Composition & Trace Element AnalysisKnow What You’ve Got: Inside and Out

LTI's Chemistry Lab performs element analysis, determines material composition and provides material characterization. Various instrumental chemistry and wet analysis methods are used throughout the Lab to test materials for chemical composition and element make-up. Our chemists analyze the composition of metals, ores, powdered metals, plastics, composites, ceramics, ferroalloys and other materials. Trace element analysis is performed by ICP spectrometers that detect elements to parts-per-million for many metals. Our composition analysis lab welcomes the challenge to process work with limited sample weight or specialized requirements.

Energy Dispersive X-ray Spectrometry or EDS is applied in conjunction with Scanning Electron Microscopy (SEM) analysis to detect and measure elements in or on the surface of the sample for qualitative analysis and/or quantitative information on elemental composition. The new SEM/EDS equipment at Laboratory Testing is particularly helpful in microanalysis and analyzing small areas of interest on samples.

Laboratory Testing also performs corrosion analysis services on metals using methods such as passivation, humidity, salt spray and salt fog testing.

Chemical and composition analyses are performed using the following methods:

  • Fourier Transform Infrared Spectroscopy (FTIR)
  • Energy Dispersive X-ray Spectrometry (EDS)
  • Atomic Emission Spectroscopy (AES)
  • Carbon/Sulfur/Nitrogen/Oxygen/Hydrogen Determination
  • Inductively-Coupled Plasma Atomic Emission Spectroscopy (ICP-AES)
  • Inductively-Coupled Plasma Mass Spectroscopy (ICP-MS)
  • Positive Material Identification (PMI)
  • Accelerated Intergranular Corrosion (ASTM Specifications)
  • Salt Spray (Salt Fog {ASTM B-117})
  • Sieve Analysis
  • Soxhlet Extraction
  • Plating Identification
  • Density, Porosity & Oil Content
  • Classical Wet Chemistry
  • Passivation Testing (ASTM specifications)
  • Humidity Testing
  • RoHS Compliance Testing (Wet analysis & spectroscopy)

RoHS Directive

The Restriction of Hazardous Substances Directive or RoHS Directive, was drawn up in the European Union to protect human health and the environment from hazardous substances. The directive applies to most manufacturers, sellers, distributors and recyclers of electrical and electronic components or equipment sold or used in the European Union.

The Directive restricts the use of six hazardous substances in these products - lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers. Laboratory Testing can help you assure compliance with quick, reliable chemical testing and analysis of your component materials to verify levels of the restricted substances. All of your answers will be fully documented in a Certified Test Report.
