Take a look at our Frequently Asked Questions below or download our brochure here.
What is Chrysos PhotonAssay?
Delivering faster, safer, and more accurate gold analysis, Chrysos PhotonAssay is a quantitative, chemistry-free replacement for Fire Assay on-site and in the laboratory.
What are the benefits of replacing Fire Assay with Chrysos PhotonAssay?
Chrysos PhotonAssay provides fully-quantitative analysis in as little as 3 minutes, delivers enhanced accuracy and precision, and ensures reduced operating costs for gold producers, polymetallic miners and laboratories across the globe.
What business benefits does Chrysos PhotonAssay afford gold producers?
Whether operating their own laboratory, or outsourcing to an external supplier, Chrysos PhotonAssay lets gold producers achieve faster, simpler and more accurate gold analysis on larger samples with reduced costs and safety risks.
Can polymetallic miners benefit from Chrysos PhotonAssay?
For polymetallic miners with gold as a by-product, Chrysos PhotonAssay helps achieve simple, cost-effective and accurate gold analysis on larger samples with improved throughput and safety outcomes.
How are assay laboratories using Chrysos PhotonAssay in their facilities?
Laboratories are using Chrysos PhotonAssay to differentiate their business and gain competitive advantage whilst reducing costs and improving customer service.
Is there a Chrysos PhotonAssay unit designed for both gold and polymetallic miners looking for fast, accurate analysis on a wide range of elements?
The PA1408X delivers faster, more accurate and economical gold analysis on larger sample sizes. Providing fully-quantitative results within minutes, the PA1408X offers all the value of Chrysos PhotonAssay across a wide range of elements.
Is there a Chrysos PhotonAssay unit suited to operations with space and operational resource constraints?
The PA0852N offers faster, more accurate gold analysis in a compact and cost-efficient package. With a smaller footprint and reduced power requirements, the PA0852N delivers the full value of Chrysos PhotonAssay on a targeted set of elements.
How does Chrysos PhotonAssay work?
Hitting samples with high-energy X-rays, Chrysos PhotonAssay causes excitation of atomic nuclei allowing enhanced analysis of gold, silver and complementary elements.
How is Chrysos PhotonAssay different from XRF?
XRF is less penetrating, making it impossible to measure bulk samples directly, and commercial units do not have the sensitivity to measure elements at gram-per-tonne concentrations.
What elements can Chrysos PhotonAssay measure?
Chrysos PhotonAssay provides enhanced analysis of gold, silver and complementary elements.
In what physical form must samples be?
Chrysos PhotonAssay allows large samples to be measured and provides a true bulk reading independent of the chemical or physical form of the sample. A single rock or section of core can be measured just as easily as a powdered or crushed sample, and solutions or slurries can also be directly analysed.
Can samples be re-used for further analysis?
Samples are sealed inside uniquely-numbered plastic jars before analysis and remain in the jar throughout the process. The Chrysos PhotonAssay analysis is completely non-destructive, and all samples can be retained for further analysis or testing if required.
Does Chrysos PhotonAssay use a radioactive source?
No. The Chrysos PhotonAssay X-rays are generated electronically using an electron linear accelerator. When the source is powered off, it produces no radiation.
How safe is the Chrysos PhotonAssay X-ray technology?
Chrysos PhotonAssay units include comprehensive safety measures, including custom-designed shielding, safety interlocks and control systems. All operations are fully automated, and no operators need enter the unit during the analysis process. X-ray levels outside of the units comply with Australian and international guidelines and are completely safe for operating personnel and members of the public.
Are there any special handling requirements for samples after analysis?
No. Even immediately after exposure to the X-ray beam, excitation levels are low, and samples can be safely handled.
