We developed an odor sampling bag system using Nalophan plastic to create a closed headspace with air as the carrier medium, eliminating solvent-related variability and ambient air dilution. In 2 independent experiments, 15 participants each rated the perceived intensity of 7 concentrations of benzaldehyde and 2-heptanone using both gas-sampling bags and glass jars. Bags produced higher maximum perceptual intensities (P &amp;lt; 0.001) and greater test\u2013retest reliability than jars (experiment 1: r = 0.89 vs. 0.81, P &amp;lt; 0.001; experiment 2: r = 0.86 vs. 0.72, P &amp;lt; 0.001). Notably, the 2 tested odorants showed different maximum intensities in bags (P &amp;lt; 0.001) but not jars (P = 0.85), suggesting bags better preserve odorant-specific concentration differences. Photoionization detector measurements confirmed stable headspace concentrations over time, comparable to industry-standard Tedlar bags. This affordable, easy-to-implement method accurately delivers desired odor concentrations without requiring expensive olfactometry equipment, offering a practical solution for olfactory psychophysics research.<\/jats:p>","DOI":"10.1093\/chemse\/bjag022","type":"journal-article","created":{"date-parts":[[2026,7,27]],"date-time":"2026-07-27T13:42:43Z","timestamp":1785159763000},"source":"Crossref","is-referenced-by-count":0,"title":["Odor
