CBNM certification of Cd in polyethylene by isotope dilution mass spectrometry
Four polyethylene materials have been certified for their cadmium content by isotope dilution mass spectrometry. To do so, a spike (enriched 111Cd) was characterised by reverse IDMS using high purity cadmium metal. The cadmium concentration certified in the polyethylene is 0.363, 0.676, 1.760 and 3.62 mmol/kg respectively (40.9, 75.9, 197.9 and 407 mg/kg respectively). These certified materials can be used in calibrating routine methods and measurements.
