The Precious Metal Detection Liquid is a stannous chloride solution used to determine that no more precious metal is dissolved in aqua regia or saltwater solutions.

Precious metals are just that: precious. Therefore detecting metals in solutions must be simple so that precious metals aren't left behind.

• This liquid detects gold, silver and platinum group metals (including platinum, palladium, rhodium, iridium, ruthenium) by changing color.
• Each precious metal makes a unique and vivid color change.

• Used to test for the presence of dissolved precious metals in chloride solutions.
• Sensitive down to 4 parts of precious metal per million parts of solution
• Recommended use on spot plate or mirror for the most sensitive results.

• Requires only a drop or two of solution to test
• One bottle is usually sufficient for a hundred or more tests
