MOSH/MOAH LC-GC-Analyzer

SIM offers an LC-GC analyzer for simultaneous determination of mineral oil hydrocarbons MOSH and MOAH in routine analysis.
Key component of this analysis system is the CHRONECT® LC-GC coupling developed by Axel Semrau®. It is coupled with Agilent Chromatography systems and appropriate software for the highly automated analysis of MOSH and MOAH.

MOSH/MOAH LC-GC-Analyzer

Mineral oil residues are determined by coupling liquid and gas chromatography with subsequent flame ionization detection (LC-GC-FID). HPLC is performed upstream for separation of analytes from the matrix and separation of MOSH and MOAH.
The CHRONECT® LC-GC coupling ensures that HPLC solvent quantities incompatible for gas chromatography are effectively reduced without risking discrimination or contamination of analytes.


Advantages of the LC-GC system for MOSH and MOAH determination

  • equipped with two FIDs - simultaneous determination of MOSH and MOAH fractions in a single run
  • analysis duration - results in 30 minutes, including GC detection, backflush and subsequent reconditioning
  • direct LC-GC coupling - no risk of contamination
  • no discrimination of volatile hydrocarbons
  • twice the sample throughput
  • highly automated process
  • excellent reproducibility
  • optimal sensitivity
  • upgrades available, e.g analysis of PAHs or sterols


Components of the MOSH/MOAH analyzer

  • Agilent 1260 Infinity LC with binary pump, UV-detektor and degasser
  • autosampler CTC CHRONECT Robotic
  • Agilent-GC-7890B with two FIDs
  • CHRONECT® LC-GC coupling
  • data system with controlling and evaluation software (Chronos and OpenLAB CDS ChemStation)
  • accessories and consumables


The MOSH/MOAH complete system is pre-installed and tested in the application laboratory and subsequently delivered ready for use.
