Hi Dean,

If you vivist Stephen Quinto's web www.natural -imunogenics.com and look at
the TEM's of several of the HVAC CS samples that he has are rather large. The
TEM of the HVAC ARC CO2 cs  is not there,but it is much smaller. However the
TEM for his product is VERY impressive. It is almost invisible so I think
that if Frank would use Stephen's material for a standard then I would be
happy with his results.
