Photothermal Deflection Spectroscopy of Collected Aerosols

Future Aerosol Work We need to us an in situ apparatus to measure aerosolconcentrations side-byby-side with “conventional” equipment. In terms of understanding the signals, we need to answer– How cooperative heat transfer effects in high-sample surface density– Can we use the time-dependent signals to determine aerosol thermaland absorbance properties? Finally, can we obtain multiple aerosol signals that are asprecise as the individual aerosol measurements?
