I am trying to run several samples of very heavy petroleum which are waxy on GC. However due to waxy nature of the samples I cannot dissolve them in a solvent such as CS2 or DCM, and they don't get liquid at ambient temperature. Only way I could think of was to place them in a water bath. However it did not work either since as soon as I pull them away from the hot water bath samples got extremely viscous (even solid). Is there anyone who can help me out about this manual injection of those waxy samples problem?
Thanks in advance.
