Determination of multi-element content of gold alloy jewelry Laser ablation-inductively coupled plasma mass spectrometry

1 Scope

This document describes the use of laser ablation-inductively coupled plasma mass spectrometry for the determination of magnesium, titanium, chromium, manganese, iron, nickel, copper, Methods for zinc, arsenic, ruthenium, rhodium, palladium, silver, platinum, tin, antimony, iridium, cadmium, lead, and bismuth content:

This document is applicable to the determination of multi-element content in gold alloy jewelry with a gold content of not less than 990:00 per mille: The elements and measurement ranges are shown in Table 1:

4 Principles

Gold alloy jewelry is ablated by laser, and the fine particles produced are brought into the inductively coupled plasma mass spectrometry system by high-purity inert gas, and various components are measured:
