Gas analysis

The earth surrounds a shell of gases - the protective atmosphere. Such protection is also used in the food industry, in modified atmosphere packaging (MAP). How does quality assurance use the possibility of Modified Atmospheric Tester (MAT) for their processes?

Packing under protective atmosphere

According to estimates by the Federal Institute for Risk Assessment (BfR), about 90 per cent of fresh meat in the self-service section of supermarkets is packaged in a modified atmosphere. This allows food producers to provide the consumer with first-class quality product over a long period of time. But how does this process work?

Gas analyser applications

Manufacturers of sensitive or perishable products must guarantee first-class quality over long periods of time. This applies especially to the food industry, but also to the electronics, pharmaceutical or cosmetics industry. Gas analysers are used by many companies for quality control in the laboratory, but also in the production area in the filling or packaging of sensitive or perishable products.
