The separator and its associated equipment

The characteristics of the separator and its associated equipment used for hydride and cold mercury vapour generation are dictated by the state of the sample. 

Ideally, the unit used to isolate the gas formed from the liquid or suspended phase (whether a hydride or metal vapour) should meet several requirements, namely  

Separators based on diffusion of the gas phase across a permeable membrane, which are known as dual-phase gas diffusion separators , can be of two types, namely  

Solid sample treatments involving the removal of volatile species 

The separator for solid samples depicted in Fig. 4. IF is a dismountable device where the lower part is lightweight as the sample is weighed in it. The lower part is connected to the rest and the reagents are inserted through a septum (simultaneously with the start of stirring and passage of the stripping gas).
