Chemical testing services test, analyze, and certify a wide range of chemicals for purity, chemical compatibility, and environmental impact. Tested products include adhesives and sealants, ceramics and glass, concrete and mortar, chemicals and coatings, composite materials, fuel cells, metals, nanomaterials, paper, petroleum, plastic, polymers, powders, soil, rubber, textiles, water, welds and joints. Test media and services are the most important specifications to consider when searching for providers of chemical testing services. Available services include ash testing, atomic absorption spectroscopy, chemical extraction, chromatography, combustion, deformulation or reverse engineering, diffraction, plasma emission spectroscopy, infrared spectroscopy, mass spectroscopy, microscopy, metallography, optical emission spectroscopy, particle size or sieve analysis, property testing, rheology, scanning electron microscopy, standards testing or certification, thermal analysis, wet chemical analysis, and X-ray fluorescence. Some chemical testing services test chemicals that are used in aerospace, automotive, marine, medical military, pharmaceutical or packaging applications. Other test chemicals are used in electronic devices, semiconductors, or integrated circuits (ICs). Selecting chemical testing services requires an analysis of testing methods. Ash testing quantifies fillers and inorganic pigments. Atomic absorption (AA) spectroscopy uses light absorption to measure the concentration of gas-phase atoms. Chemical extraction removes elements through a reaction with a solution. Combustion is an exothermic chemical reaction due to rapid oxidation. Diffraction evaluates crystal structure, grain size, texture and/or residual stress. Chemical analysis with inductively coupled plasma spectroscopy (ICP) excites atoms for atomic emission spectroscopy and ionizes atoms for mass spectrometry. Infrared (IR) spectroscopy measures the wavelength and absorption intensity of infrared light. Microscopy uses instruments such as optical and electron microscopes to study the structure and composition of materials. Particle size analysis includes sieving, dynamic light scattering, electrozone sensing, and laser diffraction (LALLS). Property testing measures electrical, thermal, mechanical, or chemical characteristics. Rheology analyzes fluids based on viscosity and elastic response. Thermal analysis includes calorimetry, thermogravimetric analysis (TGA), dynamic thermal analysis (DTA). Other testing methods include chromatography, optical emission spectroscopy, scanning electron microscopy (SEM), wet chemical analysis and X-ray fluorescence (XRF) spectrometry.

Other testing methods include chromatography, optical emission spectroscopy, scanning electron microscopy (SEM), wet chemical analysis and X-ray fluorescence (XRF) spectrometry. Chemical testing services are located across the United States and around the world. Some companies test or certify chemicals according to U.S. military specifications (MIL-SPEC) or standards from the American Society of Mechanical Engineers (ASME), the American Society for Testing and Materials (ASTM), or the American Welding Society (AWS). Other companies test or certify chemicals according to requirements from original equipment manufacturers (OEMs). Facility accreditations and assessments ensure that chemical testing services meet requirements from organizations such as the American Association for Laboratory Accreditation (A2LA) and the International Standards Organization (ISO). Facility accreditations also include National Aerospace and Defense Contractor (NADCAP) requirements, the National Voluntary Laboratory Accreditation Program (NVLAP), and Nationally Recognized Testing Laboratory (NRTL) certification.
