As the use of electronic cigarettes continues to rise, understanding the particle emissions from both traditional cigarettes and e-cigarettes has become increasingly important for researchers. TSI instruments provide essential tools for measuring these particles, allowing for a deeper exploration of their health implications. This application note delves into how researchers utilize TSI’s mini-MOUDI™ Impactor to assess particles emitted by electronic cigarettes and traditional cigarettes.
What is a MOUDI and How Does it Measure Cigarette and E-Cigarette Particles?
MOUDI stands for Microorifice Uniform Deposit Impactor, a specialized type of cascade impactor designed to collect airborne particles for atmospheric pollution studies, visibility assessments, and other particle-related research. Unlike conventional cascade impactors, MOUDIs are capable of capturing smaller particles and do so by depositing them on substrates across eight distinct stages, organized by particle size.
Introducing the Mini-MOUDI for Smaller Volumes
To cater to the unique puff volumes produced by smokers, which typically range from 20 to 70 milliliters, TSI offers the mini-MOUDI™ Impactor. This smaller-volume version is engineered for flow rates of two liters per minute or less, enabling precise separation of smoke aerosol by particle size. This makes the mini-MOUDI™ particularly well-suited for capturing and analyzing emissions from both cigarettes and electronic cigarettes.
In this application note, "mini-MOUDI™ Impactor for Cigarette and E-Cigarette Research," we present findings from an aerosol mass study that compares the particle emissions of various cigarette and e-cigarette products, providing valuable insights into their health effects.
