oxygen analyser for modified atmosphere packaging

1. Oxygen Analyser
Headspace Oxygen Analyser
Summary : Modified Atmosphere Packaging (MAP) is now used commonly to enhance the shelf life
of food and pharmaceutical products that are sensitive to the presence of Oxygen or other gases.
The process of MAP involves flushing of nitrogen (or other gas / mixes) to displace the air inside the
package. Sometimes the flushing happens incorrectly or inadequately thereby allowing an
undesirable amount of oxygen to remain inside the package and reduce the shelf life or stability of
the product.
Test Method : A septum seal sticker is applied to the package (pouch / blister / tetra-pack / bottle,
etc and a needle in pushed through it. The gas inside is allowed to come out through the needle and
is analysed by an Oxygen (or other gas) sensor. The instrument shows the O2% directly.
Ambient air has 20.9% oxygen. MAP targets to flush out this air and bring down the O2 level to under
1.5%. Presence of O2 in excess of 2% can have a degrading effect in product stability and shelf life.
