Part of Thermo Fisher Scientific At Line Coating Thickness and Plating BathAnalysis Using Handheld XRF Thermo Scientific Niton XL3t XRF Analyzers Introduction and Overview Skyrocketing costs of metal coating materials such aszinc have driven the need for improved process control.Anything other than the optimum coating thicknessis unacceptable either from a quality control or costcontrol standpoint. The time has come for a fast，nondestructive， and accurate method of measuringcoating thickness and coating weight， and analyzingplating bath solution. Handheld x-ray fluorescence(XRF) offers general metal finishers and others theadvantage of at line testing， eliminating the need to cutsamples and spend valuable time taking the sample to abenchtop analyzer to wait for results. Continuing a Tradition Years of development and attention to customer needshave made Thermo Scientific Niton alloy analyzersthe first choice in XRF technology， bringing lab-quality elemental analysis wherever it is needed in afield-hardened package. Now， in addition to superiorpositive grade identification and composition analysisof alloy/metal coatings and substrates， the Niton°XL3t offers the benefit of our coating thickness/coatingweight measurement technology - providing an“out-of-the-box”nondestructive solution for gauging theeffectiveness of coating and plating systems. Fast and easy-to-use， the Niton XL3t 800 not onlyperforms at line and plating bath solution analysis， butprovides more accurate measurements than non-XRFtechnologies such as eddy current， magnetic induction，and Beta backscatter. You get precise， nondestructivemultilayer coating thickness results in seconds. Testingat the plating line both increases productivity andimproves process efficiency - no more over-coatingor under-coating. What’s more， the Niton XL3t isyour answer to measuring large or irregularly shapedsamples， as well as small-diameter wiring or tubing.Cutting samples for benchtop analysis are a thing ofthe past. From general metal finishers concerned with corrosionresistance and wear resistance， to the automotiveindustry and its needs for passivation coating analysis，to aerospace with the added concerns of corrosionresistance at high temperatures and lubricity， the NitonXL3t has the appropriate application. Typical applications are： · Galvanized zinc over steel · Zinc or zinc alloy over steel · Hard chrome over steel · Electroless nickel over steel · Chrome/nickel/copper over steel， ZamakTM or plastic · DACROMETcoating over steel Rock-Solid Analysis， Grade Identification， and Coating Thickness MeasurementOne of the keys to success of Thermo ScientificNiton analyzers in alloy analysis has long beenthe instruments’fast， stable， accurate， and precisefundamental parameters (FP) based factory calibration.The Niton XL3’s proprietary FP analysis algorithm includes nearly every element of interest in virtually Niton XL3t Benefits At-a-Glance · At line analysis -improved process efficiency and productivity ·Totally nondestructive -sample stays intact on the line； no sample cutting · Accurate data-prevents over-coating， under-coating · Improved precision & composition analysis -identifies non-homogeneous coatings Ease of use -simple to operate， even for nontechnical Users ·Fast， simple reporting and certificate generation Markets Auto / Construction / Fasteners Auto /Plumbing/ Architectural Cutting Tools Aerospace CoatingsPurpose · Corrosion resistance·Wear resistance · Passivation coating ·Decorative· Corrosion resistance · Corrosion resistance at hightemperature ·Wear resistance · Corrosion resistance athigh temperature · Wear resistance ·Lubricity MajorApplications ·Zn/Steel， SS · Zn alloy / Steel， SS ·Ni(P)/ Steel or Plastic · Hard Cr/ Steel ·Organomettalic /Zn / Steel·DACROMET@/Steel ·Cr / Ni / Cu over Plastic ·Cr /Ni/ Cu alloys ·Cr/Ni/Cu / Steel or ZamakIM· Ni only / substrate ·SnCo / Steel ·Au / Ni/ Cu alloys ·W-carbide / Tool steel ·Ti-carbide/ Tool steel ·Ti-nitride / Tool steel ·Cobalt leaching ·Cd/Al ·Ni/Cu/Al ·Mo/Ti ·Cu/Al all types of metal alloys for grade identification andcomposition analysis. Now， it provides a fast， easymeans for testing coating thickness/coating weight andplating bath solution as well， without the requirementfor special empirical calibrations. Yet， providing accurate alloy chemistry is only part ofthe equation. Using our extensive experience with themetals industry，we have incorporated an alloy gradelibrary that simultaneously provides users with thecommon trade name of the alloy on the instrumentdisplay. By incorporating a hybrid approach， whichcombines the SAE Unified Numbering System (UNS)alloy grade specifications with knowledge of the “asproduced”chemistries of these alloys，Niton XL3series analyzers provide unmatched accuracy in gradeidentification. Simply Superior Alloy Analysis We continue to lead the handheld alloy analysis fieldwith technology that responds directly to the needsand requests of the metal production， general metalfinishing， and fabrication industries. The ThermoScientific Niton XL3t 800 Series offers the latest ina series of rugged， dependable tools with improvedergonomics， speed， and performance， while retainingthe point-and-shoot simplicity that has been a hallmarkof our analyzers. By combining advanced electronics and materialstechnology with the most powerful x-ray tubes everused in handheld XRF instruments， the Niton XL3tis in a class by itself. With multiple primary filters foroptimal sample excitation and a helium-purge optionto target light elements from magnesium (12) to sulfur(16)， this analyzer provides the greatest analyticalrange， speed， and precision of any handheld XRFinstrument. The Niton XL3 Series features a high-performancethermoelectrically cooled detector， 80 MHz real-timedigital signal processing， and dual state-of-the-artembedded processors for computation， data storage，communication， and other functions. From the integrated tilting color touch-screen displayto the customizable menus for ease of use， our NitonXL3 Series analyzers are appropriate for use underall environmental conditions， both indoors and out.Couple these features with integrated BluetoothTM，USB， and serial communications， and cumbersomedownload procedures of PDA synchronization becomea thing of the past. What’s more， all Thermo ScientificNiton analyzers use third-generation lithium-ionbatteries， providing the longest usage cycle of anyhandheld XRF analyzer. Service and Support Our Niton XL3 Series instruments have been designedto be the most dependable handheld XRF analyzersever made. From the rugged Lexan@ EXL housingto the precision semiconductor x-ray detector， eachindividual component has been engineered to bedependable as well as easily serviceable.When routineservice is required， we have more than 30 NitonAnalyzers service centers on six continents. Configurations and Accessories Providing the right XRF analysis tool for almost anyorganization's analytical and budgetary requirements，Thermo Scientific Niton analyzers offer a wide range ofoptions in models and accessories. All of our XRF analyzers come with a shielded，waterproof carrying case， shielded belt holster， andPC-compatible Niton Data Transfer (NDTO) softwarefor remote operation， file transfer， data management，and advanced data analysis. Optional items include teststands， hot surface adaptors， and extension handles， aswell as an integrated color CCD camera， which allowsyou to view the specific measurement areas and storethe image together with your analysis data.
