Now your commercial elemental analysis lab comes to you – a valuable resource you can carry on the back of a truck or move easily throughout your inspection department, warehouse, or store.  Fit. Form. Function. The Niton® FXL portable XRF analyzer is engineered for your most challenging XRF-based applications.

  • Exploration & mining  from base metals and Au mining to mineral sands and PGE
  • Industrial minerals – limestone, clay, steel slag, cement, and more
  • Oil & gas exploration – exceptional performance for mud logging, plus gas and oil shale analysis
  • Consumer goods testing  more precise testing for Pb, Cd in toys, jewelry, packaging, and more
  • RoHS compliance  analysis of populated circuit board and consumer electronics for complete confidence
  • Precious metal alloys – ideal tool for refiners and distributors
  • Environmental – test for RCRA metals at less than 10 ppm in soils

Engineered for the Way You Work

The Niton FXL offers our highest performance and lowest levels of detection for up to 40 critical elements.  

  • Constructed from durable Lexan® plastic – dust- and water-resistant to operate flawlessly in harsh environments
  • Compact and weighs less than 30 pounds (14 kg) – easy to transport and operate from the back of a truck, on a portable tripod, or at the loading dock or manufacturing line
  • Advanced batteries support extended continuous operation on a single charge

The Niton FXL field x-ray lab makes elemental analysis easy for everyone.  Open the lid and place your sample into the 9" x 12" x 4. 5" test chamber. Then simply press a button on the bright, 9" color, touch-screen to get accurate results within a few minutes or less.

  •  z-CAL -- a fit-for-purpose calibration and operation methodology for light elemental analysis
  • Thermo Scientific TestAll technology automatically determines the correct analytical testing mode for confident testing
  • Thermo Scientific geometrically optimized drift detector (GOLDD) technology delivers exceptionally sensitive results with remarkable speed
  • XL3t AnalyzerIntegrated CCD camera with small-spot feature – test areas as small as 1 mm and conveniently store sample measurements for later reference
  • X-Y positioning – lets you position the XRF head quickly to the precise spot you want to test
  • Sample spinner – rotates the sample within the chamber during testing, ensuring an overall accurate reading that best characterizes the entire sample
  • Closed-beam design – requires minimal licensing in most countries
