MAX Flange Mounted Systems

The MAX systems are complete, ready-to-run flange mounted Quadrupole Mass Spectrometers. Each comes with control electronics and data acquisition software, ready to install on a user-supplied Windows 2000 or XP PC.

The base MAX system consists of an axial molecular beam ionizer with flat aperture plate, mesh shield and tungsten filaments, Tri-filter quadrupole mass filter with RF only pre- and post-filters* and entrance and exit lenses, multiplier housing with positive ion only counting multiplier, pulse counting or analog preamplifier, six or eight inch UHV conflat flange, 150-QC RF Power Supply and associated raw supplies, Merlin Automation Data System control electronics, and all suitable cables and vacuum wiring.

MAX systems are designed with the flexibility to meet the requirements of specific applications and to be modified and upgraded to adapt to future requirements. Please contact an Extrel Representative for a complete list of MAX system options.

For detailed information about the MAX Systems ask for Product Note SP_0103 "MAX Add-on Quadrupole Mass Spectrometers".

     * The MAX 500b uses a Mass Filter without RF only Pre- and Post- Filters.
