Molecular Beam Sampling

Molecular beam sampling offers the opportunity for detailed measurement of reactive gas species from a wide pressure range. Collisionless transfer of reactive species necessitates careful design of the mass spectrometer sampling system: Extrel are innovators of molecular beam sampling, right up to the present day VeraSpec MB analyzer which uses the unique cross-beam sampling configuration to significantly improves signal-to-noise over axial sampling arrangements.

VeraSpec Molecular Beam Mass Spectrometry System

VeraSpec Molecular Beam Mass Spectrometry System

The Cross Beam Deflector Ionizer rebounds the ionized gas phase species through 90°, separating them from photons, metastables, particulates and molecular beam gases. Filtering out photons and high-energy ions in this way eliminates spurious background signal and preserves the integrity of the quadrupole mass filter, allowing potentially harmful deposits to pass straight through and on to the ultra-high vacuum pumping system.

  • Multi-stage skimmer inlet design
  • Cross beam sampling for highest signal to noise
  • Integrated beam chopper for highest sensitivity
  • Mass ranges from 1-60 to 4-4000 amu
  • Detection of reactive species via threshold ionization
  • Quadrupole deflectors
  • Gas tight housings
