Thermo Fisher Scientific Introduces Mining Sample Collection and Preparation Tool Kits

New Application Note Highlights Use of Thermo Scientific Sample Collection and Preparation Tools to Improve the Efficiency of Portable XRF Analysis; Field Tests from a Base Metal Ore Deposit

Thermo Fisher Scientific Inc., the world leader in serving science, today published a new application note focusing on how its Thermo Scientific Mining Sample Collection and Preparation Tool kits can improve the efficiency of its portable x-ray fluorescence (XRF) instruments when analyzing heterogeneous rock samples. Three sets of analyses were conducted on samples from a mineralized drill hole in northwest Canada. Offering the instruments of choice in elemental analysis solutions for mining and exploration, Thermo Fisher is a pioneer in portable XRF technology.

With the proven analytical performance of Thermo Scientific portable XRF analyzers, such as the Thermo Scientific Niton XL3t GOLDD+, in the field at all stages of the exploration, mining and refining processes, the limiting factor in achieving better correlation with laboratory results is proper sample preparation. This limitation is particularly true for the analysis of elements lighter than calcium. For the XRF analysis of geologic materials, the analytical performance is improved by collecting representative aliquots and proper preparation of the sample, which these new tools make possible.

"Whether you're conducting a grass roots exploration or looking to improve your ore processes at an operating mine, the need for more information, with greater accuracy, precision and speed has driven the call for new tools and new solutions," said Jon Shein, senior director of marketing communications for Thermo Scientific Portable Analytical Instruments.

Shein continued, "With more than 3,000 Thermo Scientific portable XRF analyzers deployed in the global mining markets, we are helping to fulfill those needs. The field tests cited in our application note show how using sample preparation tools improve correlation with lab methods. Mining and exploration companies of every size use our analyzers daily to help them make informed decisions. Because we recognize that sampling techniques can greatly impact these results, and in our continuous efforts to bring the lab to the field, we are pleased to introduce our new sample collection and preparation tools."

Complementary Solution to XRF Analysis

Never before presented in a commercially available package, the Thermo Scientific Direct Rock Sampler Kit and the Thermo Scientific Electric Hammer Mill Kit offer a unique, complementary solution for XRF analysis in the field. The Direct Rock Sampler allows the collection of fine powders from a rock face or drill core samples, while the Electric Hammer Mill provides the rapid milling of samples and delivers a homogenized, fine powder in just seconds. These compact, portable, battery-powered tool kits provide everything needed to deal with geological materials for elemental analysis on-site to help deliver high-quality analytical data within minutes rather than days or weeks. The sample pellet press tool included with both kits generates a sample with a consistent flat surface and density, minimizing matrix effects; requires less than 5 grams of sample, reducing sample collection efforts; does not require sample film, which reduces light element performance.

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 portable XRF 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.
