Using MonoTrap RGC18 TD and Sampling tube (TenaxTA 150 g) were used as sampling media to compare.
Following the analysis condition, it found sampling tube performed better sensitivity for low boiling point components, such as Toluene and Xylene. On the other hand, MonoTrap performed better sensitivity for hydrocarbons, such as Hexadecane and the medium to high-boiling components (Methylbenzothiazole and Phenanthrene). Especially when placed on the hairbrush, the sensitivity performed higher.
When using sampling tube, it is possible to sampling the entire amount of volatilized compounds in Tedlar Bag. Therefore, it could perform a good sensitivity for easily volatilized compounds.
When using MonoTrap, it can be sampling as a position close to the sample, therefore it is able to improve the sensitivities for difficult-to-analyze compounds.
