Catherine Sieracki asked about MicroChamber paper from Conservation Resources.

MicroChamber paper works.  It's an excellent scavenger.   I've talked with
Bill Hollinger several times and also with a well-known conservation
scientist (no name, because I don't have his permission for the list) who
is quite amazed at the paper's capacity to absorb deterioration byproducts.
CRI licensed Bainbridge to use the MC technology in their mat boards- look
for "Art Care" or "NT" (New Technology) on the backs of the mats.  I have
some of the MC emulsion which is described as "Activated carbon in an
aqueous dispersion with calcium carbonate and acrylic polymer."  I hope
this helps.
