Instrument: CHN Elemental Analyzer
A CHN Elemental Analyzer is used for the determination of carbon, hydrogen, and nitrogen content in organic and other types of materials, including solids, liquids, volatile, and viscous samples.
Nearly all particulate carbon and nitrogen measurements were done using by collecting seawater particles onto glass-fibers filters (i.e., GF/F) and quantified using an elemental analyzer. Particulate phosphorus was quantified using the ash-hydrolysis method
