This method is often used by professionals in the precious metals industry due to its precision and ability to analyze without damaging the item. While XRF testing may be more costly than alternative methods, it is highly reliable for determining gold purity.
In summary, correctly assessing the purity of gold is essential for anyone involved in buying or selling this valuable metal. Grasping the carat system, using acid testing, and considering advanced methods like XRF testing can help buyers make knowledgeable decisions.
