For instance, formaldehyde and acetaldehyde have high solubility (i.e., 13.2 M and 22.7 M, respectively) that could increase absorption rate, and thus their collection efficiency, while benzaldehyde has a low solubility (i.e., 0.06 M) and could be less efficiently absorbed during the contact time with DNPH (i.e., 2040 min) ( Lastly, there is an emerging need of testing metallic nanoparticles in e-cigarette aerosols due to their health risks ( A limitation of this work is the limited number of e-cigarette devices and vaping conditions tested
