Fuel cells produce electricity and heat electrochemically by combining oxygen from the air with a fuel, preferably hydrogen, from methanol, natural gas, or petroleum. Reformers are often used in conjunction with fuel cells

Analytical laboratory services detect, classify and/or assay chemical, material, biological, geological and environmental samples.

Plastics and plastic materials are organic, synthetic or processed polymers that are supplied as raw materials or stock shapes. They typically consist of thermoplastic or thermosetting resins and can be made into many forms.

NDT supplies and accessories are components, ancillary equipment, standards, and consumable materials used in non-destructive testing (NDT).

Environmental testing and analytical services provide testing of environmental samples such as soil, water, air, and industrial wastes or byproducts.

Corrosion and electrochemical instruments use a variety of methods to detect and measure corrosion and electrochemical conditions in plant machinery, field equipment, batteries, fuel cells, colloids, and other solutions or systems

Chemical testing services test, analyze, and certify a wide range of chemicals for purity, chemical compatibility, and environmental impact.

Chemical and material processing services modify or produce chemicals, powders, foods, minerals, rubber, plastics, adhesives, and other bulk materials on a contractual, toll or fee basis. Common processes include compounding, distillation, drying, formulation, mixing, blending, purification, extraction, synthesis, and powder milling.

Material testing services test, analyze, and certify a wide range of materials for purity, chemical compatibility, and environmental impact.

Thermoplastics and thermoplastic materials soften when heated and harden when cooled. They can withstand many heating and cooling cycles and are often suitable for recycling.

Chemical manufacturing and synthesis services providers manufacture or synthesize organic or inorganic chemicals on a contract basis.

Battery and fuel cell test equipment consists of specialized test stations, stands or systems, monitors and component modules for performance or endurance testing. 

Environmental consulting and engineering services provide design planning and assessment, project management, permit acquisition and other services

Engineering consulting firms provide engineering services and expertise to companies in need of a specialized skill-set.  Professionals in this category work with clients to define solutions to problems or to help determine and recommend the best course of action for a given initiative

Load cells are transducers for force and load measurement, often with mounting packaging.  They are widely used in testing, instrumentation, and as components in larger devices such as scales
