One of the most beloved Christmas desserts has long been the Christmas pudding. A dense, brandy and fruit-laden cake, whose origins date back to 14th century England. In the earliest versions of the pudding, a dried pea would be baked into the cake, a treasure that would supposedly bring good luck to whoever found it […]

Geochemical Research and Documentation Assistant – is an automated table sampler for portable and handheld analytical instruments such as pXRF. Portable Spectral Services has now acquired a GERDA, watch the video below to see it in action! Automated scanning of pulped samples River sediments Drill core AND MORE! https://www.youtube.com/watch?v=2ofz4F_ZRLo Recent Articles
In the field, lithium-ion batteries are what fuel an XRF. If a team is travelling to a location that is far from available electrical sockets, the days output becomes dependent on the charge of the XRF battery. A low battery can result in a day of low productivity. Here are five tips on how to […]
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 […]
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 […]
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, […]
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 that stimulate imagination, therefore, enabling users to process the information faster. Neuroscientists from MIT (1) have found that the human brain can process […]
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 […]
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 […]
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 a sample […]
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 […]
