Browse Button Retrieves a previously saved tune file. Navigate tothe location of the file and select it.

Save Button Saves current tune parameters to a tune file (de-fault extension .tun). These settings can be im-ported later using the Tune File text box or usingthe Browse button.

Make Default Sets the current tune file as the one to use in allmodes that use this quadrupole.


Emission CurrentElectron emission current used to ionize molecules in the ion source.The filament power will be adjusted until the actual electron currentequals this value. 1E-3 amps (1 ma.) is the best choice for mediumpressure work. If this value is changed, the sensitivity of the analyzerwill change and it should be recalibrated.Range: 1E-4 to 1E-2 amps (.1 to 10 ma.)

Electron EnergyEnergy of the ionizing electrons in the ion source. It is measured inelectron-volts or the difference in potential between the filament andthe source grid. Most data available on the ionization efficiencies andcracking patterns of various molecules are taken at -70 volts and rarelywill this parameter need to be changed. During a degas operation thisvoltage will increase to -250 volts until the degas is complete.Range: -150 to -30 volts

Focus VoltageNormally set to -20 volts. A slight increase in sensitivity can be ob-tained by adjusting this voltage but severe mass discrimination canoccur at extreme limits.Range: -200 to +10 volts

Repeller Voltage (Non-CIS Head)This parameter sets the voltage on the repeller grid that surrounds theionizer. It is normally set to a few volts above the Electron EnergyParameter so the electrons are contained within the ionizer andshould never be set positive with respect to the filament. This param-eter is normally set to minus 72 volts when the Electron EnergyParameter is set to -70 volts.Range: -200 to +10 volts

FrequencyRF frequency applied to the mass filter. Should be adjusted so the RFTune Value is minimized within its typical operating range. Frequencyparameter should be adjusted up or down until the RF Tune Value isminimized. Normally use the Auto Calibration.Range: 1.000 to 3.000 MHz

Cal Low Mass*Normally keep this value set to 1. At the low mass, the low position,low sensitivity and low resolution calibration values will be used.Range: 1 to 100

Cal High Mass*Set to 100 or 200 depending on whether the device has a 100- or 200-AMU range. At the high mass, the high position, high sensitivity andhigh resolution calibration values will be used.Range: 1 to 200


Low PositionUsed to adjust the peak positions at the low end of the scan range sothe peaks correspond to their associated AMU values. Increasing thisvalue shifts the peaks to the right. Decreasing this value shifts peaksto the left.Range: -10 to 10

High PositionUsed to adjust the peak positions at the high end of the scan range sothe peaks correspond to their associated AMU values. Increasing thisvalue shifts the peaks to the right. Decreasing this value shifts peaksto the left.Range: -10 to 10

Low ResolutionUsed to adjust resolution of the peaks at the low end of the scanrange. Normally adjusted for a 10% valley between the peaks ofadjacent masses.Range: 50 to 4100

High ResolutionUsed to adjust resolution of the peaks at the intermediate and higherend of the scan range. Normally adjusted for a 10% valley betweenthe peaks of adjacent masses.Range: 50 to 4100

Low SensitivityThe ion energy in electron-volts that the ions entering the mass filterwill have for the low masses. If the energy is increased, the sensitivitywill increase but the resolution may decrease. Standard setting (6.00)provides a partial compensation for the decrease in sensitivity at highmasses while keeping the best possible resolution.

Range: 3.00 to 10.00

High SensitivityThe ion energy in electron-volts that the ions entering the mass filterwill have for the high masses. If the energy is increased, the sensitivitywill increase but the resolution may decrease. Standard setting (7.00for 100-AMU units and 8.00 for 200-AMU units) provides a partialcompensation for the decrease in sensitivity at high masses whilekeeping the best possible resolution.Range: 3.00 to 10.00


Amplifier CalibrationWith Emission Current set at 1.0E-3, an AMP CAL of 5.0E-3 allows thepartial pressure readings to be approximated in torr. This is a gainparameter by which each current reading is multiplied. When Ampli-fier Calibration is set to one, the partial pressure readings are in amps.Range: 1.0E-10 to 1.0E10

Total SensitivityThis calibration factor can be set between 0.1 and 999.9. It can beadjusted so that the total pressure reading agrees with an ion gaugereading. The number is a simple multiple of the measured totalcurrent to the Faraday Cup when reading total pressure.Range: .1 to 999.9

Multiplier VoltageApplies only if you have a multiplier-type analyzer (not a FaradayCup). This is the multiplier voltage placed on the multiplier. A typicalvalue is -1000 volts.Range: 0 to -2000 volts


Viewing Devices

1. Select View/Devices & Log or click on the icon. A log is dis-played showing the active device and its status.

• Mass (all modes other than Analog and Bar)Define the specific mass number to track. You can also select a gas fromthe list to the right of the mass number.

The gas list is stored in a text file called �gas.txt.� It can be custom-ized to your application.

!NOTE

!NOTE

Scanning Data | 5-3

• Samples per AMU (Analog Mode only)Number of samples the system will take for each selected AMU. Thehigher the samples-per-AMU, the better the resolution. In Analog mode,more samples per AMU allow you to resolve separate peaks more eas-ily. You can set this value between 4 and 15.

• Dwell TimeTime the system allots for each sample. Dwell time determines scan-ning speed and background noise. The more time allotted for eachsample, the higher the signal-to-noise ratio. Very low pressures requirea slower scan speed.

• Auto ZeroChecked - Allows subtraction of the amplifier drift effects from all read-ings.

