Fake Gold:
Measuring gold purity using non-destructive methods based on Archimedes' principle
Taiwan Matsuhaku provides precision testing equipment from 0.01g to 0.00001g.
As shown in Figures 1 and 2 below.
Figure 1
Figure 2
The video shown is density determination using the buoyancy method.
All test results are displayed simultaneously after the test.
Gold density measurement is based on the hydrostatic weighing method.
It is direct application of the Archimedes’ principle.
This hydrostatic weighing method is to measure the mass of the sample in air and displaces its own volume of liquid.
Usually this method used for the calibration of hydrometer, solid and liquid density measurement, underwater weighing and purity precious metal measurement.
Density of a material is defined by its mass per unit volume of the material.
It can be stated in grams per milliliter (g/ml).
The purposes of measuring the material density are for material quality control, concentration determination and also to identify purity of precious metal.
Weighing balance and densimeter are among of the reliable instrument to determine the purity of gold using hydrostatic weighing method. Figure 1 and Figure 2 show the measurement of material using the densimeter and weighing balance respectively.
