Introduction:YourNITONXRFAnalyzerTHE NITON XLP XRF ANALYZER OVERVIEW

The NITON XLp Analyzer is a single unit, hand held, high perfor-mance portable x-ray fluorescence (XRF) elemental analyzer.

THE CONTROL PANEL

The control panel is located on the instruments top housing, directly below the LCD touch screen (see Figure I-2). The control panel consists of a 4 way touch pad and two control buttons, one on each side. Using either the control panel or the touch screen (with or without the NITON standard touch screen stylus accessory, that clips in the XLp battery pack) you may navigate through all of the instruments screens and menus. You can control the movement of the screen cursor by pressing the four way control pad in one of four directions to highlight each of the menu options. The enter but-ton on the right side of the four way touch pad is used to select highlighted menu options. The on/off/escape button both controls the power to the instrument and serves as an "escape" button. When the on/off/escape button is pushed and immediately released, it

Chapter1:RadiationSafetyChapter 1 RADIATION SAFETY

The NITON XLp Analyzer was designed so that virtually no mea-surable radiation external to any part of the instrument can escape when the shutter is closed. When the instrument is used in accor-dance with it's instructions, it is completely safe, that is, there is minimal radiation exposure, even with the shutter open.

NITON XLp 300A/700A Series Analyzers contain a sealed 109Cd radioactive isotope source. The source is designed to remain secure even under extreme conditions, so that even if the instrument is bro-ken, crushed or burned, there should be no leakage of radioactive material.

During manufacturing, each sealed isotope source is locked in place in a solid tungsten alloy source holder. The source is completely secure in its housing because the aperture at the closure end of the housing is smaller than the source and is completely sealed. The source assembly is secured in the instruments case, which is fitted with tamper-proof screws.

Your exposure to radiation is determined by three factors: time, dis-tance, and shielding. Human exposure to radiation is typically mea-sured in rems, or in one-thousandths of a rem, called millirems (mrem).

For a given source of radiation, three factors will determine the radiation dosage you receive from the source:

1. Duration of ExposureThe longer you are exposed to a source of radiation the more radiation strikes your body and the greater the dose you receive. Dosage increases in direct proportion to length of exposure.

2. Distance from The SourceThe closer you are to a source of radiation, the more radiation strikes you. The dosage increases in inverse-squared relation to your distance from the source of radiation. For example, the radiation dose one inch from a source is nine times greater than NITONXLp300SeriesLeadinPaintAnalyzerUsersGuideChapter11

Chapter1:RadiationSafetythe dose three inches from the source, and 144 times greater than the dose one foot (12 inches) from the source. For another example, the radiation dose one meter from the source of radia-tion is 100 times lower than the dose at 10 cm from the source of radiation. Keep your hand and all body parts away from the front end of the instrument when the shutter is open to minimize your exposure.

3. ShieldingYour instrument emits virtually no radiation with the shutter closed because the 109Cd source is thoroughly shielded in every direction. This shielding absorbs nearly all of the radiation produced by the source except when the shutter is open during testing. With the shutter open, the instrument emits a conical primary beam (see Fig-ure 1.1) of radiation out the front of the device. This beam is mostly absorbed by sample in a typical measurement. Without a sample, the in-beam dose rate is approximately 315 mrem at a 5cm distance distance from the front of the device.

Note: Wearing a dosimeter badge does not protect you against radia-tion exposure. A dosimeter badge measures your exposure.

Note: Pregnant workers may want to take special precautions to reduce their exposure to radiation. Qualified scientists have recom-mended that the radiation dose to pregnant women should not exceed a total of 500 mrem/gestation period. See U.S. NRC Regulatory Guide 8.13 "Instruction Concerning Prenatal Radiation Exposure".

Chapter1:RadiationSafetyHOW TO USE YOUR NITON XLp

The NITON XLp was designed to be as safe as possible. However, we strongly recommend that you follow these precautions to insure your safety and the safety of those around you.

WARNING!

Always be aware of the location of your instruments radioac-tive sources and the direction of their beam of X-rays. The loca-tion of the sources is at the front end of the instrument.

Open the shutter only to do a test. The shutter can only be opened after the user has logged on to the instrument using the password.

