“…The applications of IRMS analyses now extend far beyond their initial uses. For instance, IRMS instruments are employed to discriminate between organic and conventional agricultural practices, or in geographical origin traceability experiments. , These analyses are also fundamental in differentiating between endogenous and exogenous steroids in antidoping applications in sports . In line with Nier’s later research interests, IRMS-based analyses of chondrites have provided key evidence for the Giant Impact Theory of lunar origin .…”

This Perspective pays homage to Alfred Otto Carl Nier, whose substantial contributions were fundamental in shaping the mass spectrometry field into a key technology in research and industry. On the 30th anniversary of his passing, on May 16, 1994, this paper explores Nier's role in the field of mass spectrometry through an overview of his published works, key interviews, and archival material. Nier, originally an electrical engineer turned physicist, spent most of his scientific career at the University of Minnesota. His many innovations, both instrumental and methodological, encompassed advanced fields such as isotopic research, tracer studies, geochronology, or space research. Nier improved sector mass spectrometers, participated in the development of the isotope-ratio mass spectrometry field, developed a double-focusing sector mass spectrometer, and was a relevant member of the Manhattan Project. Today, Nier's influence persists, inspiring new generations of scientists engaged in cutting-edge research, from environmental studies to planetary exploration. His legacy thrives as current technologies and scientific strategies still echo his innovations and foresight.

“…Bulk stable isotope ratio (SIR) analysis is a promising tool for discerning organic authenticity in various produce categories. This technique has been effectively applied to differentiate vegetables [ 3 , 7 , 9 ], fruits [ 10 , 11 ], and cereals [ [12] , [13] , [14] , [15] ], either as a supplementary or alternative approach to pesticide residue screening. The SIR methodology primarily capitalizes on the discernible isotopic value disparities between applied fertilizers and the isotopic fractionation inherent in different production modes.…”

“…As the societal demand for sustainable agriculture grows, the authenticity of organic and green foods has become an urgent issue due to profit-driven practices such as false advertising and misleading labels [5]. Several effective analytical methods have been used to ensure their authenticity, primarily including stable isotope analysis [6], spectral analysis [7], and chemical analysis [8]. In these methods, stable isotopes (δ 13 C, δ 15 N, δ 2 H, and δ 18 O) can objectively reflect climatic conditions (temperature, humidity, light intensity, and precipitation), soil composition, and agricultural input (fertilizers, pesticides, etc.)…”

Seasonal (temporal) variations can influence the δ13C, δ2H, δ18O, and δ15N values and nutrient composition of organic (ORG), green (GRE), and conventional (CON) vegetables with a short growth cycle. Stable isotope ratio mass spectrometry (IRMS) and near-infrared spectroscopy (NIRS) combined with the partial least squares-discriminant analysis (PLS-DA) method were used to investigate seasonal effects on the identification of ORG, GRE, and CON Brassica chinensis L. samples (BCs). The results showed that δ15N values had significant differences among the three cultivation methods and that δ13C, δ2H, and δ18O values were significantly higher in winter and spring and lower in summer. The NIR spectra were relatively clustered across seasons. Neither IRMS-PLS-DA nor NIRS-PLS-DA could effectively identify all BC cultivation methods due to seasonal effects, while IRMS-NIRS-PLS-DA combined with Norris smoothing and derivative pretreatment had better predictive abilities, with an 89.80% accuracy for ORG and BCs, 88.89% for ORG and GRE BCs, and 75.00% for GRE and CON BCs. The IRMS-NIRS-PLS-DA provided an effective and robust method to identify BC cultivation methods, integrating multi-seasonal differences.
