What instrument measures gold?

Answer 1

1. For the determination of the impurities concentration in gold emission spectrometers, atomic absorption spectrophotometers, internally coupled plasma (ICP or ICP-MS) spectrometers are used.

2. For the determination of the percentage of gold in alloys chemical methods of analysis and X/ray spectrometry are used. In jewelry stores standard acid solutions, standard needles and a special stone are used.

Answer 2

here is the karat system, and the millesimal

finess

system.

In the karat (also spelled carat), the purity of gold is given as a fraction of 24.

Karats=

24 x (mass of pure gold in sample / total mass of sample)

Thus, 24 karat is 100% pure, because it has 24 parts of pure gold per every 24 parts alloy;

18 karat is 75% pure, because it has 18 parts of pure gold per 24 parts, and so on.

In the millesimal

system, they simply denote the purity of gold in parts per thousand.

Thus, 750 parts pure gold per thousand total parts of alloy has a millesimal

value of

750. (75% pure gold). And 50% pure gold would have a value of 500.

Answer 3

Gold is weighed with a balance.
