Or fire up the mass spectrometer you picked up on eBay (e.g. 290368922457).

Err, yes... But not everybody is lucky enough to have one...
More seriosuly, there is a worrying tendency in all sorts of areas to
throw a complex solution at a problem rather than actually thinking about
the problem. As a book I've been reading says 'There is no shortage of
information, but people don't know how to THINK anymore'. It worries me...
And to be honest, even if I was going to tuse a mass-spec for this, I
would still try some simple tests (such aas those I suggested first), so
I can see if the results from the complicated machine make sense
