Analytical laboratory services detect, classify and/or assay chemical, material, biological, geological and environmental samples. They perform many different services. Examples include quantitative analysis, bioanalytical services, chemical testing, cleanroom testing, environmental exposure, environmental testing, failure analysis, field sampling, sample pickup, sample retention, standards testing, and report preparation. Analytical laboratory services that provide geotechnical, industrial hygiene, material testing, and umpire testing services are also available. Monitoring programs, audits, and site surveillance programs can be designed for specific test media or material such as adhesives, air, asbestos, ceramics, chemicals, coatings, composites, concrete, fuel cells and battery materials, gases, hazardous waste, herbicides and pesticides, metals and heavy metals, inorganics, microbiological samples, nanomaterials, paper, dioxins, petroleum fluids, plastics and rubber, polymers and organics, powders, and radioactive materials. Analytical laboratory services may also specialize in test media such as sediment, soil, solid waste, toxins, textiles, thin films, volatile organic compounds (VOC), wafers, water, and welds.
