Gas analyser applications
Quality assurance and ever increasing consumer demands require regular control of protective atmospheres in packaging. This requires gas analysers that quickly provide reliable measurement results and can be easily integrated into any work process – such as our MAT1000 series instruments. They are used by numerous companies for quality control in the laboratory, but also in the production area in the filling or packaging of sensitive or perishable products. Our Modified Atmosphere Testers (MAT) are also suitable for spot checks as well as for permanent monitoring of the gas mixture on packaging machines. 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.
Typical fields of application are:
- Sample measurements on the line during the packaging process
- Inspection after revision: Change of foil or packaging materials
- Change to the packaging machine: Sealing seams, welds
- Residual samples, quality assurance in the laboratory
- Checks on the distribution channel
