Reference carbon and nitrogen concentrations, and isotope ratios from alfalfa, nylon-6, bovine liver, and enriched alanine

Abstract:

This dataset includes results of carbon and nitrogen analyses on reference materials including alfalfa, nylon-6, bovine liver, and enriched alanine. The reference materials were analyzed for Carbon, Nitrogen, delta-13C, and delta-15N by the Stable Isotope Facility, U.C. Davis using a PDZ Europa ANCA-GSL elemental analyzer interfaced to a PDZ Europa 20-20 isotope ratio mass spectrometer (Sercon Ltd., Cheshire, UK).

Instruments

Elemental Analyzer

Supplied Name: PDZ Europa ANCA-GSL elemental analyzer

Supplied Description:

Used for chemical and isotope analyses.

Instrument Type

Generic Name: Elemental Analyzer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB01/

Generic Description:

Instruments that quantify carbon, nitrogen and sometimes other elements by combusting the sample at very high temperature and assaying the resulting gaseous oxides. Usually used for samples including organic material.

Isotope-ratio Mass Spectrometer

Supplied Name: PDZ Europa 20-20 isotope ratio mass spectrometer (Sercon Ltd., Cheshire, UK)

Supplied Description:

Used for chemical and isotope analyses.

Instrument Type

Generic Name: Isotope-ratio Mass Spectrometer

Acronym: IR Mass Spec; IRMS

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB16/

Generic Description:

The Isotope-ratio Mass Spectrometer is a particular type of mass spectrometer used to measure the relative abundance of isotopes in a given sample (e.g. VG Prism II Isotope Ratio Mass-Spectrometer).

Parameters
