This publication is intended to support the proper use of the compound specific stable isotope (CSSI) technique for identifying sources of sediment within agroecosystems. Based on the measurement of ...

Isotope Ratio Mass Spectrometry (IRMS) is a powerful analytical technique used in food authentication and origin tracing. This method allows researchers to analyze the isotopic composition of ...

This instrument is optimized for the isotopic characterization of mixtures of organic molecules at trace quantities (~10ng per compound for carbon, ~100ng per compound for hydrogen) which provides ...

Stable isotopes can be used by measuring their amounts and proportions in samples, for example in water samples. Naturally-occurring stable isotopes of water and other substances are used to trace the ...

Increasing abundance of plastic waste has alarmed the society, but the environmental fate of microplastics has been difficult to trace. A research ... fatty acids using stable isotope mass ...

It is the first bioavailable strontium isotope map to show predicted strontium isotope ratios across all of Sub ... Strontium isoscape of sub-Saharan Africa allows tracing origins of victims of the ...
