Witryna1 kwi 2024 · High spatial resolution imaging of biological tissues using nanospray desorption electrospray ionization mass spectrometry 13 November 2024 Ruichuan Yin, Kristin E. Burnum-Johnson, … 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 … Zobacz więcej 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, Zobacz więcej The electrosprays operated at low flow rates generate much smaller initial droplets, which ensure improved ionization efficiency. In 1993 Gale and Richard D. Smith reported significant sensitivity increases could be achieved using lower flow rates, and … Zobacz więcej • Cole, Richard (1997).
