For your analysis and quality control

Air Liquide Healthcare has over 20 years of experience in providing gases such as nitrogen and associated equipment to the Australian market. Our highly-qualified staff strive to serve all of our patients and customers as professionally, effectively and efficiently as possible.

Nitrogen is mainly found in the atmosphere where it accounts for approximately 78% by volume of the air we breathe. In gaseous form, nitrogen is a neutral and colourless inert gas that does not sustain life.

In the healthcare field, nitrogen is used pure or in mixtures for various medical and non-medical analysis and quality control applications and to preserve living tissues and cells at cryogenic temperature.

We supply nitrogen in cylinders, in liquid vessels and dewars or through pipelines.

Typical applications

  • Analytical use as a zero and balance gas
