Chemical Testing is one of the most essential scientific processes in modern industry. It ensures that raw materials, finished products, and environmental samples meet quality, safety, and regulatory standards.
At METS Lab, our ISO/IEC 17025-accredited chemical testing services support industries ranging from pharmaceuticals and food to construction, manufacturing, and water treatment.
Through advanced chemical analysis, we determine the composition, purity, and performance characteristics of materials according to global standards — including ASTM, ISO, BIS, AOAC, and EPA.
Chemical testing helps industries guarantee that every material used or produced is safe, compliant, and high-performing.
It identifies and quantifies the chemical components in solids, liquids, gases, or mixtures using precise analytical methods.
Key Benefits of Chemical Testing
Chemical testing combines qualitative (what’s in it) and quantitative (how much is in it) analysis using methods such as titration, spectroscopy, chromatography, and elemental analysis.
