Helium, compressed. Helium (from Greek: ἥλιος, romanized: helios, lit. 'sun') is a chemical element; it has symbol He and atomic number 2. It is a colorless, odorless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table.

Helium, Ultra High Purity (UHP) (MOLE 99.999%) 3(d) Impurities and stabilizing additives which are themselves classified and which contribute to the classification of the substance. No applicable information is available.

Ultra high purity Helium is the most common grade used for multiple gas applications in gas chromatography.

Helium does not support life. It can act as a simple asphyxiant by diluting the concentration of oxygen in air below the levels necessary to support life. Adverse Health Effects. Helium is non-toxic and inert. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death.
