THE CERTIFICATION OF THE IMPURITY CONTENTS (AG, AS, BI, CD, CU, NI, SB, SE, SN, TE, TL AND ZN) IN THREE GRADES OF LEAD
The report describes the certification of three lead reference materials. CRM 286 is electrolytically refined lead, CRM 287 is thermally refined lead and CRM 288 contains added impurities. They were analyzed for twelve elements using a wide range of techniques in 20 laboratories. The concentration of each determined element in each material is shown on the table below. The values given in brackets are not certified. The materials are available in two forms : square blocks (e.g for emission spectrometry or x-ray fluorescence) and chips for wet chemical methods.
