Foreword
GB/T 17418 "analysis of noble metals in geochemical samples Method" is divided into seven parts.
--- Part 1. General rules and regulations;
--- Part 2. platinum and rhodium content - Determination of thiourea enrichment - catalytic polarography;
--- Part 3. Determination of palladium content - Preconcentration by thiourea - Graphite furnace atomic absorption spectrophotometry;
--- Part 4. Determination of the amount of iridium-enriched thiourea - Catalytic spectrophotometry;
--- Part 5. Determination of the amount of ruthenium and osmium distillation - Catalytic spectrophotometry;
--- Part 6. platinum, palladium and gold contents - fire assay enrichment - Emission Spectrometry;
--- Part 7. Determination of nickel sulphide fire assay gold platinum group elements - Inductively Coupled Plasma Mass Spectrometry.
