Photothermal Deflection Spectroscopy of Collected Aerosols

Inference from Heat Transport and Signal Modeling Predicted signals show large changes with thermal conductivity, opticalabsorption coefficients, and proximity to other aerosols. Signals are relatively stable with respect to heat capacity, especially ecially for highabsorbance samples. As might be expected, predicted signals are dependent on probe beam bgeometry and aerosol layering (vertical stacking). The big problem with FEM is derivingworking numerical models forprocessing data.
