App Notes

The Dioxin family consists of 210 compounds, of which 17 contain the 2,3,7,8 pattern of chlorination.

The determination of the thermostability of PVC (also called dehydrochlorination test or DHC test) characterizes the stability of polyvinyl chloride or related chlorinated polymers against heat exposure.

This Application Note describes the determination of copolymer levels in polyethylene (PE) and polyvinylacetate (PVA) pellets using NIRS.

The determination of the acid value, the hydroxyl value, and the isocyanates plays an important part in the analysis of raw materials for plastics. This application describes the determination of these characteristic values by automatic potentiometric titration.

Halogen and sulfur analysis in waste materials is crucial. The inline combination of the Mitsubishi combustion module with Metrohm IC offers the right tool for these types of samples.

The presence of excessive water in plastics adversely affects the performance of polymeric goods which is why water determination is of crucial importance.

The determination of the acid value, the hydroxyl value, and the isocyanates plays an important part in the analysis of raw materials for plastics. The present bulletin describes the determination of these characteristic values by automatic potentiometric titration.

Vitamin D3 (cholecalciferol) is essential for the human body. Low levels of vitamin D3 increase the risk of illness from a range of disorders.

This application note describes the pressurized solvent extraction of dioxins and furans from air filter samples (PUF and QFF) using the SpeedExtractor E-914.

Over the last half of the previous century, the use of partially hydrogenated vegetable oil (PHVO) replaced the use of animal fats for baking purposes in most western countries.
