Hey, good to hear from you!  I was stoked when I ran across that mass spec you'd posted, it really helped to give some substance to the topic.  Sorry to hear about your friend  .

I'll update the document some time this weekend to reflect that it was LC/MS, not GC.  I don't think it makes that much of a difference... except for the curious fact that the red material appears to be primarily DMT according to GCMS, while we tend to see these other compounds with LCMS.  I'm not sure why.

So I've been wondering: maybe it's been too long for you to have any idea, but did that sample come from an acid/base or straight-to-base extraction?
