Monitoring of liquid matrices by gas chromatography using a simplified and enhanced headspace sampling system

Chromatotec®  offers  a  headspace sampling  system designed  to  extract  representative  samples  from  the liquid phase. The vapourised sample can be pre-concentrated using a trap to achieve quantification at very low concentration  levels  (ppb  and/or  ppm).  Then,  it  is injected  automatically,  and  in  continuous  mode,  into the auto-GC   analyser.   Speciation   of sulphur   compounds or   VOCs   is   carried out   with a MEDOR®   sulphur   specific electrochemical  detector  or an FID respectively. The complete system  enables  online analysis without human intervention.

This technology can be used for a wide variety of applications in the oil and gas industry; for example, it facilitates controlling the  effectiveness  of  the LPG odourisation  process  with  DMS  and  TBM, to  alert  in  cases  of  leakage. In  aqueous mode, it  has  been  used  for  the analysis of  acrylonitrile.  This  polymer is  used  in plastics,  fibres  or  as a component of additives to enhance oil recovery. This sampling system reduces the risk of polymerisation of its monomer, acrylamide and avoids clogging columns.
