Recent forensic applications of enhanced chromatographic separation methods

Abstract

This study reviews the recent applications of enhanced separation methods employed in forensic analysis utilizing gas chromatography, liquid chromatography, and supercritical fluid chromatography published between 2015 to 2020, except papers previously covered in relevant review articles. Applications of enhanced chromatographic separation methods to arson investigations, environmental forensics, sexual assault investigations, drug analysis, and toxicology are discussed. Future directions for enhanced chromatographic separation methods in forensic science are also explored.

Analytical strategies for herbal Cannabis samples in forensic applications: A comprehensive review

“…The most frequently applied techniques for forensic cannabis analysis are gas chromatography (GC) and liquid chromatography (LC) (Young & Lurie, 2022; Zivovinovic et al, 2018). Analytical methods often produce a large and complex amount of data that need multivariate data analysis to get the desired information (Granato et al, 2018; Oliveri et al, 2020).…”

Interpol review of fire debris analysis and fire investigation 2019–2022

“…Young and Lurie wrote a review article covering literature published between 2015 and 2020 on forensic applications of enhanced separation methods, including GC, LC, and supercritical fluid chromatography [ 45 ]. One section of this paper was devoted to fire debris analysis and primarily discussed the use of comprehensive 2D GC with different detectors for the identification of ignitable liquids.…”

Supercritical fluid chromatography with post‐column addition of supporting electrolyte solution for electrochemical determination of tocopherol and tocotrienol isomers

“…SFC is a developing chromatographic technique that is expected to provide faster separation with higher resolutions in comparison with HPLC and GC [1][2][3][4][5][6]. Detection in SFC is mainly performed by UV visible absorption [7] Article Related Abbreviations: ECD, electrochemical detection; FL, fluorescence detection; IS, internal standard; αT, α-tocopherol; αT3, α-tocotrienol; βT, β-tocopherol; βT3, β-tocotrienol; γT, γ-tocopherol; γT3, γ-tocotrienol; δT, δ-tocopherol; δT3, δ-tocotrienol and MS [8,9], but other detection methods have also been applied in SFC to enhance its performance and application.…”
