As I recall (and memory may and often does fail me) Bernie Andersen at 
PNL wrote some reports and a paper or two on particle sizing and hot 
particle detection from air filter samples.  You might try looking for 
B.V. Andersen published articles via quest as there was, I think, 
something in the HPJ.  In any event, it would seem that ARG would be a 
way to go.
