Comparison of Mainstream Smoke Yields between Linear and Rotary Smoking Machines and Evaluation of "Super Pad" Extraction for Linear Smoking Machines

Chem Res Toxicol. 2021 Jul 19;34(7):1713-1717. doi: 10.1021/acs.chemrestox.1c00074. Epub 2021 Jul 6.

Abstract

Two-tail t test statistical analyses of International Organization for Standardization nonintense and Canadian Intense mainstream smoke yields of total particulate matter, tar, nicotine, and carbon monoxide from cigarettes show that mean quantities are generally higher for a linear smoking machine at a 95% confidence level but a rotary smoking machine has better precision. A novel "super pad" analysis concept combines four smaller filter pads from a linear smoking machine, resulting in increased mean constituent yields and reduced variability. Although measurement variability is still greater than that of rotary machines, super padding may be useful to reduce the variance caused by linear smoking machines.
