<p>[QUOTE=&quot;desertgem, post: 1038979, member: 15199&quot;]As far as detecting acetone, according to published documents, including various biochemical and MSDS,&nbsp; <span style="color: green">pure</span> acetone evaporates 100% with no residue. Impure acetone ( fingernail polish removers, etc., can produce residue. Acetone does not produce any chemical bonding with the metal.&nbsp; I find it very very difficult to believe that acetone would remain on a coin even if said coin was hand delivered at a show. IMO, yes they could detect acetone, but there wouldn&#039;t be any there if pure acetone was used on the coin. The equipment is nothing special that most university labs don&#039;t have something similar or better. </p><p><br /></p><p>Also a good % of Americans have acetone as a component of their breath, urine, and perspiration ( especially undiagnosed or untreated diabetics, as well as byproducts of various prescription and OTC treatments, so most likely there would be many false alarms.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
