Extrel is widely respected for the quality of mass spectrometer systems that are available to the world's top research scientists. In response to increasing requests for complete turn-key systems built around their well-respected quadrupole mass spectrometer technology, Extrel has introduced the VeraSpec™ line of research grade mass spectrometer systems. The Extrel VeraSpec™ MB2 and VeraSpec™ MB3 molecular beam mass spectrometer systems are compact systems, which utilize a 2- or 3-stage skimmer inlet with interstage optics for the analysis of gases and ions, including from plasma, from 2 mTorr...

Extrel VeraSpec™ MB systems feature our crossbeam deflector ionizer (below) and can be customized with a chopper and lock-in amplifier (left) and high pressure plasma diagnostics Enhanced Chemical Vapor Deposition (PECVD) Pressure Chemical Vapor Deposition (LPCVD) MB2 and MB3 Cross Beam Deflector Ionizer deflects ions 90° off-axis, separating ions from common background noise sources such as photons, metastables, particulates, and molecular beam gases.  Analog System Highlights: VeraSpec™ MB2 ion/electron attachment option gating option (beamchopper and lock-in amplifier) Automation™ data system...

Molecular Beam Sampling for Gas Analysis The power of mass spectrometry as an analytical technique is well known, and mass spectrometers have been widely used for residual gas analysis. However, for samples that are not a residual gas contained in the mass spectrometer vacuum chamber, an effective sampling arrangement must be used. Among the possibilities, molecular beam sampling is an effective way to introduce neutral gas or pre-formed ion samples over a wide range of sample conditions. Three molecular beam systems are available to suit the broadest application requirements: the VeraSpec™ MB2,...

The heart of a VeraSpec™ MB system is Extrel's MAX Series flange mounted quadrupole mass spectrometer system.The MAX system consists of a mass spectrometer probe, including an electron impact ionizer, tri-filter quadrupole mass filter, and electron multiplier detector, the MAX-CS mass spectrometer Control System, and MAX-QCi integrated Quadrupole Control system. The 19 mm tri-filter quadrupole, with precision machined rod set, RF-only pre- and post-filter stages, and stabilizing rods, combine with the CS control system and the QCi quadrupole control RF supply to deliver excellent transmission,...

The Extrel VeraSpec™ MBx quadrupole mass spectrometer system is a 3-stage discreetly pumped, gas analysis system designed for sampling reactive and condensable gases. The MBx is designed with a heated inlet, easily-changed first aperture and skimmer, and an isolation gate valve, to allow inlet maintenance for applications, which have challenging sample conditions, such as pyrolysis. The carefully-engineered inlet provides a supersonic expansion of the sample into the vacuum to maintain sample integrity ensuring accurate analysis of analytes before they react or decompose. The System Highlights...

Engineering and Application Support System Highlights: Extrel recognizes that every analytical requirement for a research project has its own unique demands. As with all of the VeraSpec™ research grade systems, Extrel's salespeople, engineers, and application scientists will work with you to understand your specific configuration needs for the VeraSpec™ MB systems. A variety of aperture sizes and pumping options are available, and custom variations based on the VeraSpec™ MB base systems create a flexible and powerful approach to providing a molecular beam quadrupole mass spectrometer for your...
