Simultaneous δ15N, δ13C and δ34S measurements of low biomass samples using a technically advanced high sensitivity elemental analyzer connected to an isotope ratio mass spectrometer

T. Hansen, A. Burmeister and U. Sommer

Leibniz-Institute for Marine Sciences at Kiel University, Dusternbrooker Weg 20, 24105 Kiel, Germany

Rapid Communications in Mass Spectrometry (2009), V23, pp3387–3393, doi: 10.1002/rcm.4267

Goal: Conventional simultaneous CNS stable isotope abundance measurements of solid samples usually require high sample amounts, up to 1mg carbon, to achieve exact analytical results. This rarely used application is often impaired by high C:S element ratios when organic samples are analyzed and problems such as incomplete conversion into sulphur dioxide occur during analysis. We introduce, as a technical innovation, a high sensitivity elemental analyzer coupled to a conventional isotope ratio mass spectrometer, with which CNS-stable isotope ratios can be determined simultaneously in samples with low carbon content (<40mg C corresponding to ca. 100mg dry weight).

Determination of the natural abundance δ15N of taurine by gas chromatography–isotope ratio measurement mass spectrometry

Illa Tea*, Ingrid Antheaume, Jorick Besnard and Richard J. Robins

Elucidation of Biosynthesis by Isotopic Spectrometry Group, Unit for Interdisciplinary Chemistry: Synthesis-Analysis-Modelling University of Nantes–CNRS UMR6230, 2 rue de la Houssinie`re, BP 92208, F-44322 Nantes, France

Rapid Communications in Mass Spectrometry (2010), V24, pp3380–3386, doi: 10.1002/rcm.4784

Goal: The measurement of the nitrogen isotope ratio of taurine (2-aminoethanesulphonic acid) in biological samples has a large number of potential applications. Taurine is a small water-soluble molecule which is notoriously difficult to analyze due to its polarity and functionality. A method is described which allows the determination of the natural abundance d15N values of taurine and structural analogues, such as 3-amino-1-propanesulphonic acid (APSA), by isotope ratio mass spectrometry interfaced to gas chromatography (GC-irm-MS).

Determination of the natural abundance δ15N of nortropane alkaloids by gas chromatography–isotope ratio mass spectrometry of their ethylcarbamate esters

Katarzyna Kosieradzka, Illa Tea, Emmanuel Gentil and Richard J. Robins

Elucidation of Biosynthesis by Isotopic Spectrometry Group, Unit for Interdisciplinary Chemistry: Synthesis-Analysis-Modelling (CEISAM), University of Nantes—CNRS UMR6230, 2, rue de la Houssinière, 44322 Nantes, France

Analytical Bioanalytical Chemistry (2010), V396, pp1405–1414, doi: 10.1007/s00216-009-3354-z

Goal: A method is described which allows both the quantification of nortropane alkaloids and the determination of their natural abundance δ15N values. The protocol exploits the derivatisation of the alkaloids by reaction with ethyl chloroformate in aqueous medium and the quantitative extraction of the ensuing ethylcarbamate esters. The improved chromatographic properties of these derivatives gives ample separation of the isomeric nortropine and norpseudotropine for measurement of their δ15N (‰) values by isotope ratio mass spectrometry interfaced to gas chromatography. Adequate separation could not be achieved with the underivatised compounds. Repeatability and precision are sufficient to allow differences in the δ15N values (Δδ15N)>0.8‰ to be measured, with a standard deviation routinely ∼0.3‰. The methodology has been tested by determining the changes in the δ15N values of nortropine and norpseudotropine during degradation by cell suspension cultures of a Pseudomonas strain expressing a specific capacity for tropine catabolism. The precision and reproducibility are shown sufficient to allow the evolution of the δ15N values to be followed during the fermentation.
