"These results indicate that decreased efficiency of aerosol production, in terms of mg/watt, at higher power levels might indicate overheating of the atomizer leading to elevated levels of aldehydes in the aerosol. This effect may be due to insufficient liquid supply to coil, leading to production of excess heat instead of conversion of the liquid into aerosol. From a thermodynamic stand point, formation of the aerosol and liquid decomposition can be viewed as competing pathways, and decomposition, involving bond breaking, would be in thermal competition with formation of the aerosol since both pathways would absorb available heat from the atomizer coil."
"An increase in the efficiency of aerosol production with increasing power supplied to the atomizer was correlated with lower levels of aldehydes in the EC aerosol."
"...some devices far more capable than others of maximizing liquid aerosolization while minimizing thermal decomposition at higher power levels."
" At the conclusion of this study, the coil for Device 1 was examined and found to be charred, an indication of thermal decomposition."
"The high levels of aldehyde formation seen in Device 1 could be due, in part, to the formulation or viscosity of the test liquid used in this study. The composition of the liquid may have an impact on the rate at which liquid is transferred to the coil and also the formation of aldehydes."
Δηλαδη οσο πιο καλη τροφοδοσια υγρου εχεις στην αντισταση ωστε να παραγεται ατμος και να μην "τρως καμενο" τοσο λιγοτερες αλδευδες εκλύονται.
