IMS-401
Pulverised Basalt Oxide Blank Au, Pt, Pd, 1kg jar
IMS-401 is a certified reference material (CRM) designed for quality control in the analysis of gold (Au), platinum (Pt), and palladium (Pd) in mining and exploration laboratories. Certified in accordance with ISO Guide 35:2017 and ISO 17034:2016, this CRM is manufactured from a homogenized pulverized basalt rock, serving as a blank or low-concentration control material for fire assay methods.
Key Features
- Certified Concentrations: Precisely validated values for Au (2 mg/t), with Pt and Pd reported below detection limits (<5 mg/t and <2 mg/t, respectively).
- Method-Specific Validation: Certified for lead collection fire assay with ICP-OES/ICP-MS finish, validated across 12 ISO/IEC 17025-accredited laboratories.
- Supplied in 1kg press-sealed plastic jars, with 50-100g sachets available upon request for blind laboratory submissions.
- Validity: 10 years when stored sealed in cool, dry conditions.
