispersed by electrospray, into a fine aerosol.
