Upgrades to GOLDD Technology Help Deliver Rapid, On-site Geochemical Analysis

BILLERICA, Mass. – Thermo Fisher Scientific Inc., the world leader in serving science, will demonstrate the latest members of its family of Thermo Scientific Niton handheld XRF analyzers, the new Thermo Scientific Niton XL2 GOLDD Series and the enhanced Thermo Scientific Niton XL3t GOLDD+ Series, at Mining Indaba 2011 on Feb. 7-10, 2011 at the Cape Town International Convention Centre, Cape Town, South Africa, booth #204-206. United Spectrometer Technologies cc, a leading distributor of Thermo Scientific Niton XRF instruments, will be in the booth as well. The instruments of choice in elemental analysis solutions for mining and exploration, Thermo Scientific Niton analyzers can quickly determine the elemental composition of sample data at all stages of the exploration, mining and refining processes. Thermo Fisher Scientific is the world’s leading manufacturer of handheld x-ray fluorescence (XRF) analyzers.

Thermo Scientific geometrically optimized 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). This innovative technology also allows light element analysis of 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.

“More than 2,500 of our Thermo Scientific Niton XRF analyzers are already deployed in the global mining industry. With the launch of the Niton® XL2 GOLDD™ and enhanced Niton XL3t GOLDD+, mining companies of any size can access a range of products that is engineered from the ground up to withstand harsh mining environments, reduce laboratory costs and improve efficiency,” said Bob Wopperer, director of marketing and business development for Thermo Scientific Niton Analyzers.

“The Niton XL2 GOLDD is the ideal instrument for grade control, concentrator operations and near-mine exploration, while the Niton XL3t GOLDD+ is the analyzer of choice for advanced exploration and is a boon to the energy and industrial minerals markets. With the Niton XL3t GOLDD+, you get lab-quality analysis in the field, logging trailer or core room,” added Wopperer.

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 enhanced capabilities to identify elemental anomalies near the earth’s surface. Both instruments make it easy to perform trend analysis by averaging readings in real-time or by downloading results later to a PC. They deliver fast, accurate elemental analysis of soils/sediments, drill cuttings and drill core and outcrop for intensive exploration programs, whether base metals or precious metals.

– 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 particularly suitable for mine mapping, development and grade control where accurate elemental composition data is required across a large number of samples.

– Niton XL3t GOLDD+ analyzers with their 50kV, 200 ?A x-ray tube deliver fast, accurate analysis for intensive metals exploration, even helping to identify anomalies near the earth’s average crustal abundance. Further, the Niton XL3t GOLDD+ offers the unique, new Thermo Scientific TestAll Geo feature, which automatically determines the correct analytical test mode for rapid analysis of major, minor and trace elements in geological samples. In addition, the pseudo-elements feature allows users to calculate oxide weight percentage and ounce per ton Au equivalents as well as to enter cut-off grade.

A Family of Thermo Scientific Niton XRF Analyzers

Handheld, award-winning Niton XL2 Series and Niton XL3 Series XRF analyzers are purpose-built 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.

They 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 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.

Both series of analyzers offer users the choice of an out-of-the-box field mapping option or the flexibility of seamless integration with existing commercial mapping packages. Either way, these analyzers excel at storing results that are matched to GPS coordinates. Then these results can simply be downloaded to existing GIS and data analysis packages

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.
