Run fast GC using GC/MS
With faster scan speeds, the Clarus 500 GC/MS opensnew and attractive opportunities in fast GC applications.Extremely narrow chromatographic peaks, previouslyunresolvable with full-scan quadrupole mass spectro-metry, can be easily defined and quantified with theClarus 500 GC/MS (Figure 1). Consider the productivitygains your lab can achieve by applying fast GC/MStechniques, such as in separation of solvent mixtures or semivolatile components.

Figure 1. In fast GC/MS, the Clarus 500 GC/MS resolves peaksthat were previously unresolvable with full scan quadrupolemass spectrometry. The top chromatogram shows resolutionwith slow scan speed, while the lower chromatogramdemonstrates the benefit of increasing the number of scans.
the choice for high performance
Take the lead on GC/MS speed
The Clarus 500 GC/MS is the fastest quadrupole GC/MSavailable, acquiring more spectra (up to 60 scans/second)across a GC peak than any other GC/MS system. Morespectra per peak means more accurate and preciseresults (Figure 2) and better spectral fidelity (Figure 3),resulting in the most complete information and thehighest confidence in analytical data reporting.

Figure 2. Chromatographic signal at fast scan speed (red) compared to slow scan speed (green).
How does fast scan speed improveyour data?
Scan speed is the rate of data acquisition across a
chromatographic peak, measured as scans per second.
Scan speed of a quadrupole mass spectrometer
is critical in ensuring data integrity. Too few scans
across a GC peak lead to poor recorded peak shape,
limiting quantitative accuracy and precision (Figure 2).
A slow scan rate on a fast peak causes spectral
distortion, or “skewing”, reducing spectral fidelity
(Figure 3, top). Faster scanning minimizes the
skewing and gives better overall spectral fidelity
(Figure 3, bottom).
The Clarus 500 GC/MS incorporates fast micro-
processor technology bringing new, high-speed,
state-of-the-art electronics to GC/MS data
processing that maximizes scan speed. Up to 60
scans/second can be achieved, the fastest scan
speed available in quadrupole GC/MS. The result
is the most accurate and precise data ever, easily
beating the generally accepted criteria of at least
8-10 data points per chromatographic peak, for
performance unmatched by other GC/MS systems.

innovative tools bring
productivity to new levels
The Clarus 500 GC/MS features innovative and uniqueproductivity-enhancing tools that help laboratoriesoperate effectively and efficiently.
Selected Ion and Full Ion (SIFI) scanning
The Clarus GC/MS can perform a powerful processcalled Selected Ion and Full Ion (SIFI) scanning in whicha Selected Ion Monitoring (SIM) scan is obtained whilesimultaneously acquiring data in the Full Scan mode.Since SIFI provides the information from both opera-tional modes in one chromatographic run, you receivemore information in less time. With other GC/MS
systems, two or more runs might be required to accom-plish the same task.
With SIFI, labor-intensive pre-concentration and sampleclean-up steps may be reduced or eliminated, saving timeand money on costly solvents. In addition, compoundsdifficult to determine at low levels, such as penta-chlorophenol, can be detected and quantified with greateraccuracy and greater sensitivity. This also reduces thenumber of analyses by combining a wider range ofanalyte responses in a single chromatographic run,improving the throughput of your lab.

What is SIFI scanning?
The Clarus 500 GC/MS can perform a Selected Ion
Monitoring (SIM) scan while simultaneously acquiring
data in the Full Scan mode (Figure 4). Called SIFI
scanning, this unique technique provides more
complete sample information in less time.
The SIM mode increases sensitivity by selectively
scanning for individual masses, while weeding out or
ignoring unwanted or irrelevant masses. This powerful
scan mode focuses all the attention on masses of
interest, without wasting effort and efficiency. By using
SIM, detection limits can be extended down to the
femtogram range. In Full Scan mode, low picogram
levels can be detected, allowing acquisition of library-
searchable spectra over a wide concentration range.
SIFI scanning ensures accurate identification, while
simultaneously providing enhanced quantifiable
sensitivity from the selected ion signal.
SIFI is NOT an extracted chromatogram from a full scan
acquisition. Extracted ion chromatograms offer no
improvement in signal strength for the ions of interest –
only noise rejection from the unwanted masses. SIFI
provides at least an order of magnitude improvement
in detection limits.
SIFI is also a powerful way to troubleshoot unknowns
during routine quantification due to its ability to provide
accurate and complete sample information.
Figure 4. SIFI scanning ensures accurate identification, whilesimultaneously providing enhanced quantifiable sensitivityfrom the selected ion signal.
The software uses Microsoft® Windows® 2000, providing a high level of security, network connectivity andoperating stability. In addition, different levels of useraccess can be defined to ensure data integrity by securingfiles from unauthorized modification. Mass spectral datacan be imported from or exported to industry standardAIA format. A variety of mass spectral libraries forcompound identification, including NIST, Wiley andPfleger/Maurer/Weber, are available.

