Studying cartilage in SEM

I just spoke with this fellow -- he says that he will be doing the CPD
at Beckman (good) and SEM here. He needs a field emission system for
his work and they do not have one there (??) Sounds like a valid reason
to me. He plans to be using the SEM for only a few weeks and has
scheduled to be in the next SNF Training class. I would think that if
the sample has undergone critical point drying and sputter coating, that
there's little likelihood of contaminating the SEM, so this should be
SpecMat-approved. Sound OK to everyone?
