At METS Lab, we specialize in precise and reliable analysis of the chemical composition of metals, which plays a vital role in quality control, material certification, failure analysis, and compliance with international specifications. Accurate determination of elemental content ensures that metals meet performance, safety, and regulatory standards across industries such as aerospace, automotive, construction, energy, and manufacturing.

Why Chemical Composition Analysis Matters 

Understanding the elemental composition of metals allows manufacturers and engineers to: 

• Confirm alloy grades and material specifications 

• Ensure conformity to international standards (ASTM, ISO, DIN, etc.) 

• Control production quality and process consistency 

• Prevent material failures in critical applications 

• Comply with import/export and procurement requirements 

Analytical Techniques Used at METS Lab

Our state-of-the-art laboratory is equipped with advanced instrumentation for metallic analysis, including: 

• Optical Emission Spectroscopy (OES) – Fast and accurate bulk elemental analysis for ferrous and non-ferrous alloys. 

• X-ray Fluorescence (XRF) – Non-destructive analysis ideal for quality screening and alloy sorting. 

• Inductively Coupled Plasma – Optical Emission Spectrometry (ICP-OES) – High-sensitivity trace element detection. 

• Atomic Absorption Spectroscopy (AAS) – Precise quantification of specific metals. 

• Combustion & Inert Gas Analysis (LECO) – Determination of carbon, sulfur, oxygen, nitrogen, and hydrogen content in metals. 

International Standards Followed 

• METS Lab adheres to globally recognized testing protocols, including: 

  • ASTM E415 – Standard Test Method for Analysis of Carbon and Low-Alloy Steel by Spark Atomic Emission Spectrometry. 
  • ASTM E1086 / E1251 – OES methods for Fe, Al, Cu, Ni, Ti, and Zn alloys. 
  • ISO 14284 – Steel and iron – Sampling and preparation of samples for chemical analysis. 
  • ISO 17025 – General requirements for the competence of testing and calibration laboratories (our lab operates under this accreditation for quality assurance). 
  • ASTM E572 – Standard Test Method for Analysis of Stainless and Alloy Steels by Atomic Absorption Spectrometry. 
  • ISO 10204 – Metallic products – Types of inspection documents (used in certification of analysis reports).