PreVent modes maximize productivity
PreVent accessory
The PerkinElmer exclusive PreVent productivity tool kitoffers five modes of powerful operation for improvingchromatographic performance, minimizing system down-time and enhancing productivity. Only the PerkinElmerPreVent accessory offers all five modes of operation.
■ MSVent™ mode allows changing of columns withoutcooling and venting the Clarus 500 MS, reducinginstrument downtime, offering a significant timesavings. In addition, MSVent facilitates connection of the vent to a second detector for dual-signalcapability, providing greater flexibility and enhancing productivity.
■ Isolation mode eliminates downtime during routineinjector maintenance and can provide an extra 100analytical hours of productivity per system per year.
When running in Isolation mode, there is no need to interrupt the carrier-gas flow when disassemblingthe Clarus 500 GC injectors for routine maintenance(Figure 7), such as changing the glass liner. Time-consuming oven cool-down and vacuum shutdownperiods are eliminated.
■ Enhanced Large Volume Injection (ELVI) modefacilitates manual injection volumes of up to 150 µLand automatic injection volumes up to 50 µL withoutsolvent reaching the column or the detector, mini-mizing contamination. By eliminating solvents, large volume injection makes time-consuming andexpensive pre-concentration steps unnecessary,significantly decreasing the cost of analysis.

PreVent Accessory Benefits
■ Time-Saver mode prevents unwanted, high-boilingmaterial from reaching the detector, thus shorteninganalysis times and increasing throughput. It facilitatesisothermal chromatography and protects the detectorfrom costly and time-consuming contamination.
PreVent in Time-Saver mode allows changing of theanalytical column without venting the mass spectro-meter, a huge productivity gain for any lab.
■ ProTect™ mode makes many difficult separations ofvolatile components in semivolatile samples possible.In addition, this mode prevents heavy components in the sample from reaching the expensive and veryretentive chromatographic column, saving hours ofcleaning and disassembling procedures. ProTect alsoallows backflushing even during chromatographic runs.
Wide mass range meets complex analytical needs
Because of superior design quality, the Clarus 500 GC/MShas the widest mass range (1.0-1200 Da) available in its class. This gives the capability to analyze highermolecular weight compounds (Figure 8), such as highlyhalogenated compounds and drug derivatives. Even forroutine GC/MS analyses (< 800 Da), the Clarus 500 MSruns far from the quadrupole’s limit, ensuring uncom-promised performance over a wide mass range.

AutoBuild method builder
The unique AutoBuild method builder automaticallysearches spectral libraries for chromatogram peaks andimports them into a quantification method. Names,retention times, spectra and quantification ions of therespective peaks are also imported. AutoBuild savestime building complex, multi-component methods.
rugged design for maximum uptime
The Clarus 500 GC/MS is rugged so it delivers reliability,reduced cost and easy maintenance for maximum uptime.The highly specialized gold component technologyenhances overall instrument stability and reducesmaintenance requirements by minimizing contamination.
The inner ion source is easily accessed from the frontof the instrument without removing the cover or ionoptics from the vacuum manifold. This allows a quicksource changeover in less than 15 minutes and reducesthe risk of contaminating the quadrupole analyzer.Because the Electron Ionization (EI) or ChemicalIonization (CI) sources have no wires, routine cleaningis simple. The filament system is rugged, performingconsistently analysis after analysis, with a self-aligningdesign that makes filament replacement quick and easy.
To maximize spectral quality, the instrument ion sourceand transfer-line temperatures are controlled independ-ently, reducing contamination and protecting thermallylabile compounds from uncontrolled fragmentation.The 350 °C upper temperature limit for the GC transferline and both EI and CI ion sources allow high-temper-ature operation for maximum cleanliness and perform-ance with high-boiling compounds. To simplify
maintenance, cleanable RF-only prefilters are located in front of the quadrupole analyzer.
The Clarus 500 GC/MS improves uptime and through-put of the laboratory with an air-cooled 250 L/secturbomolecular pump that allows up to 5 mL/minhelium carrier gas flow (EI mode). The pump-downtime is minimal (under 3 minutes), qualitative stabilityis reached in under 15 minutes and quantitative stabilityis reached in less than 90 minutes. A water-cooled pumpis optional.
The sealed, long-life photomultiplier detector lowers operating costs by eliminating expensive andcontamination-prone electron multipliers that needperiodic replacement. In the event carrier gas pressuredrops, the unique PerkinElmer Programmable PneumaticControl (PPC) pneumatics safeguard the system fromcolumn damage and ion-source contamination by auto-matically turning off the GC oven and transfer line heating.
Also, you will never need to worry about poweroutages because the Clarus 500 MS vent can beattached to a nitrogen purge gas stream. This prohibitsoxygen from entering the system during venting,minimizing contamination.

flexibility for customized analysis
Depending on your application, the Clarus 500 MS canuse either EI or CI sources in either positive or negativemode (Figure 9). EI produces high-quality classicalspectra that are the basis for compound identificationby library searching. The optional CI mode can be used for any of the following:
• if molecular weight information is needed
• for additional selectivity with complex samples
• when detailed characterization is required
You can run EI mode for rapid screening withoutchanging the CI source, a productivity benefit for your lab.
Further flexibility and creativity with analysis can beachieved through the extensive choice of acquisition-mode options. Full Scan mode is available with Centroidmode and Continuum mode running independently orsimultaneously, while Selected Ion Monitoring modecan run independently or concurrently with the variousFull Scan modes. Overall, there are 32 combinations ofacquisition modes available, giving the greatest amountof information from one sample.
More column choices
Because the Clarus 500 GC/MS allows a carrier-gasflow of up to 5 mL per minute in EI, you have morecolumn choices than with other GC/MS systems.Narrow-, medium- and wide-bore columns can be used, with almost unlimited choice of stationary phase, column diameter and analytical method with the Clarus 500 GC/MS.
