Volatile organic compounds: sampling methods and their Generally, methods for volatile organic compounds sampling include collection of the whole air or preconcentration of samples on adsorbents. All the methods vary from each other according to the sampling technique, type of sorbent, method of extraction and identification technique.
As a result, high levels of volatile organic compounds (VOCs) can be present in the product, which pose an inhalation risk to humans. To identify potential levels of VOCs in wallpaper samples, a method was undertaken, targeting 35 volatile organic compounds using a PerkinElmer TurboMatrix™ 650 ATD and PerkinElmer Clarus® SQ8 GC/MS, with results and methodology introduced in this study.
