What a great development to learn this---I, too, would value some source material for the community to deepen our knowledge drnocturne-- and pete, perhaps you can still continue to help us all by sending samples to our forum lab experts for formal analysis-- that alone would be a huge service! We as a community could orchestrate a group donation/fund to take on the cost to make it happen? Your hard work is so deeply appreciated!! I don't believe for a moment that it is in vain
