Combustion IC for the simultaneous quantification of halogens in polymers

Halogen and sulfur determination

Halogen and sulfur determination in three PVC-containing power cable insulation materials using combustion IC. In addition to a high chloride content of up to 25%, low amounts of fluoride (< 30 mg/L) and sulfate (< 75 mg/L) were determined. Bromide, which elutes at approx. 9 min, was not detected. Column: Metrosep A Supp 4 - 250/4.0; eluent: 1.7 mmol/L Na2CO3, 1.8 mmol/L NaHCO3, 1 mL/min; sample volume: 10 μL; sample amount: 10 mg finely cut polymer material; internal standard: 10 mg/L phosphate.