There will be a speed penalty if Autozero is turned on because the systemtakes two readings for each reading displayed.

Automatic Calibration | 11-1

AUTOMATIC CALIBRATION

The Automatic Calibration function adjusts and optimizes RF frequency,mass resolution, and mass position. You can also check to see if the currenttune parameters are within tolerance. Ideally, you should use a calibrationgas with peaks at the low and high ends of the mass range. However, themass spectrometer can be calibrated using residual air.

Click on Control on the menu bar and select Auto Calibration from thedrop-down menu to bring up the Automatic Calibration dialog box.

Device List Box

Allows you to select the quadrupole head on which to perform theautomatic calibration.

Figure 11-1.Automatic Calibrationdialog box.


Properties Button

Takes you to the Device Properties dialog box where you can view orchange properties for the device selected from the Device list box.

Mass Text Box

Defines the low and high mass of the calibration gases. The left text boxcorresponds to the low mass. Ideally a calibration gas as close as pos-sible to 1 should be used. For the high mass, use a calibration gas that isclose to the top of the operating range. For example, if operating up to100 AMU, use a calibration gas in the 90s AMU range.

WidthText Box

Allows you to set the resolution by specifying the width in AMU thateach peak should have for both the low and high mass calibration gas.Width is measured at 25% of the total peak height. If, for example, youset the peak width at .8, you are telling the system that at 25% peakheight it should be .8 AMU wide. Decreasing the width improves theresolution but lowers the sensitivity. To get better sensitivity, increasethe width. If the peak width is set too wide, you may start to lose theability to distinguish between adjacent peaks.

RF Tune Box

Displays the RF Tune value in the box to the right of the label. Thesquare to the left appears green if the value is within specifications. Itappears red if out of specification.

Resolution Box

The square to the left appears green if the value is within specificationsand red if out of specification. For example, if the width is set to .8, theindicator will appear green if the AMU width is sufficiently close to .8AMU at 25% peak height.


Position Box

Tells you whether selected masses (from high and low calibration gases)are properly positioned. In other words, you want to ensure that thepeak for 18 appears at 18 and not at 18.5 or 17.5. It allows you to shiftthe peaks left or right. The square to the left appears green if the valueis within specification or red if out of specification.

Check Button

Checks the RF Tune, resolution and position but does not attempt tochange them. The settings appear on the display window above thePosition and Width text boxes.

Start Button

Starts the automatic calibration, optimizing RF Tune, resolution andposition. When complete, the display windows should show data thatis properly positioned, resolved and with proper sensitivity.

Resolving an RF Tune Error

Analyzer electronics must be RF-tuned to match the quadrupole analyzerhead. New analyzers are tuned at the factory. If you see the message “RFTune Failure” in the Devices & Log status box, it may be caused by one ofthe following.

• The electronics were removed from onehead and installed on another.

• Circuit boards were replaced during a repair.

• There is an electronics circuit failure.

• The analyzer head is damaged.

Setting the RF Tune

The RF Tune is set using the Auto Calibration dialog box in the System 2000software.

1. On the Control menu, click Auto Calibration.

If you have more than one device, make sure you have selected thecorrect device to initialize.

2. On the Automatic Calibration dialog box, click the Start button. Whenthe RF Tune box turns green, click the Stop button.

If the RF Tune box turns red, there is a circuit failure, or the analyzerhead is damaged. Pleas contact AMETEK for assistance.

3. Click OK to close the Auto Calibration dialog box.

4. On the Mode menu, click Analog. Right-click on the screen and clickon Display. In the Display mass range boxes, enter “1” for Low and “50for High. Allow the analyzer to warm up for approximately an hour.

5. At the end of an hour, observe the positions of the peaks on the analogscreen to determine how much coarse tuning is needed before you canperform an auto calibration. For example, if you are sampling air, lookat peaks at mass/charge 14 and 40.

!NOTE

!NOTE


Click on the left mouse button and hold it down to move the cursoranywhere on the mass scale to see the location on the mass scale.

If the peaks of interest are off by more than 0.5 AMU, you must manuallyadjust the mass position. If the peaks are off by less than 0.5 AMU, go toStep 2 of “Coarse Adjustment of Mass Position.” For example, if the maxi-mum of peak 14 appears at 13.6 and peak 40 appears at 39.8, no adjustmentis necessary. However, if peak 14 reads 13.1 and peak 40 reads 39.03, youneed to perform coarse adjustment.

Coarse Adjustment of Mass Position

On the Edit menu, click Device Properties and then click the Tune Param-eters tab.

1. While looking at the scan, note the positions of the peaks to determinein which direction you need to adjust the mass position.

If the peaks shift to the right (higher)Decrease the numbers in the tune file at “low position” and/or “highposition.”

If the peaks shift to the left (lower)Increase the numbers in the tune file at “low position” and/or “highposition.”

Start out by changing the numbers by approximately 1 unit (e.g., from3.20 to 2.20, or from -1.50 to -2.50). After you change the numbers, clickOK and observe the next analog spectrum to see how the peaks haveshifted. If the resulting peak positions are acceptable, go to Step 2. Ifthe peak positions are still off by more than 0.5 AMU, repeat Step 1.

2. On the Control menu, click Auto Calibration. Make sure you have thecorrect device selected.

Click the Start button and observe the boxes for RF Tune, Resolutionand Position. When all three status lights have turned green, click OK.

Your analyzer should now be properly calibrated.
