What Makes Uranium Glass? | Micro-XRF

Uranium glass glowing under UV light

To delve into a deeper understanding of uranium glass, such as its elemental makeup, micro-XRF is the perfect technique for measurement. Providing visualisation at a high-spatial resolution up to 4µm, combined with its output data, the micro-XRF conducts in-depth non-destructive elemental analysis.   Background As antiques go, uranium glass is one of the most unique […]

A Guide to Portable XRF Calibrations

The portable XRF has many calibration options, which are designed to analyse a wide variety of materials. With so many on offer it is easy to feel overwhelmed when trying to choose the best calibration option for your application. This is why Portable Spectral Services are going back to calibration basics and looking into what […]

Micro-XRF – An analysis of Microelectronics

Currently there is a global shortage of semiconductors due to the COVID-19 pandemic crippling the semiconductor manufacturing industry. Chip shortages are expected to run well into 2023, meaning some industries will be opting for repair options over delayed replacement of printed circuit boards (PCBs). PCBs pose two major hurdles when it comes to repair. Firstly, […]

Enhancing Geochemical Visualization in Exploration: Part 2

micro XRF elemental scan of gold. Includes Al, Si, K, Au, Hg.

Part 1 One of the fastest ways for humans to store information in their long-term memory is to pair concepts with meaningful images. Visual learning has been found to have cognitive effects which stimulate imagination, therefore, enabling users to process the information faster. Neuroscientists from MIT (1) have found that the human brain can process […]

Enhancing Geochemical Visualization in Exploration: Part 1

Four micro XRF elemental scans

Geochemical visualization of identified chemical trends is challenging during exploration when data is limited. While geochemical assay datasets are highly valuable, the use of visual tools can often simplify the ability to identify and track chemical and mineralogical trends and display the key characteristics of an exploration target to a wider audience. To quote American […]

Heavy Mineral Concentrates for mineral exploration

micro XRF scan of heavy mineral concetrates

Download our HMC Brochure Australia is the home to the world’s largest heavy mineral deposits containing titanium, zircon, and rare earth elements as well as heavy mineral concentrates (HMC) extracted from surficial sediments in alluvial, fluvial, glacial and wind environments. Early-stage exploration and processing of heavy minerals utilises techniques such as gravity and magnetic separation […]

RAMAN Spectroscopy: Rapid identification of lithium bearing minerals

Bruker BRAVO Raman spectral instrument

Field identification of mineral phases within LCT pegmatite systems has been made simple with the handheld Bruker BRAVO Raman with duo laser excitation (Figure 1). Figure 1. Bruker’s handheld BRAVO Raman What is Raman spectroscopy? Raman is a form of vibrational spectroscopy that generates a spectrum by directing a monochromatic light from a laser onto […]

What is your money really worth? | Micro-XRF

micro-XRF elemental map of coins

Over the course of Australian history the coins used in circulation have changed multiple times from hole-punched Spanish coins to Dutch guilders, English pennies and now the Australian Dollar. One of the issues we have faced during these transitions is when the material value of the coin outweighs its value as a currency. What is […]

Delivering Christmas joy with the micro-XRF

Christmas stamps

Portable Spectral Services (PSS) are getting into the Christmas spirit as we scan a pair of vintage Australian postage stamps dated from 1973 using micro-XRF. Figure 1. 1973 Australian Christmas stamps, designed by George Hamori. a) The baptism of Christ with the words “This is My Beloved Son”, b) The Good Shepherd with the words […]

Detecting Low Level Gold by BRUKER pXRF

Portable PPB detector process to detect gold with pXRF

Historically, detecting low levels of gold in the field with pXRF has been a challenging process with no truly accessible methodologies available. Portable ppb Pty Ltd’s DetectORE™ technology brings compatibility for the detection of low-level gold by pXRF analysis. DetectORE™  is a patented technology to detect gold at low level concertation’s (<20 ppb) using a portable XRF such as […]

The New and Improved S1 TITAN Models

Bruker S1 TITAN with computer

At the beginning of 2021, Bruker released an exciting announcement that the Bruker S1 TITAN portable XRF models were receiving an upgrade. Following in the steps of the TRACER 5g, these improved S1 TITAN models will be receiving the new and improved graphene window. Most notably, this graphene window will replace the use of an 8 µm beryllium window […]

Rare Earth Elements: The most critical and strategic elements on the planet

Rare Earth Elements calibration screen S1 TITAN

Introduction The dominance of China in the rare earths industry has forced the USA, Russia, European Union, Japan, Australia, and other counties to formulate policies and implement strategies to ensure security and sustainability of rare earth elements (REE) to reduce dependency on Chinese supplies. Notably, in 2020 the European Union’s report on critical raw materials […]
