Summary: In this paper, the content of chemical elements in waste was determined using ICP-OES and WDXRF techniques. To overcome the limitations of expensive and time-consuming analyses, a quick and inexpensive method for preliminary identification of the chemical composition of tested samples was developed. The samples were prepared as durable tablets for X-ray measurements. The limits of quantification were determined, and the uncertainty of the results was estimated by comparing them with a calibration method using standards and certified reference materials.

Summary: To analyze trace evidence at crime scenes, non-destructive or low-sample analysis techniques are preferred. One such technique is solid sampling ETV-ICPOES, which requires only a small amount of sample. This article discusses the capabilities of ETV-ICPOES in forensic analysis and presents various methods for analyzing physical evidence. Internal standardization and multivariate analysis are used to compensate for sample loading effects and enable quantification and discrimination of evidence. The article also explores future perspectives for utilizing ETV-ICPOES in forensic settings.

Summary: This study compares the derivatization procedures of putrescine, spermine, spermidine, and cadaverine in home-made wine samples using different reagents. The procedures were compared in terms of simplicity, linearity, precision, and accuracy. The derivatives of polyamines were isolated and characterized, and the structures of aliphatic amines were determined. The results suggest that the derivatization with 1-fluoro-2-nitro-4-(trifluoromethyl)benzene is a better choice for the determination of these compounds in food samples.
