Yeah, I guess I thought they might have something a bit more spectographically advanced to determine molecular makeup rather than just backscatter (something that might distinguish teflon with it's abundance of fluorine from organic matter). It seems like a much more crude instrument than I thought. For millimeter wave, I'm pretty sure the teflon wouldn't work though, since the millimeter wave machines are likely tuned for organic makeup rather than just backscatter.
