How do you dissolve a polycarbonate filter in acid without the use of microwave digestion?

I need to use atomic absorption spectroscopy to analyze aerosol particles gathered with a air pump-filter assembly. How do I dissolve the polycarbonate filter in acid? Would sonication in an acid medium work? Thanks
Polycarbonate will not dissolve in acid.
I would suggest CHCl3. It dissolves GREAT in CHCl3. Run a blank of (CHCl3 + polycarbonate) and subtract it from the AA spectrum of the (aerosols + polycarbonate + CHCl3).

If you go underwater, they fill with water (expected), but then the water takes 2-3 seconds to to drain out once you come up. After that, they often fog up and are therefore unusable for a few minutes.
They do float and were usually easy to find when they fell off, though they stay on quite tight. They are probably prefect for boating or whatnot, but a lot of the sports listed involve getting dunked under occasionally so I thought they could handle that better.
