产品详细介绍
IAEA-408Sediment (Tagus estuary, Portugal) Inorganic Sediment
A large sediment sample was collected from the mudflats of the Tagus estuary. This sediment was deep-frozen, freeze-dried, ground and sieved through a 150 μm stainless steel sieve.
The sediment fraction of particle size less than 150 μm was homogenized by mixing 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.
