![]() Quantitative analyses were performed using a special gas-inlet system with a vacuum by which the sample can be transferred to a mass spectrometer, reducing the risk of contamination. Qualitative analyses were positive in all gaseous samples. For the detection of helium, central/peripheral blood samples and gaseous samples from the esophagus, stomach, and upper and lower respiratory airways (from the trachea and the primary left and right bronchia) were collected with a gastight syringe, ensuring minimal dilution. A successful gas analysis was performed following the suicide of a 17-year-old female. However, helium is a colorless and odorless inert gas that unfortunately cannot be detected using standard toxicological analysis. ![]() Inhaled-gas suicides can easily be assessed through death scene investigation and autopsy. ![]() Helium is also available in bulk gas and liquid delivery, as well as in a full range of purities and tank sizes.Suicide by helium inhalation has become increasingly common in the last few decades in Europe and the US because it produces a quick and painless death. We offer helium in high-pressure gas cylinders and liquid dewars-available in a variety of sizes-to meet any and all low-volume needs. Mixed with argon, it’s also used to inflate airbags.įrom purging hydrogen systems to pressurizing fluid systems, helium is essential to aerospace and aircraft applications both in flight and on the ground. Helium is used to test for leaks and ensure quality in automotive parts like fuel tanks and radiator systems. Used for more than just filling balloons, helium is widely used in the retail industry in refrigeration systems. Also, helium’s low boiling and melting points make it ideal for cooling applications. Used as a carrier gas in gas chromatography, helium is essential for determining sample content and characteristics. In order to capture high-resolution imagery of internal organs and tissues, these machines use superconducting magnets that need liquid helium to reach the cryogenic temperatures at which they operate. Helium is essential for operating MRI and NMR machinery. In heat-treating processes, helium is added to furnace atmospheres to produce stronger, more durable parts. Helium is utilized for its inert properties such as providing ideal arc temperatures for welding materials with high-heat conductivity.
