Dymaxion Mass Spectrometer
FEATURES
•No need to match electronics with analyzer head;
offers maximum versatility.
•Zero-drift, electrometer-amplifier technology
provides repeatable data.
•On-board diagnostics provides data integrity.
•Optional on-board analog and digital I/O for
monitoring and control of other sensor inputs.
•RS-232 and RS-485 communication ports for local
and network control.
DESCRIPTION
The Dycor Dymaxion Residual Gas Analyzer (RGA)
offers the latest quadrupole technology to provide
unsurpassed gas analysis monitoring, characterization,
or control for your application. Dymaxion RGAs are
available in a choice of ion source (open, closed,
enclosed) and AMU range (1-100, 1-200, and 1-300) to
accommodate your needs.
Dymaxion analyzer heads and electronics can be
interchanged to provide maximum versatility.
DYCOR SYSTEM 2000 SOFTWARE
Dycor System 2000 software is a 32-bit, multi-threaded program developed to take full advantage of
the capabilities of Windows NT and XP, and is intended for real-time process control.
KEY FEATURES include:
•Extensive systems integration capability with Visual Basic Scripting and DDE and OLE Automation.
•Auto-Tune capabilities to ensure high-quality, repeatable data.
•Real-Time Calculations can be applied to quadrupole or other input data.
•Scripting Capabilities provide the power to automate equipment and process monitoring.
•Spectral Interpretation suggests the gas species that could be contributing to your spectra.
•Customized Displays can be created and saved without programming.
•Optional Analog and Digital I/O for monitoring and control of your process.
•Simulation Mode to facilitate user training and application development.
Dycor System 2000 Upgrades
All Dycor analyzers, M/MA Series, System 1000, and QuadLinks, can be upgraded to operate with Dycor
System 2000 software for Windows 95 through XP. Existing customers can now protect their investment while
maintaining compatibility with the Dymaxion line of RGAs. With a System 2000 upgrade, even the oldest
Dycor analyzer can operate using the latest Windows software.
Dycor Open Ion Source
•Excellent for UHV and leak detection.
•Simple design and construction reduces maintenance
requirements.
•Lowest-cost ionizer option.
•Applications Include:
HV and UHV systems; MBS systems; ion implant
systems; load lock/transfer chambers; wafer preheat
stations.
Dycor Conductance Limited Ion Source
•Ideal for PVD applications.
•Increases signal-to-noise by 100 times over the open
ion source.
•Background interferences are minimized because the
filament does not come in contact with the sample.
•Works best with aprotic (non-hydrogen containing)
gases.
•Applications Include:
PVD, sputter, high purity gas analysis.
Dycor Enclosed Ion Source
•Excellent for CVD and atmospheric pressure sampling
applications.
•Can accommodate a wide range of sample inlet
pressures.
•Less pumping speed required than the conductance
limited source, lowering overall cost.
•Works better than the open and conductance limited
sources in reactive gases.
•No problems with hydrogen-containing gases.
•Applications Include:
CVD, vacuum furnaces, fermentation off-gas,
atmospheric sampling, process stream sampling, etch,
TGA

Use a laptop to control a single analyzer, or use an RS-485 network to control multiple analyzers and analog/digital I/O.
With the System 2000 software, any number of analyzers can be linked for true simultaneous data acquisition and control
from one PC.
