Chemical Testing

We provide chemical analysis for metals/alloys, ores & minerals, polymers/rubber, lubricants, water and construction materials. Methods follow client-specified IS/ASTM/ISO standards (as applicable). Reports include method, specimen traceability, results tables, and a clear conclusion vs. acceptance criteria.
