LPG is odorized to alert in case of leakage. Typical sulphur containing odorants area mercaptans such as TBM and EM, THT, organic sulphides such as DMS or mixtures. Gas Chromatography can provide the quantitative speciation of these odorants in LPG to check the effectiveness of the odorization.
However, there is a need to perform these analyses directly from the liquid phase because the odorized liquid vapors may not be uniform.
An energyMEDOR® auto-GC analyser with a LPG sampling valve can be used to overcome this problem.
