Sample Vaporization

It is not clear what happens to the sample inside the injector. Almost certainly it enters as liquid droplets. Although it is widely assumed that vaporization proceeds almost instantaneously, it is unlikely that enough energy is available, certainly in the carrier gas, to supply the latent heat required. If the liquid sample hits the wall of the injector, instant evaporation of the solvent in contact with the wall probably forces the sample away from the wall, i.e. the source of heat. Even if the sample is injected into a hot packing only a small amount of heat is available and the sample probably evaporates quite slowly.