During testing, a strong beam of radiation is continuously emitted through the kapton window at the front of the instrument (see Fig-ure 1-1). There will be some radiation at the front and top-front of the instrument. There is negligible radiation at the handle of the instrument.

Caution

Your XLp analyzer must have the correct time and date set in order to test samples correctly using the 109Cd radioisotope source. Please make sure that the time and date are set correctly before testing.

WARNING!

It is important that the date and time information displayed on the Date and Time screen is correct. If either the date or time is incorrect, the information stored with your readings will be incorrect. In addition, an incorrect date prevents the instrument from properly compensating for normal source decay - causing erroneous analysis results for instruments equipped with 109Cd. This information must be correct before proceeding with testing.

The instrument will automatically return you to the Main Menu when the entry is complete.

Select the Current Baud Rate icon to change the communications rate for the RS-232 port. Selecting the Current Baud Rate icon will toggle the communications rate between 115 kbaud and 38 kbaud.

USING PB PAINT MODE

Your NITON XLp 300A/700A Series Lead-in-Paint Analyzer is designed to detect and quantify the amount of lead present in painted surfaces. Your analyzer also tracks important information about your site readings using the integrated bar-code scanner or the analyzers control panel.

Both Paint Modes can be used interchangeably to measure lead concentrations in paint in mg/cm2. In all paint modes, NITON ana-lyzers simultaneously measure and analyze both K-shell and L-shell lead x-rays to determine:

1. The numerical value of the lead in mg/cm2 present in the sam-ple;

2. The 95% confidence interval; and 3. Whether the sample has a lead concentration that is greater-

than-or-equal-to ("Positive") or less-than ("Negative") the lead Action-level (in mg/cm2) that has been entered.

Note: In all paint testing modes, if a test is stopped before a "Positive" or "Negative" determination has been made, you will get a "Null" test result.NITONXLp300SeriesLeadinPaintAnalyzerUsersGuideChapter41

When one of these Pb Paint Mode Menu icons is selected, the function specific sub-menu appropriate to that icon will be displayed.

The Standard Mode icon allows you to select the Lead-in-Paint Standard Mode. In Standard Mode, the instrument reads until a 95% confident reading of "Positive" or "Negative" versus the Action-level is achieved. Then the instrument displays either Posi-tive or Negative, and the Result in mg/cm2. In Standard Mode, testing times will vary somewhat from sample to sample. The instrument will measure only until a 95% confident reading of "Positive" or "Negative" (versus the Action-level you have set) has been attained. Press the down section on the 4-way touchpad to see the Depth Index.

The Depth Index is a numerical value indicating the amount of non-leaded paint covering the lead (if any) detected by the analyzer.


Chapter4:PbPaintModeA Depth Index of less than 1.5 indicates a reading very near the surface. A Depth Index between 1.6 and 4.0 indicates a moderate depth, while a Depth Index of greater than 4.0 indicates a deeply buried reading.

The K+L Mode icon allows you to select the Lead-in-Paint K+L Mode. In K & L Mode, the instrument displays the complete test information continuously, from the beginning of each reading, including the K-shell reading with two-sigma confidence interval, the L-shell reading with two-sigma confidence interval, the combined reading (Pb) with two-sigma confidence interval, and the Depth Index. With each reading, a Null result is displayed until a Positive or Negative result is determined. In K & L Mode, you may continue readings indefinitely after a "Positive" or "Negative" result is obtained, until you have attained a desired measurement time or degree of precision.

Trigger-and-Proximity-Sensor method. With the Trigger-and-Proximity-Sensor method, you must place the measurement window against the surface to be analyzed to engage the prox-imity sensor on the front of the instrument, then pull the trigger for sample analysis to be initiated.

Momentary-Trigger-Touch-and-Proximity-Sensor method. With the Momentary-Trigger-Touch-and-Proximity-Sensor method, you must place the measurement window against the surface to be analyzed to engage the proximity sensor on the front of the instrument, then pull the trigger.

The trigger may be released and the reading will continue until you release the proximity button, or other criteria (such as Max Time) are reached. This is the primary mode of operation for the XLi XLp 300A/700A Series Lead-in-Paint Analyzer in the USA.

