產(chǎn)品詳細(xì)介紹
IAEA-417Marine Sediment Inorganic Sediment
A bulk sediment sample was collected from the Venice Lagoon, Italy. This sediment was deep-frozen, dried, ground and sieved through a 250 μm stainless steel sieve. The sediment fraction of particle size less than 250 μm was homogenized by mixing it in a rotating drum for two weeks. Then, aliquots of about 40 g were packaged into glass bottles with aluminium screw caps and sealed with Teflon tape.
