Fractional–Rational Calibration for Laser-Induced Breakdown Spectroscopy (LIBS) Analysis of Steels with High Matrix Variability
Read more: https://doi.org/10.1177/00037028261456320
#SAS #Spectroscopy #LIBS #Calibration #steel

Abstract: The results of an original calibration methodology that accounts for interelement influences in the analysis of alloyed steels using laser-induced breakdown spectroscopy (LIBS) are presented. The results were obtained from a dataset of spectra provided for the regression competition at the LIBS 2022 conference and available online. The dataset includes spectra from 41 steel samples with known concentrations of major alloying elements (chromium, nickel, manganese, molybdenum, carbon, silicon, copper) and 15 samples with unknown compositions for model validation. The concentration of alloying elements varies over a wide range, with iron content ranging from 98% to 41%. To reduce spectral line position instability, we applied a preprocessing method that maximizes the correlation of each spectrum with the first spectrum in the dataset. The implementation of the developed calibration methodology led to an improvement in the root mean square error of the analysis, with reduction factors ranging from two (for nickel and molybdenum) to five (for manganese and chromium) when compared to classical calibration.

The distinctive feature of Przybylski's Star is the predominance of many Ce Il lines in its spectrum. This means that this ion is highly overabundant.
For example, the abundance of Cell in the Sun is about 10,000 times lower!

Raman Spectroscopy of Biofluids: Fusion Strategies for Detecting Oral Potentially Malignant Disorders and Oral Cancers

Abstract: Minimally invasive screening tools are essential for early detection of oral cancers to reduce mortality. A key necessity is the ability to differentiate highly heterogeneous oral potentially malignant disorders (OPMDs) and cancers. This study evaluated serum and salivary Raman spectroscopy (RS) for detecting OPMDs and oral cancers. Blood and saliva were collected from 13 non-habitual controls (NHC), 13 tobacco habitués (HC), 10 leukoplakia (L), 25 oral submucous fibrosis (OSMF), and 14 oral squamous cell carcinoma (OSCC) subjects. Raman spectra were acquired, pre-processed, and analyzed using multivariate methods. Serum outperformed saliva in individual classification models, achieving accuracies of 92%, 85%, 100%, 88%, and 85% for NHC, HC, L, OSMF, and OSCC, respectively. Saliva, despite its non-invasive advantage, showed higher misclassification among HC, L, OSMF, and OSCC. Low-level fusion of serum and saliva spectral data improved the classification of OSMF, OSCC, and NHC groups compared to saliva models. Mid-level fusion surpassed both biofluids, reaching 100% accuracy for NHC, L, and OSMF. Multivariate curve resolution–alternating least squares analysis of serum revealed altered protein- and lipid-related features among groups. These findings demonstrate the potential of serum and salivary RS, particularly with data fusion, as effective tools for OPMD and oral cancer screening.

Split the light from a star into a spectrum and you can investigate what the star is made of, how hot it is and even whether it is moving towards or away from us.