Trigger-and-Interlock method. With the Trigger-and-Interlock method, you need to place the measurement window close to the surface to be analyzed, press and keep pressing the interlock button at the rear of the instrument with your free hand, then pull the trigger for sample analysis to be initiated.

Trigger-Interlock-and-Proximity-Sensor method. With the Trig-ger-Interlock-and-Proximity-Sensor method, you must place the measurement window against the surface to be analyzed to engage the proximity sensor on the front of the instrument, press and keep pressing the interlock button at the rear of the instrument with your free hand, then pull the trigger for sample analysis to be initiated.

After your NITON XLp analyzer is calibrated and your Data Entry is complete, initiate a sample reading using the appropriate method. If you attempt to initiate a sample reading using a different method, the analyzer will inform you that one or more of the preconditions need to be met in order for sample analysis to begin.

Chapter4:PbPaintMode WARNING!

The Proximity Button must remain depressed for the duration of the reading in Standard Mode or K+L Mode. If the Proxim-ity Button is released, the three LED lights will stop blinking, the shutter will close, and the measurement will end. The flash-ing of the LED lights is not synchronized to optimize power consumption.

To end a K+L Mode test, simply release the Proximity Button.

WARNING!

The three LED warning lights are designed to blink only dur-ing instrument calibration (See Chapter 2 page 16) or during a measurement, where the shutter is open and the preconditions for operation are in effect. If the LED lights blink at any other time, disconnect the battery pack immediately, place the instru-ment in its shielded holster, place the holster in the shielded car-rying case, and call Thermo Electron Corporations Service Department in the United States, toll free, at (800) 875-1578, or outside the United States, at +1-978-670-7460, or your local Authorized NITON Service Center.

Your NITON Analyzer will display the Results Screen throughout the duration of each reading, The Results Screen is updated regu-larly throughout the reading. When the reading is complete, a final screen update will appear, and your NITON analyzer will display the final results of the measurement which has just been completed.

Chapter4:PbPaintModeSTANDARD MODE RESULTS SCREEN

Before the analyzer has reached a determination, the result will be shown as Null. Your analyzer will beep twice when a result is reached then terminate the reading. The display will change from Null to show the result, either Positive for lead detected above the action level, or Negative for no lead or lead below the action level. It will also display the amount of lead detected in mg/cm2.

If you want to see the Depth Index, press the down section on the 4-way touchpad.

The Depth Index is a numerical value indicating the amount of non-leaded paint covering the lead (if any) detected by the analyzer. A Depth Index of less than 1.5 indicates a reading very near the surface. A Depth Index between 1.6 and 4.0 indicates a moderate depth, while a Depth Index of greater than 4.0 indicates a deeply buried reading.

Chapter4:PbPaintModeK+L MODE RESULTS SCREEN

The K+L Mode Results Screen will show the basic display indi-cated in Figure 4-3B throughout the reading. Your analyzer will beep twice to indicate it has reached a conclusion, and the Result field will change from Null to Positive or Negative, but the reading will continue for as long as you continue to contact the Proximity Sensor.

The K+L Results Screen shows the reading results and error for both K and L-shell readings. The Lead Detected in mg/cm2 total field is the result of the instrument softwares determination as to which reading, K or L-shell, best represents the true condition.

The Depth Index is a numerical value indicating the amount of non-leaded paint covering the lead (if any) detected by the analyzer. A Depth Index of less than 1.5 indicates a reading very near the surface. A Depth Index between 1.6 and 4.0 indicates a moderate depth, while a Depth Index of greater than 4.0 indicates a deeply buried reading.

SMincoTHE DATA ENTRY SCREENS

The Data Entry Screen and subsidiary sub-screens allow you to set the values for various parameters tracked by the system along with the actual analysis results. These parameters all describe the particular test target to be analyzed. The location of the target in the site, the type of target, the surface and substrate, the condition of the surface, and the inspector performing the test are some of the parameters tracked by the analyzer.

Navigating the Data Entry Screen

Above is a sample of the Data Entry Screen. To navigate through the Data Entry Screen and select your parameter settings, you can use the touch screen display or 4-way touch pad and control panel buttons.
