Used as an inert, thermally stable fluid in specialized heat transfer systems and electronic testing due to its high dielectric strength. Commonly employed as a carrier medium in blood substitutes and oxygen-perfused cell culture systems because of its ability to dissolve large amounts of oxygen. Also utilized in semiconductor manufacturing for vapor phase deposition and as a tracer gas in leak detection owing to its chemical inertness and detectability at low concentrations. Its non-flammable and non-reactive nature makes it suitable for use in high-vacuum systems and as a damping fluid in sensitive instruments.
