Plastics materials are used extensively in a wide variety of applications. One of the most important of these applications involves packaging materials. For example, plastics can be used in bottles containing soft drinks, in boxes containing food products, or in the packaging of raw materials during shipment. The analysis of off-odors in Polyethylene (PE) samples is very important toward detecting residual solvents as well as unexpected byproducts resulting from the manufacturing process. Additionally, the use of anti-oxidants or light stabilization may induce off odors.
Alpha MOS Sensor Array systems are specifically designed for the analysis, identification and recognition of complex odors, aromas and most volatile compounds. The FOX Electronic Nose is particularly suitable for identifying off-odors in polymers for food applications, like PE (Polyethylene) and PET (Polyethylene terephtalate).
