Aroma compounds in scented wax candles as well as aroma and odor emissions were determined by GC/MS after direct thermal extraction and air sampling with sorbent tubes.

Data acquired using the Centri® automated multi-mode sampling and preconcentration system for GC–MS can be used to generate insights into the aroma profiles of foods.
