In contrast, acetonitrile cools the temperature by absorbing heat, so air bubbles are generated later, as it gradually returns to room temperature.
WebFor electrospray ionisation (ESI) reversed phase solvents (water, acetonitrile, methanol) are preferable as they favour the formation and transfer of ions from the liquid to the gas phase. Normal phase solvents (hexane, toluene, dichloromethane) cannot support ions in solution and are, therefore, not suitable for use with ESI (they can, however, be used … WebElectron impact ionization of ethylene-methanol heteroclusters: Stable configurations and mechanisms in intracluster ion-molecule reactions.
