Whether you’re sampling for exploration, development or production, getting asset data is a critical part of your workflow. Traditionally, it can take weeks to access this data, causing delays and drastically affecting productivity.
Portable XRF Gun X-ray technologies have made it possible to achieve real-time chemical and elemental analysis in the field, but despite all of the hype, they’ve never reached their full potential. Portable XRF is a terrific technology but the problem is the industry treats it as a point solution. This leads to problems with using the technology effectively in the field to generate good data at the point of sample measurement, and also managing the data after it’s been collected. We recognize this and we also recognize that using these machines effectively is not just about the gun.
There are four barriers that have been holding XRF Guns back from reaching its full potential within the industry:
- Lack of training for using the technology effectively;
- Challenges with managing data once generated;
- Complications with global logistics and transport of radiology equipment;
- High upfront cost to access XRF technology.
We created an XRF package to overcome these barriers and provide XRF technology that can deliver the full value it was designed for.
Firstly, we’ve reinvented the interface and written our own software to ensure that optimal readings are taken every time. This means that technology is available to geologists but also drilling and field crew. Secondly, the data generated by the XRF gun is validated in the field at the point of data collection, transmitted to XRF Hub and is then available in real time to geologists anywhere in the world. Once in the Hub, the XRF data can be used in conjunction with other data types, such as your geological logging, survey or orientation data.
So, now we can see it being used in the field, how do you get it there? As an industrial radiology device, the XRF unit can be difficult to transport across state and country borders due to strict policies from customs with this type of equipment. With our global network of Reflex offices and distributors, you don’t need to worry about all of those transport and logistics problems. Making our XRF readily available is the third way we’ve improved the technology. The fourth way we improved the XRF is to make it available for hire, which makes it even more accessible for you.
XRF SOLUTION FEATURES
By automating the time consuming processes such as QA/QC, data validation, database cleaning and formatting, geologists have more time for geology.
Project planning, workflow and Standard Operating Procedures
The XRF Gun solution automates vital processes to ensure data quality and data interoperability within multiple existing platforms. The XRF Gun software has been optimised for geological applications. Workflow, operating procedures and parameters have been standardised within the software to simplify sample collection and ensure data quality and productivity is maximised. Real-time monitoring also allows QC data to be assessed as the data are generated.
Data collection and validation
The XRF Gun solution allows you to configure the operating parameters [count time optimisation, mode and beam settings] and design your own project specific data validation (QA/QC) rules. These rules are built into the data collection routine with immediate feedback on instrument values outside acceptable ranges on blanks, standards and duplicates. The XRF Gun solution allows users to rectify data quality problems at the time of collection rather than when it is too late.
Data access, backup and security
The XRF solution allows users to upload files into HUB, data can then be accessed through the internet from any networked device. Secure, multiple access to the data reduces the risk of error, mismanagement and duplication. The data backup in HUB includes the raw data spectrum and machine state information which is invaluable where data is in doubt as it reveals other matrix and operational conditions that may impact on the data.
The Geochemistry Team is highly experienced in spectral analysis and can provide the most comprehensive and reliable information about your data.
Data extraction and migration
Data is retrieved from the XRF unit in a structured way for further processing and/or storage without multi-handling of the dataset. Data from multiple XRF units are aggregated automatically without duplication. Results may be accessed through HUB from any internet connection for further processing and advanced modelling in software platforms such as ioGAS and Leapfrog.
HUB
The cloud computing environment offered by the HUB allows customers to develop a common operating solution. Within the HUB, data are transformed into information and delivered in near real time, in a unified format, to decision-makers.

HOW TO USE A XRF GUN ANALYZER
Let me show you how quick and easy it is to use your Olympus Delta XRF Analyzer right out of the case, and how to be safe when using it.
When you first open the case, you’ll find the shipping papers and documentation for your Delta, your Delta Analyzer, two lithium-ion batteries,
the Cal Check coupon, USB cables, a USB drive that includes software and user documentation, either Kapton or Prolene windows
and the AC adaptor for the docking station.
Underneath the first layer of protective foam you’ll find the docking station and the AC adaptor for the Analyzer if you bought one.
To use the Analyzer, pull open the battery latch and insert one of the fully-charged batteries, then close the latch. The batteries only go in one way.
If the battery isn’t sliding into position, take it out, rotate it, and slide it back in. Press the power button on the top of the Analyzer. After it powers up, the radiation safety notice appears. After you read it, tap start.
Because this is your first time using the Analyzer, it will need a calibration check. The Calibration Check or Cal Check makes sure that the Analyzer is working correctly.
The Analyzer will need a Cal Check approximately every 10 hours, whether it’s being used for those 10 hours or not.
Put the Cal Check coupon on a flat surface and place the Analyzer window on the coupon.
Tap the Cal Check icon on the Analyzer screen. Cal Check will take less than 30 seconds.
Cal Check is an X-ray test, so the red X-ray indicator will be flashing to warn you that X-rays are being emitted.
This is a good time to talk about X-ray safety. As long as you use your Delta Analyzer correctly, and follow the recommended testing techniques and safety precautions found in your manual, you and everyone around you will be safe.
Our instruments are secure and dependable, but there are a few things that are important for you to know. When the red light is flashing, X-rays are being emitted. Never point the Analyzer at yourself. Never point the Analyzer at anyone else.
Never place your hand in front of the Analyzer window.
Once Cal Check is done, your Analyzer is ready to use. Your Analyzer has been configured to your specifications. The Delta in this video has been configured for metal allow identification, so we are going to test some metal.
Deltas with an allow calibration will have the window guard system installed. For premium and professional models capable of testing lighter elements, you must remove the window guard window and change your mode to Alloy Plus to test for these elements.
Testing is a short, simple, 3-step process. Place, test, view the result. Your Delta is configured to end testing when an alloy has been identified, so you don’t have to determine when a test has ended. As soon as a test is over, you can go on to the next test. Remember, when the X-ray indicator is flashing, X-rays are being emitted. When the X-ray indicator is solid red, the X-ray tube inside the Analyzer is powered on, but not emitting X-rays. The battery in the Analyzer should last for about 4 hours.
All Deltas have hot-swappable batteries, so you don’t have to power down the Analyzer just to put in a fresh battery.
To swap batteries, just open the battery latch, pull out the battery and insert a fresh one. A countdown screen shows you how much time you have to complete the swap. Once the fresh battery is in, you can keep right on testing.
When you are using the Delta for any length of time, place it in the docking station. The docking station will automatically run a Cal Check, automatically charge the battery in the Analyzer and automatically charge the backup battery.
As long as the Analyzer is powered on, the docking station will recognize it. The status of both batteries will be displayed on the Analyzer screen and a Cal Check will be performed automatically.
CONFIGURING AND EXPORTING THIS XRF GUN
