The ECS 4010 Nitrogen / Protein Analyzer is an elemental combustion analyser for CHNSO elemental analysis and Nitrogen / Protein determination. The GC oven and separation column have a temperature range of 30-110 degC, with control of +/- 0.1 degC.
Bulk nitrogen and carbon isotopic composition were determined using an isotope ratio mass spectrometer (DeltaPlusXP or Delta-V-Advantage) coupled to an elemental analyzer (Costech Model 4010).
Water column particle filters were analyzed for carbon content using a Costech Instruments Elemental Combustion System 4010 owned and operated by Dalhousie University.

Carbon and Nitrogen amounts and isotopic composition was measured with a Costech Elemental Analyzer attached to ThermoFinnigan MAT 253 isotope ratio mass spectrometer at the University of Washington Isolab facility in the Department of Earth and Space Sciences (Seattle, WA).
Total nitrogen and carbon were quantified with a Costech 4010 CHNOS Elemental Combustion system according to U.S. Environmental Protection Agency Method 440.0 (Zimmermann et al., 1997).
