- Abstract:
- Reference Material (RM) also used as Proficiency Test (PT) materials were developed for trace metals including lead, cadmium, copper and iron in drinking water where 28 to 31 local laboratories participated in the PT scheme. The PT material was characterized for homogeneity and stability. Reference values were determined using double isotope dilution Inductively Coupled Plasma – Mass Spectrometry (ICP-MS). The PT was organized by the Industrial Technology Development Institute (ITDI) in the Philippines in accordance with ISO/IEC 17043:2010.
