Analysis Method

Most elements are determined by high resolution ICP‑MS using sample preconcentration. The results are an average of three aliquots subsampled from three samples representative of the batch. The samples are slowly evaporated to dryness. The resulting residue is reconstituted in a small volume of 2% Nitric Acid / 2% Hydrogen Peroxide ROMIL‑UpA. Operations are conducted under Class 100 or better clean-room conditions. For volatile elements (eg, Hg), the acid samples are diluted then directly injected into the ICP‑MS. Values below 3 times the standard deviation of the blank are shown with '<', no blank value is subtracted.
