Thermo Scientific Featured Product

Niton XL3p Analyzer Handheld Analyzer

The handheld Thermo Scientific Niton XL3p x-ray fluorescence (XRF) analyzer combines it’s patented Infiniton™ radioisotope source with advanced electronics and materials technology. The result directly benefits users with the fastest measurement times, improved detection limits, and the most reliable, easy to use tools for elemental analysis in the industry. From the integrated tilting color touch-screen display to the customizable menus for ease of use, the lightweight XL3p delivers heavyweight performance with a set of features engineered to improve productivity and profitability.

In 1999, Thermo Scientific pioneered the introduction of handheld, lab-quality, isotope-based XRF analyzers. With an improved version of it’s Infiniton source and the latest in advanced analog and digital electronics design, they combine our industry-leading expertise in portable XRF analysis and applications development with the direct feedback from customers to provide the marketplace with the both the lightest weight and most ruggedly constructed handheld XRF analyzers worldwide. Thermo Scientific is now the only manufacturer to offer both isotope and x-ray tube based XRF analyzers, helping customers select the best excitation technology for their application and their local radiation control regulations.

The XL3t XRF Analyzer

The Thermo Scientific Niton XL3t handheld x-ray fluorescence (XRF) analyzer with GOLDD technology joins advanced, proprietary electronics with the most versatile x-ray tubes and one of the largest area silicon drift detectors commercially available to take your analytical capabilities to a whole new level. GOLDD technology stands for Geometrically Optimized Large Drift Detector, and it is the cornerstone of the most significant improvement to XRF analysis since the introduction of the Niton XL3t in 2007, yielding up to a 10x performance gain over this award-winning analyzer.

GOLDD Technology: The most versatile XRF analyzer on the market

This performance gain is a function of several factors, including Geometric Advantage, Optimized Excitation, and a Large Drift Detector. Fundamentally, silicon drift detectors have the capacity to process more counting events than Si-PIN detectors traditionally used in handheld XRF analyzers. Unless the instrument has been engineered to take advantage of these counting events, it squanders the opportunity to provide dramatically improved analytical performance.

  • Excitation intensity is exponentially proportional to the excitation voltage. Increasing the excitation voltage by 25% has a much greater effect than increasing the tube current by a similar amount
  • To take advantage of a detector with a higher count rate, more fluorescent x-rays must be produced by the sample
  • With a larger silicon drift detector, the Niton XL3t collects up to 2.5x more signal
