XRF Screening of Gold Silver and Platinum Jewellery Testing
The X-ray fluorescence (XRF) screening method is a non-destructive technique widely used in the precious metals sector to analyze the elemental composition of gold, silver, and platinum jewellery. This service ensures compliance with international standards such as ISO 9573-1 for gold, ISO 4968 for silver, and EN 12066 for platinum. XRF screening is particularly valuable in the precious metals testing industry due to its speed and accuracy.
Our state-of-the-art equipment allows us to perform rapid elemental analysis with high precision. The process involves a sample preparation step where jewellery items are cleaned of any impurities or contaminants that might interfere with accurate readings. After cleaning, the samples undergo XRF analysis using a spectrometer capable of detecting trace elements down to parts per thousand.
The data obtained from this process is used to determine the purity of gold (expressed in karats), silver, and platinum content according to international standards. For example, 24-karat gold contains pure gold with no other metals mixed in, while lower karat numbers indicate alloys containing varying amounts of copper, nickel, or zinc.
Our service offers several advantages over traditional destructive testing methods like fire assay or gravimetric analysis. XRF screening is faster, less expensive, and does not require the destruction of the sample. This makes it ideal for quality control during production as well as for verifying the authenticity and purity of jewellery items before sale.
Additionally, our service provides detailed reports that include not only the elemental composition but also any alloying elements present in the jewellery piece. These reports are crucial for ensuring compliance with legal requirements and maintaining trust among customers who value transparency regarding product quality.
We follow stringent quality assurance protocols to ensure consistent accuracy across all tests performed on your precious metals samples. Our team of experienced professionals uses advanced software tools to interpret results accurately, providing actionable insights that help improve processes within your organization.

Industry Applications
The application of XRF screening extends beyond just jewellery testing into various sectors including manufacturing, retail, and regulatory compliance. In manufacturing environments, it serves as a critical tool for quality assurance by quickly identifying any deviations from expected specifications during production runs.
Retailers benefit greatly from this service too; they can use it to verify the authenticity of products sold online or in-store against customer expectations regarding purity levels. This helps build consumer confidence and trust which is paramount in maintaining brand reputation.
From a regulatory standpoint, governments around the world have implemented strict regulations governing the sale of precious metals items based on their declared purity levels. Our XRF screening service ensures that these rules are adhered to by providing accurate data that supports compliance documentation required by law.
For R&D teams within organizations involved in developing new alloys or formulations for use in jewellery manufacturing, this technology provides valuable feedback on how close their prototypes match desired compositions. It also aids in troubleshooting issues related to inconsistencies seen across batches produced at different times.
Quality and Reliability Assurance
The reliability of our XRF screening service is underpinned by robust quality assurance practices that are consistently aligned with recognized standards. We ensure that every test conducted meets or exceeds industry expectations through rigorous calibration procedures, regular maintenance schedules for all equipment used in the process, and continuous training programs for personnel involved directly in performing these analyses.
A key aspect of our QA framework involves participating in inter-laboratory comparisons where results from different labs are compared against each other to identify any discrepancies and address them promptly. This helps maintain uniformity in testing across multiple sites worldwide.
We employ a multi-tiered approach to validation which includes method verification studies, proficiency testing programs, and participation in external audits conducted by regulatory bodies. These measures serve to reinforce our commitment to delivering reliable results that are trusted both internally within your organization as well externally among stakeholders who rely on the accuracy of these analyses.
Use Cases and Application Examples
In the manufacturing sector, XRF screening plays a pivotal role in maintaining consistent product quality by ensuring that each batch produced adheres strictly to specified alloy compositions. For instance, when producing 18-karat gold jewellery, it’s essential to maintain purity levels within narrow ranges; otherwise, discrepancies could lead to customer dissatisfaction or non-compliance issues.
Another use case involves verifying the authenticity of antique pieces before offering them for sale at auction houses. Here, the ability to provide detailed elemental analysis reports can add significant value by providing potential buyers with confidence in the provenance and quality of these items.
Retailers often utilize this service during their internal audits to check inventory against customer orders or when faced with complaints about discrepancies between advertised specifications and actual product contents. It allows them to rectify any mismatches promptly, thereby enhancing operational efficiency and customer satisfaction.
