Any suggestions on an extraction method? With soil samples we use hexane, but I don't think that's going to work with the caulk. I'm also not exactly sure what kind of caulk it is, its grey so Im thinking its not just silicone.
With especially dirty soil samples we'll clean up the sample using sulphuric acid, copper and florisil, but that doesnt seem like such a great idea for the caulk samples.
