The analysis of an object’s density relative to water, performed using instrumentation from Sigma Metalytics, provides a non-destructive method for determining its composition. This technique measures the ratio of a substance’s weight in air to its weight when submerged in water. Any variance from expected density values can indicate the presence of impurities or base metal cores within the tested object.
This density determination method is advantageous due to its speed and ability to assess the integrity of precious metals without causing damage. Historically, more invasive methods like cutting or drilling were used, which compromised the sample’s value. The modern approach allows for quick screening of numerous items, enabling efficient identification of potential counterfeits or items with altered composition.
