Figure 4. Liquid vaporized and total carbonyl yields vs. q” for the examined ECIG devices.
Mean (STD) liquid consumed (triangles) and total carbonyl (circles) yields vs. q” (N=3 per condition). (A) SMOK TF-N2, (B) VaporFi platinum, and (C) SMOK V12-Q4. Dashed line indicates best fit for linear portion of the vaporization curve. Shaded area indicates the q” range corresponding to manufacturer’s recommended battery settings and device geometry; SMOK TF-N2 has no manufacturer recommendations (Table S1).
