Product Specifications

With an enclosed ion source and a
triple-filter quadrupole, the flexible

Benchtop Gas Analysis Mass Spectrometer

Applications• Catalysis research• Thermal analysis• Semiconductor PFC monitoring• Gas purity measurements• Pilot plant gas analysis• Transient kinetic studies• Temperature Programmed Desorption (TPD)• Evolved gas analysis• Air separation plant troubleshooting

Reliable & Compact
The Thermo Scientific ProLab benchtop massspectrometer delivers reliable, cost-effective
analytical performance and offers one of
the smallest footprints for an instrument
in its class. Able to heat the completely
inert sample inlet to +120°C (+248°F),
it achieves fast measurement of evencondensable gases. The enclosed ion
source along with the triple filter ensurea wide dynamic range.
Application-Specific Models
The ProLab benchtop mass spectrometer
meets a wide variety of gas analysis
applications via two optimized configurations.
• The standard ProLab benchtop mass
spectrometer enables cost-effective
performance for demanding applications
such as fast atmospheric pressure
sampling for catalysis, thermal analysis,
and evolved gas studies. This model
can be applied to many atmosphericgas sampling applications.

• The UHP ProLab benchtop mass
spectrometer is for demanding trace
impurity analysis applications.
With a fully bakeable, all-metal
combination capillary inlet, this modelis capable of a 100% to 50 parts
per billion (ppb) measurement range.
Easy to Setup & Service
Two easy-to-change thoriated filaments
extend instrument uptime and minimize
servicing time while the self-aligning source
assembly expedites setup and facilitates
service. Thermo Scientific GasWorks
software also expedites setup and isavailable in a range of languages to fulfill
international requirements. In addition, astandard 12-month comprehensive warranty
and ongoing service and support enablemaximum instrument optimization.

Application: Thermal Analysis (evolved gas analysis)
When high sensitivity is needed to give insight into decomposition
chemistry, the ProLab benchtop mass spectrometer’s Thermal
Analysis-Mass Spectrometry combination provides all theperformance required for materials characterization by evolved gas
analysis. Applications include:• Polymers• Pharmaceuticals• Natural products• Inorganic compounds.

For sample identification, the extensive library enables anunlimited number of compounds to be added. The database canbe searched by mass or compound groups or by automatic library
search by comparison. Stored histograms may be read into theoptional NIST database that contains 75,000 cracking patterns.
For quantitative analysis, GasWorks offers the powerful optionof a complete process quantitation package, allowing full matrix
inversion algorithms, “click on” selection of measured peaks fromthe matrix table, and direct reading of data in ppm or percent.
• Simple, intuitive setup of measurement methods via a clear,easy-to-view graphical user interface• Multi-measurement modes: selective ion scans, spectral scans,and qualitative and quantitative analysis• Instrument and measurement status permanently displayed
and instantly updated• Multi-level user configurable password security system• Comprehensive data analysis and reporting• Modem support enabling remote fault location, tuning,calibration and online application support.

Thermo Scientific GasWorks Software

Thermo Scientific GasWorks Software
Easy-to-use for leak checking yet flexible enough for more advanced
analytical work, Thermo Scientific GasWorks software provides
unrivalled analysis, accuracy and repeatability. Combining click-on
icons and pull-down menu options, it encompasses all of theanalytical measurement modes required for routine or researchanalyses, including analog scans and multi-decade histogram scans.
Changes to the setup or display can be made in mid-analysis without
interrupting data collection, storage or critical alarm settings.

Thermo Scientific ProLab Benchtop Mass SpectrometerFeatures & Benefits• Enclosed ion source results in high sensitivity, lowbackgrounds, better stability and a longer source lifetime• Detachable ion source allows for easy cleaning
and filament change• Triple filter option ensures contamination resistanceand precision• Completely inert sample inlet can be heated to+120°C (+248°F) for measurement of condensable gases• Powerful Thermo Scientific GasWorks software provides
qualitative and optional quantitative determinations,
including full-matrix inversion analysis• Small footprint, benchtop system saves valuable floor
and bench space• Under-mount multi-stream inlet available• Multi-level security and user configurable alarms• User installable, no specialist knowledge or tools
required, instant analysis

Tailored Sample Introduction Systems
To fulfill the need for analysis of multiple samples with rapid sample
throughput, the ProLab benchtop mass spectrometer’s inlet options
cover atmospheric and low vacuum sampling devices as wellas corrosive and condensable gases.
• The standard capillary inlet and bypass for atmospheric pressure
sampling offers durability and rapid response (~500 msec).
The direct coupling of the inlet to the source ensures accurate
sample transport and no mass fractionation effects.
• The leak valve inlet is for variable sampling pressures from
10 bar to 10-3 mbar.
• The thermal analysis capillary inlet and bypass for atmosphericpressure sampling offers a ceramic probe for connection tothermobalances, etc.
• The UHP, all-metal atmospheric inlet for atmospheric sampling of
UHP gases is available with a temperature controlled heating option.
• The multi-way sample inlet with a direct connection to theProLab benchtop mass spectrometer via capillary is suitable
for six sample lines and six calibration lines, all controlled
by GasWorks software.
• The dimethyl silicone membrane inlet gives enhanced
VOC sensitivity, typically from 5 ppb to 1000 ppm.
