When asked about what gases are used for, the most common answers are diving, welding and in medicine. This is natural because these are situations where the gas is seen in operation.

For instance when the local workshop fine tunes the car ignition, the result is checked with the help of instruments calibrated with specialty gas mixtures.
When diving really deep you need aid of specialty gas mixtures to avoid caisson disease. One of the first applications a child meets today, and remembers, is helium filled balloons. On the coming pages are some examples of application fields where HiQ® specialty gases can make a difference.
