I am trying to do a quantitative analysis on the amount of paraffin wax contained within a sample of toner (for a copy machine).  I do not have a GC available, only a DSC and FTIR.  Does anyone have any suggestions on how to extract the wax and quantitate the amount?  The toner generally contains a resin (polyester), a paraffin wax, and charge control agent.

Most of what you describe probably wont dissolve in pentane apart from the paraffin.

A soxhlett extraction using a light petroleum such as pentane (on dry toner, i.e. no water) should fully remove the paraffin, which you can test with IR then the thimble can be dried and the difference weighed.
