Modified atmosphere packaging gas analyzer

Modified atmosphere packaging (MAP) process is designed to increase shelf life of food products and medicine. This technique consists of replacing ambient air – composed by 20,9% of oxygen and 78% of nitrogen – by other gases and substances to create a « vacuum » in headspace packaging of food products.

MAP headspace gas analyzer

MAP headspace gas analyzerThe main objective of modified atmosphere packaging and headspace gas is to enhance products lifetime. This process oftentimes modifies the oxygen concentration (O2) inside the packaging to include other gases that will slow down oxidation (chemical reaction) and germs growth & development. 


Each food type has its own specific modified atmosphere in order to get the most effective preservation. For example, the recommended modified atmosphere for apples is set at 5% of oxygen, 5% of carbon dioxide and 90% of nitrogen. For red meat, the ideal modified atmosphere for retail is composed of 70% of oxygen and 30% of carbon dioxide. To guarantee packaging compliance, safety and accurate measures, using a headspace gas analyzer is essential. This kind of detector requires regular calibration.

Headspace gas analyzer benefits

Headspace gas analyzer benefitsThe Oxybaby® portable headspace gas analyzer has many assets:

  • Very small gas sample needed – that does not modify protective atmosphere composition – no risk of degradation
  • Automatically controlled flow with alarm event in case of sampling needle obstruction
  • Measurements data history can be reached on the device to compare previous results
  • Large backlit display for easy readings in any situation
  • Easy transport thanks to rechargeable battery
  • Shockproof plastic casing for harshest environments
