Thermo Fisher Scientific has published an application note focusing on the quality control of low-alloy steel products using Thermo Scientific Niton handheld XRF analysers with GOLDD technology.
The instruments of choice in nondestructive elemental analysis solutions for metal alloy verification, Thermo Scientific Niton XRF analysers provide high accuracy in grade identification and alloy chemistry in seconds.
Thermo Scientific geometrically optimised large-area drift-detector (GOLDD) 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), according to the company.
This technology also allows analysis of light elements such as magnesium (Mg), aluminum (Al), silicon (Si), phosphorus (P) and sulphur (S) without helium purge or vacuum assist.
When joined with advanced Thermo Scientific Niton analyser proprietary electronics, new levels of analytical capabilities are realised.
Whether users choose the Niton XL2 GOLDD or the Niton XL3t GOLDD+, they will benefit from fast, accurate elemental analysis and positive material identification to ensure manufacturing quality assurance and quality control.
Niton XL2 GOLDD analysers have a 45kV, 100uA 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 customisable menus for ease of use, multi-language options and a standard analytical range of more than 30 elements from magnesium to uranium.
Niton XL3t GOLDD+ analysers with their 50kV, 200uA X-ray tubes and tilting colour touch-screen display deliver lab-quality analysis on almost any alloy grade and provide high performance and sensitivity for the most demanding applications.
For ultra-low Mg analysis, there is a helium-purge option.
The Niton XL3t GOLDD+ allows users to identify free-machining stainless steels based on sulphur 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.
Handheld Niton XL2 Series and Niton XL3t Series XRF analysers are engineered for taking measurements anywhere, anytime, with accurate results available in seconds.
These 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 analysers also come standard with Thermo Scientific Niton Data Transfer (NDT) 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 analyser 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.
