Carbon dioxide (CO₂) lasers use the energy-state transitions between vibrational and rotational states of CO₂ molecules to emit at long IR, about 10 µm, wavelengths.

Gas generators provide an onsite supply of gas, vapor or humidity (water vapor) eliminating the need for delivery in gas cylinders.

Industrial gases are pure elements, molecular compounds or mixtures that are gaseous or vaporous at room temperature and pressure.

Gas sensors interact with a gas to initiate the measurement of its concentration.

Cryogenic equipment produces or is used in the production of very low temperature materials or processes.

Pharmaceutical and medical gases are specialized for medical, drug processing or biotechnology applications.

Gas and air instruments detect, monitor or analyze gases present in an environment.
