Size reduction of elastic plastics with volatile components

Neutral-to-analysis sample preparation for the detection of PAH and phthalates

Polynuclear aromatic hydrocarbons, also known as PAH, are used as plasticizers in many caoutchouc products such as, for example, rubber grips of tools. Some PAH have a proven carcinogenic effect on humans; that is why there are critical limits for the maximum concentration in consumer products. Phthalates are used as plasticizers in plastics such as PVC. Recent tests (of the German consumer magazine “test”, issue 09/2009, p. 72ff.) have shown that these harmful substances occur in such sensitive products as children’s pushchairs. Not only PAH was found but also chlorinated paraffin and flame retardants which are considered as harmful to health.
