产品详细介绍
In November 2004, a large quantity of marine sediment was collected from Kilbrannan Sound, south east of the island of Arran, in the Clyde River estuary, Scotland, UK. The material was collected and supplied to the IAEA through collaboration with the QUASIMEME Laboratory Performance Studies Programme.
The material was freeze dried by QUASIMEME and sent to IAEA MEL for further processing and bottling. The dried, material was hand sieved (315 μm) by MESL staff. Approximately 70% of particles had sizes below 100 μm. Aliquots of about 25 g were packed into glass bottles with polyethylene caps and sealed in plastic bags.
Approximately five hundred units of the material were prepared. The homogeneity of this material for trace elements was tested using a standard protocol and found to be satisfactory.
