An international team of researchers, led by scientists from GSI/FAIR in Darmstadt, Germany, has studied r-process ...

Stable isotope probing (SIP) experiments in conjunction with Raman microspectroscopy (Raman) or nano-scale secondary ion mass spectrometry (NanoSIMS) are frequently used to explore single cell ...

Demand for the ornaments, jewelry, and other luxury items carved from the ivory in elephant tusks has led poachers to ...

The 24-year-old athlete Francisco Lo has accepted a three-year period of ineligibility for an anti-doping rule violation by ...

USADA has issued a four-year ban to American powerlifter Nicolas Recio for an anti-doping violation. The 29-year-old tested positive for an anabolic ...

Scientists from the Shanghai University of Sport in Shanghai, China recently developed a new gas chromatography (GC) combustion isotope ratio mass spectrometry (GC/C/IRMS)-based procedure for ...

Since this measurement was made for isotopes, a new name Orbitrap IRMS (Orbitrap isotope ratio mass spectrometry) was coined. “The isotope of phosphate in the phytate molecule was untouched by any ...

Another key feature of mass spectrometry is that it provides a unique signature for each molecule, enabling the detection of specific components and differentiation between isotopes. Certain mass ...

Conclusions: The results obtained with the tested diet groups highlight the importance of adapting the criteria if one wishes to increase the sensitivity of exogenous testosterone detection. In ...

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 ...
