The Aerosol Research Lab is located at the Faculty of Engineering and Architecture at AUB. It is home to a small research group with backgrounds in aerosol dynamics, combustion, computational fluid dynamics, instrumentation, and controls. The Lab is equipped with a variety of conventional particle sampling, sizing, and generation instruments, as well as a unique digitally-controlled tobacco smoking machine that can mimic real smoker behavior. Chemical composition determinations are made offline using HPLC-MS, GC-MS, and ICP-MS instruments at the Core Environment Lab and at the Central Science Research Lab at AUB.
