WebMay 2, 2012 · 1. Volatility depends on four factors for organic compounds: 1) Branched chained hydrocarbons are more volatile than straight chained hydrocarbons. 2) The more branched an hydrocarbon is the more volatile it is. 3) Depending on the bonds i.e hydrogen bond, dipole-dipole intermolecular bond and van der Waals' forces. WebThese systematic errors can be eliminated by using closed systems and by working at low temperatures. For the determination of elements which are relatively easily volatilized (e.g. Hg, Se, As, Bi, Zn, Cd) from non-volatile matrices, we can make use of the very advantageous separation in the vapour phase (see Sections 5.4.2 and 5).
