Thermo Fisher Scientific Announces Enhancements to Thermo Scientific Niton XRF GOLDD Analyzers for Low Alloy Steel Markets

New Application Note Highlights XRF as Alternative to OES for Accurate Material Verification in Seconds

(PresseBox) ( BILLERICA, Mass., )
Thermo Fisher Scientific Inc., the world leader in serving science, today published a new application note focusing on the quality control of low alloy steel products using Thermo Scientific Niton handheld XRF analyzers with GOLDD technology. The instruments of choice in nondestructive elemental analysis solutions for metal alloy verification, Thermo Scientific Niton XRF analyzers provide superior accuracy in grade identification and alloy chemistry in seconds. Thermo Fisher Scientific is a pioneer in handheld x-ray fluorescence technology.

Thermo Scientific geometrically optimized large area drift detector (GOLDD(TM) ) technology delivers faster measurement times and lower detection limits - as much as 10-times faster than conventional Si-PIN detectors and up to three-times more precise than conventional smaller silicon drift detectors (SDD). This innovative technology also allows analysis of light elements such as magnesium (Mg), aluminum (Al), silicon (Si), phosphorus (P) and sulfur (S) without helium purge or vacuum assist. When joined with advanced Thermo Scientific Niton analyzer proprietary electronics, new levels of analytical capabilities are realized.

"With improved limits of detection and new additions to our already comprehensive alloy grade library, the Niton XL2 GOLDD and enhanced Niton XL3t GOLDD+ offer primary producers, processors, service centers and end users a reliable alternative to OES for their low alloy steel analysis needs. These instruments help eliminate any guesswork in verifying metal alloys for manufacturing quality assurance as well as incoming material verification, stockroom control and shipment quality control for metal distributors and service centers," said Marc Tremblay, vice president/general manager for Thermo Scientific Niton Analyzers.

Tremblay continued, "We know that the potential for material mix-ups is very real and that the likelihood has grown over the years as more suspect materials are imported from overseas and the use of more recycled components within steel are causing an increase in undesired tramp elements. Our nondestructive analyzers provide a worry-free solution that achieves the high sensitivity required for accurate testing of chromium, nickel and molybdenum - at concentration levels below 0.10 percent."

GOLDD Technology

Whether users choose the performance-leading Niton XL2 GOLDD or the Niton XL3t GOLDD+, the ultimate choice in features plus performance, they will benefit from fast, accurate elemental analysis and positive material identification to ensure manufacturing quality assurance and quality control.

- Niton XL2 GOLDD analyzers have a 45kV, 100 ?A x-ray tube and are lightweight yet ruggedly built to withstand severe environments. Ergonomically designed and featuring daylight readable icons, the Niton XL2 GOLDD incorporates customizable menus for ease of use, multi-language options and a standard analytical range of more than 30 elements from magnesium to uranium. It is the ideal instrument to get rapid results for confident decision-making.

- Niton XL3t GOLDD+ analyzers with their 50kV, 200 ?A x-ray tubes and tilting, color, touch-screen display deliver lab-quality analysis on almost any alloy grade and provide the highest performance and sensitivity for the most demanding applications. For ultra-low Mg analysis, there is a helium purge option. Further, the Niton XL3t GOLDD+ allows users to identify free-machining stainless steels based on sulfur content. Additionally, the integrated Thermo Scientific CamShot CCD camera comes standard for accurate sample positioning and image capture, while the optional Thermo Scientific WeldSpot small-spot feature isolates welds.

A Family of Handheld Thermo Scientific Niton XRF Analyzers

Handheld, award-winning Niton XL2 Series and Niton XL3t Series XRF analyzers are engineered for taking measurements anywhere, anytime, with accurate results available in seconds, saving significant expense compared to traditional laboratory testing. These easy-to-use, nondestructive instruments provide integrated storage of all test results, which are completely tamperproof. Multiple communication options are incorporated, including Bluetooth* wireless and USB communications.

Both analyzers also come standard with Thermo Scientific Niton Data Transfer (NDT(TM) ) software, a suite of data management utilities that allows users to set operator permissions, print certificates of analysis to document results, export data into standard formats (.csv or MS Excel*) or operate the analyzer remotely from a PC. The NDT file format preserves and protects the original data from each sample analysis, ensuring that data is not unintentionally or intentionally compromised.

Thermo Fisher Scientific customers are served through corporate resources and a dedicated network of more than 70 distributors and 30 factory-trained service centers around the world. Thermo Scientific Niton analyzers are available in a range of configurations and with an assortment of optional features and accessories to suit a wide variety of analytical needs.
