WitrynaSeveral mass spectrometrists contacted by Chemistry World concluded that existing solutions to the coupling of nanospray mass spectrometry with separation techniques were satisfactory. ’The topic has been around for 10 years and has been solved,’ said one expert who did not want to be named. 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).
