Isotope Ratio Mass Spectrometry (IRMS) has emerged as a critical analytical tool in the authentication of food products and the verification of their geographical origins. By precisely measuring the ...

Continuous flow stable isotope ratio mass spectrometer (Delta V Plus) for elemental and headspace isotope analyses (H, C, N, O) Continuous flow stable isotope ratio mass spectrometer (MAT 253 Plus) ...

Stable isotope techniques can help improve soil management and crop nutrition. To ensure the quality of stable isotope analysis through isotope ratio mass spectrometry (IRMS), appropriate sample ...

This EA-IRMS system can simultaneously measure δ 13 C and δ 15 N of bulk organic material, as well as quantify %-Carbon and %-Nitrogen of the sample. Potential samples include sediments, plant tissues ...

In mass spectrometry, a sample is analyzed to determine its molecular composition through the generation of a spectrum that reveals the masses of its component parts. A transfer line introduces the ...

yellow-colored areas are filled with Ar and He gases, respectively. Differential pumping systems are located after the doughnut-shaped gas cell as well as before and after the GCCB. (Credit: Niwase et ...

Qualitative analysis serves as the foundation for compound identification. It focuses primarily on determining the elemental composition and structure of analytes within a sample. Identifying the ...

Magnetic sectors were the mass analyzers used in the early days of mass spectrometry. Those instruments were quite large, and today, other, more compact, types of mass analyzers capable of separating ...

The discovery of stable ''isotopes" began with J. J. Thomson's identification of neon-22 in 1912 (Bievre et al., 1984). More than 90 naturally occurring elements have been identified on the earth; ...
