I want simple qualitative methods to evaluate the evaporation of volatile solvents from a solution.
For example, if I have DCM in a solution and I am evaporating it, how can I know that after one hour if it is completely evaporated from solution?
Simple way weighting or observing the constant weight on the balance. Or using the headspace technique e.g. SPME and determine by GC
