Field portable X-ray fluorescence (FP-XRF) as powerful, rapid, non-destructive and ‘white analytical tool’ for forensic sciences - State of the art

FP-XRF (field portable X-Ray Fluorescence Spectroscopy) is a powerful tool for element determination, both quantitatively and qualitatively. FP-XRF due to its rapid, non-destructive, and cost-effective nature is crucial in forensic sciences where evidence preservation is essential. However, analytical calibration poses a significant challenge. These devices incorporate computational algorithms, but their use remains controversial, resulting in the technique being semi-quantitative. The article aims to review the versatile use of FP-XRF as a valuable forensic analysis tool. With its innovation, affordability, speed, non-destructive nature, and ability to perform in situ analysis, FP-XRF is becoming increasingly important. This review addresses the lack of a comprehensive summary and critical analysis of FP-XRF's role in forensic analyzes. We believe as technology continues to advance, it is likely that FP-XRF will become even more important and popular in the field of forensic sciences.
