Variable analysis
- Research cigarettes 3R4F and 1R5F (University of Kentucky, Lexington, KY)
- Nitrobenzene and 2-nitropropane deliveries
- 3 unlit clearing puffs collected after smoking was completed
- Material blanks for the vapor phase were gas sampling bags filled with approximately 350 mL of laboratory air, equivalent to 10 × 35 mL puffs, and spiked with ISTD
- Material blanks for the particulate phase were new filter pads inserted into a clean headspace vial and spiked with ISTD
- Matrix blanks for both phases were collected as normal QC samples on the smoking machine, with empty, but filtered, cigarette holders
- Research cigarettes 3R4F and 1R5F (University of Kentucky, Lexington, KY) were used as quality control (QC) samples and were included in each smoking machine run
- Matrix blanks accounted for carryover in the smoking machine and sidestream smoke contamination from cigarettes on neighboring ports

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
