Siemens has developed a comprehensive concept for energy systems worldwide – the first such concept that takes into account not only technology but also the areas of regulation and social engagement.


The MicroSAM is a miniaturized process gas chromatograph (GC) in an Ex d enclosure. Through consistent use of microsystem technology (silicon wafer technology), all analytical components are concentrated in the smallest possible area. The design particularly enables a distributed installation close to the process.


  • Fast determination of nitrogen in acetylene for process control
  • Hydrocarbon analysis of starting product (LPG) of a cracker
  • Hydrogen analysis in recycled gas and other process gases
  • Trace analysis of impurities in acetylene from a cracker
Data Sheet


The SITRANS CV gas chromatograph (GC), which is based on the innovative analytical technology of the MicroSAM, is an analyzer that has been specially developed for natural gas analysis.


  • Analysis of bio-natural gas in preprocessing plants
  • Analysis of natural gas in liquefaction and regasification plants (LNG Regasification and Storage)
  • Determination of calorific value in natural gas for power plants, in gas transfer stations, or during turbine optimization

MAXUM edition II

The MAXUM edition II is a universal process gas chromatograph for flexible process applications with a wide variety of analytical possibilities. The MAXUM edition II combines various functional modules with a flexible oven concept and can therefore also optimally solve complex applications.


  • Monitoring of benzene in styrene in the ppb range
  • Traces of residual gases in ultra-pure gases
  • Crack gas analysis
  • Fast determination of benzene in naphtha
  • Determination of halogenated hydrocarbons
  • Wastewater monitoring with PGC and stripper
