VOC content determination is probably one of the simplest but most confusing
issues. It seems that everybody and their brother has their own
definition of what is a VOC. Certainly Method 24 is the standard in
determining volatile content, but isn't VOC content based on the
volatile content and it's classification under 40
CFR 51.100? 40 CFR 51.100 specifically defines a VOC as a volatile organic
compound (as defined by Method 24) which is photochemically reactive.
Am I wrong to state that a product like heptane which is volatile
according to Method 24 is not a VOC since it is not photochemically reactive?
Don't chemicals like acetone and methyl acetate become delisted as VOC's
because of their negligible photochemical reactivity? Methyl acetate
and acetone are clearly still volatile
compounds according to Method 24, but they are not VOC's due to negligible
photochemical reactivity?

Is my logic incorrect?
