Metals and oxides in sediment cores from St. Louis River and Lake Superior, Minnesota, USA

DOI

Method1: HCl-extracted sample analysis for major metals. Instrument: Thermo Scientific iCAP 6500 dual view ICP-OES (Inductively Coupled Plasma - Optical Emission Spectrometer). Power: 1150 W - Neb flow: 0.65 liters/min - Cooling gas: 12 liters/min - Aux gas: 0.5 liters/min - 1 ml/min sample flow rate. Integration: 8 sec/replicate and 5 replicates/sample - Mira Mist Peek nebulizer.Method 2: Trace metals analysis of freeze-dried sediments. Instruments: Thermo Scientific XSERIES 2 ICP-MS w/ ESI PC3 Peltier cooled spray chamber, SC-FAST injection loop, and SC-4 autosampler. Samples were diluted appropriately and 20 ppb of In internal standard was added. All elements were analyzed using He/H2 collision-reaction mode.Method 3: Freeze-dried sediment processed for major oxides, units parts per million. Instrument: Thermo Scientific iCAP 6500 dual view ICP-OES (Inductively Coupled Plasma - Optical Emission Spectrometer). Power: 1150 W - Neb flow: 0.65 liters/min - Cooling gas: 12 liters/min - Aux gas: 0.5 liters/min - 1 ml/min sample flow rate. Integration: 8 sec/replicate and 5 replicates/sample - Mira Mist Peek nebulizer.
