Description

The V&F EISense is a classic quadrupole mass spectrometer with electron impact ionisation (EI-MS) and is the entry-level V&F model for online multi-component gas analysis.

Ionisation takes place at 70 eV; the mass range is 1 to 100 amu with a resolution of 1 amu.

Typical applications

  • Process monitoring of combustion plants
  • Development of combustion engines (diesel and petrol)
  • Alternative fuels
  • Catalyst development
  • Hydrogen measurements

Application examples

Automotive industry

  • Hydrogen measurements in combustion engines
  • Gas analysis in fuel cell technology

Steel industry

  • Process control in steel production
  • Monitoring of hazardous exhaust gases in steel production
  • Hydrogen production in a cyclic steelmaking process

Environmental industry

  • Online quantification of tar during biomass gasification

Polymer, tyre and rubber industry

  • Evaporation of inorganic and organic compounds from elastomers

Measurable compounds

  • Permanent gases: H2, O2, N2, CO, CO2
  • Moisture: H2O
  • Noble gases: He, Ne, Ar, Kr, Xe
  • Hydrocarbons: CH4, C6H6, C7H8

Values marked as application-dependent (measuring range, response time, detection limit, gas consumption) depend on the compounds measured, the system configuration and the instrument settings.
