PAHs analysis was carried out using an automatic thermal desorber
unit (Turbomatrix 150 ATD, Perkin Elmer S.L., USA) coupled by a fused silica capillary transfer line (5 m length x 0.32 mm I.D.) to a GC/MS detector (Clarus 500, Perkin Elmer S.L., USA).
consist of low-temperature components of zone 3 as well as zones 4 and 5.
Clariant's EQ-Pak packets and EQ-Can canisters are specially engineered sorbents that can act as humectants (desorbers
) and desiccants (adsorbers) simultaneously, maintaining a particular equilibrium relative humidity (ERH) inside product packaging.
In their most basic forms, thermal desorbers
heat the sample, which is then carried directly to a gas chromatography column.
