Fluoride‐containing bioactive glasses and glass‐ceramics in the SiO2‐P2O5‐CaO‐CaF2 system are of great interest for dental applications, where the precipitation of fluorapatite supports tooth remineralization. Fluorine quantification in those glasses is key to estimate thermal properties and crystallization tendency. This work presents a study on fluorine determination by laser induced breakdown spectroscopy (LIBS) in four melt‐derived glass powders with varying P2O5 concentrations. LIBS enables fluorine quantification with a reduced analysis time, minimal to no sample preparation, and high spatial resolution. The fluorine calibration curve was obtained from CaF2 and SiO2 mixtures as reference samples, and the fluorine loss upon glass melting has been determined as a function of P2O5 content. The P2O5‐free glass shows the lowest fluorine loss (13%), with HF volatilization likely being responsible for the loss. By contrast, the glass with the highest P2O5 content (11.33 wt%) exhibits the largest fluorine loss (55%), owing to additional mechanisms involving the volatilization of phosphorus species like POF3.

Animal origin food products, including fish and seafood, meat and poultry, milk and dairy foods, and other related products play significant roles in human nutrition. However, fraud in this food sector frequently occurs, leading to negative economic impacts on consumers and potential risks to public health and the environment. Therefore, the development of analytical techniques that can rapidly detect fraud and verify the authenticity of such products is of paramount importance. Traditionally, a wide variety of targeted approaches, such as chemical, chromatographic, molecular, and protein-based techniques, among others, have been frequently used to identify animal species, production methods, provenance, and processing of food products. Although these conventional methods are accurate and reliable, they are destructive, time-consuming, and can only be employed at the laboratory scale. On the contrary, alternative methods based mainly on spectroscopy have emerged in recent years as invaluable tools to overcome most of the limitations associated with traditional measurements. The number of scientific studies reporting on various authenticity issues investigated by vibrational spectroscopy, nuclear magnetic resonance, and fluorescence spectroscopy has increased substantially over the past few years, indicating the tremendous potential of these techniques in the fight against food fraud. It is the aim of the present manuscript to review the state-of-the-art research advances since 2015 regarding the use of analytical methods applied to detect fraud in food products of animal origin, with particular attention paid to spectroscopic measurements coupled with chemometric analysis. The opportunities and challenges surrounding the use of spectroscopic techniques and possible future directions will also be discussed.

In the present work, laser‐induced breakdown spectroscopy (LIBS) was used to differentiate between different black toners of printers and photocopiers based on their elemental composition. Measurements were performed on 23 toner samples of different printers and six different photocopiers (of different brands and models). The LIBS spectra were compared to characterize each toner type. Multivariate statistical analysis based on PCA and graph clustering was used to develop a discrimination model between the toners in questioned documents. Good discrimination of both brand and model toners was obtained. The results may be beneficial for forensic applications in the investigations of questioned documents.
