Optical isotope ratio spectroscopy – complementing isotope ratio mass spectrometry
OSA Optical Sensors and Sensing Congress 2021 (AIS, FTS, HISE, SENSORS, ES), 2021Isotope ratio measurements and scale definitions are typically related to mass specectroscopy. This work discusses the challenges of optical isotope ratio spectroscopy and its prospects to significantly complement isotope ratio mass spectrometry.

Isotope ratio mass spectrometry
The Analyst, 2009Isotope Ratio Mass Spectrometry (IRMS) is a specialized technique used to provide information about the geographic, chemical, and biological origins of substances. The ability to determine the source of an organic substance stems from the relative isotopic abundances of the elements which comprise the material.

Rapid Communications in Mass Spectrometry, 1999
Of all the elements, hydrogen has the largest naturally occurring variations in the ratio of its stable isotopes (D/H). It is for this reason that there has been a strong desire to add hydrogen to the list of elements amenable to isotope ratio monitoring gas chromatography/mass spectrometry (irm-GC/MS). In irm-GC/MS the sample is entrained in helium as

Fast Gas Chromatography Combustion Isotope Ratio Mass Spectrometry
Analytical Chemistry, 2007We report here the first coupling of fast GC to IRMS, in a system capable of 250 ms peak widths (fwhm) at 1 mL/min flow rates, one-fifth as narrow as any previously reported GCC-IRMS system. We developed an optimized postcolumn interface that results in minimal peak broadening, using a programmable temperature vaporization injector in place of a rotary

High-precision continuous-flow isotope ratio mass spectrometry
Mass Spectrometry Reviews, 1997Although high-precision isotope determinations are routine in many areas of natural science, the instrument principles for their measurements have remained remarkably unchanged for four decades. The introduction of continuous-flow techniques to isotope ratio mass spectrometry (IRMS) instrumentation has precipitated a rapid expansion in capabilities for

Gas Source Isotope Ratio Mass Spectrometry (IRMS)
2014Gas source isotope ratio mass spectrometry is usually referred to as isotope ratio mass spectrometry (IRMS) or stable-isotope ratio mass spectrometry (SIRMS). IRMS is a conventional method for measuring isotope ratios and has benefited from more than 65 years of research and development.

Desulfurization of black powder for isotopic profiling using isotope ratio mass spectrometry
Forensic Science International, 2022The stable isotope analysis of black powder is of utmost significance with regard to its further comparison and traceability in explosion-related cases. To date, only a limited number of studies have reported the stable isotope analysis of black powder using isotope ratio mass spectrometry (IRMS).
