The integrated exposure generation system (INEXS). The NEP is placed in a crucible in furnace #1, in which the temperature is finely controlled as well as its inlet gas composition (HEPA-filtered air or of controlled N2/O2 ratio). Upon the TD of the NEP, the released aerosol travels through three different routes (I–III) and in situ analyzed by a number of real-time instruments. Furthermore, the released aerosol can be collected and size-fractionated using the Harvard CCI. For future studies, the released aerosol can be directly guided in the in vivo inhalation chambers for toxicological analysis.
