The objective is to convert a sample of all liquid to all vapor instantly – without changing the composition.

It is not easy to vaporize a sample, nor is it always possible, so make sure it’s really necessary and possible before you try. You should always analyze a liquid in a liquid phase unless there are strong reasons for analyzing in a vapor phase. If you proceed with vaporization, it’s important to understand the difference between evaporation and vaporization...
