| CSIA-AA comparison between live polyps and outer proteinaceous skeletal material in three taxons of North Pacific deep-sea corals | Gas Chromatography Combustion Isotope Ratio Mass Spectrometry (GC/C/IRMS). For AA δ13C analyses, the derivatized AAs were injected in split mode at 250°C and separated on a DB-5 column (50 m x 0.5 mm inner diameter; 0.25 mm film thickness; Agilent Technologies, Santa Clara, California, USA) in a Thermo Trace Ultra gas chromatograph (GC) at the University of California, Santa Cruz. The separated AA peaks were analyzed on a Finnegan MAT DeltaPlus XL IRMS interfaced to the GC through a GC-C III combustion furnace (960°C) and reduction furnace (630°C).
