Fraction | Eclipse | 1R5F | Merit Ultralight | 1R4F |
---|---|---|---|---|
*Selected fractions using FTC smoking parameters (one 35 ml, 2 second puff every 60 seconds). For Eclipse, the FTC protocol was modified, since the device does not shorten as it is consumed. Instead, 15 puffs were taken, which was sufficient to exhaust the fuel element under these testing conditions. It is unclear which version of Eclipse is represented in these data. | ||||
†By definition, “tar” is total particulate matter (TPM) minus both water and nicotine. Here, “tar” consists of “soot” plus glycerin. Hence, the five fractions are not additive. | ||||
