WebSolvent in the gas phase limits ionization by ESI to molecules more basic than the solvent. The exception is photoionization (which is not acid/base ionization) but nonetheless mediated by solvent. Removing solvent and water vapor from the ionization region increases types of compounds that can be ionized at atmospheric pressure. WebPhase separation as shown in Figure 6.12 is fundamentally based on a thermodynamic process which is used for preparing interwoven, nanofibrous scaffolds in tissue engineering.

Reversed phase SPE separates analytes based on their polarity. The stationary phase of a reversed phase SPE cartridge is derivatized with hydrocarbon chains, which retain compounds of mid to low polarity due to the hydrophobic effect. The analyte can be eluted by washing the cartridge with a non-polar solvent, which disrupts the interaction of the analyte and the stationary phase.
