I had some fruitful discussions with the guy who will be taking my samples through their final step of analysis. Here he is next to the machine he will use. It is a GC (like I have used before), but it is modified into a 2D GC, which will be able to seperate the mutlitide of compounds in the samples so he can get enough space around the compounds to examine the carbon isotopes in a couple specific compounds. The good news is that he thinks there is a good amount of actual residue, so he won't have any problems having too little carbon to work with. The bad news is that the chromatographs are really complex and have a lot of peaks, so he needs to try to increase the seperation to get enough space around the compounds to get a clean read on them. I thought they were really difficult GC results, so it was gratifying to hear the same thing from someone with a lot more experience in the field.
