High Mass Range Analysis

Scientific research involving Molecular ClustersIon Clusters and Nanostructures rely on Quadrupole Mass Filters that are capable of transmitting ions of high molecular weight or m/z ratios. Extrel’s MAX Systems are designed specifically for the researcher’s needs. We offer quadrupole, hexapole, octupole and conical octupole ion guides for almost any experimental configuration.

Individual components are available for systems that are user-designed and assembled. Custom engineering is available for Extrel system-users, including those who are using multiple chambers and differential pumping. Extrel also offers Electron Ionization (EI) and Atmospheric Pressure Ionization (API) ion sources.

Multiple chamber/differentially pumped systems can be designed for on-axis as well as for off-axis operation. Off-axis systems are designed to optimize signal to noise by eliminating neutral interference at the detector. This is done by bending ions which allows neutrals to pass directly through the bender.

Extrel MAX Products include:

  • Cross Beam Deflector Ionizer
  • Hexapole Collision Cell
  • MAX Flange Mounted MS Systems
  • Quadrupole, Hexapole, Octupole and Conical Octupole Ion Guides
  • 440 kHz RF/DC Power Supply
  • Standard and custom designed differentially pumped systems
  • Standard and custom length Einzel Stack focusing lenses
