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.

Proteins have specific biological functions in cells through conformational changes and interactions. Therefore, precise, in ...

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 ...

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

BAKER, S., BARR, D., DRISKELL, W. et al. Quantification of selected pesticide metabolites in human urine using isotope dilution high-performance liquid chromatography/tandem mass spectrometry.

The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.

The goal of quantitative proteomics is to determine the identity and relative quantity of each protein present in two or more complex protein samples. Here we describe a novel approach to quantitative ...
