  • Energy‐resolved mass spectrometry for differentiation of the fluorine substitution position on the phenyl ring of fluoromethcathinones
    A reliable method for structural analysis is crucial for the forensic investigation of new psychoactive substances (NPSs). Towards this end, mass spectrometry is one of the most efficient and facile methods for the identification of NPSs. However, the differentiation among 2‐, 3‐, and 4‐fluoromethcathinones (o‐, m‐, and p‐FMCs), which are ring‐fluorinated positional isomers part of […]
  • Study of the cyanoacrylate fuming mechanism by matrix‐assisted laser desorption/ionization mass spectrometry
    Despite cyanoacrylate fuming being widely used in the forensic science field, its mechanism is not well understood. In this study, matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry is used to study latent fingerprints that have been cyanoacrylate fumed in an attempt to gain insight into the fuming mechanism. In the negative mode mass spectrometry data, four […]
  • LC‐DAD‐ESI‐MS/MS–based phenolic profiling and antioxidant activity in Turkish cv. Nizip Yaglik olive oils from different maturity olives
    The current study was designed to find out how olive maturity indices (2.5, 3.5, and 4.5) affect the individual phenolic compounds and antioxidant potencies of olive oils produced from cv. Nizip Yaglik olives. Liquid chromatography coupled to diode array detection and electrospray ionization tandem mass spectrometry in multiple reaction monitoring mode was utilized for the […]
  • Challenges in the identification process of phenidate analogues in LC‐ESI‐MS/MS analysis: Information enhancement by derivatization with isobutyl chloroformate
    A new analytical technique for the structural elucidation of four representative phenidate analogues possessing a secondary amine residue, which leads to a major/single amine‐representative fragment/product ion at m/z 84 both in their GC‐EI‐MS and LC‐ESI‐MS/MS spectra, making their identification ambiguous, was developed. The method is based on “in vial” chemical derivatization with isobutyl chloroformate in […]
  • Identification of G‐nerve agents at picogram levels from complex organic samples containing hydrocarbon interferences by aqueous extraction, followed by derivatization and liquid chromatography‐mass spectrometry analysis
    The chromatograms obtained from the gas chromatography‐electron ionization mass spectrometric (GC‐EI‐MS) analysis of extracts containing G‐nerve agents in the presence of diesel, gasoline, etc., are dominated by hydrocarbon backgrounds that “mask” the G‐nerve agents, leading to severe difficulties in identification. This paper presents a practical solution for this challenge by transferring the G‐nerve agents from […]

  • Multiple isotope tracers in fur keratin discriminate between mothers and offspring
    Rationale Isoscape origin models for mammals may be impaired by fractionation and routing of isotopes during lactation. Here, we tested if the stable carbon, nitrogen and hydrogen ratios of juvenile bats differ from those of their mothers and if derived isotopic dietary niches and geographical assignments vary accordingly between mothers and juveniles. Methods During the […]
  • Stable Isotope Measurements to Differentiate Sources of Monofluoroacetate in a Blackmail Case
    Rationale Stable isotope ratios can provide a ‘fingerprint' to enable differentiation of sources of monofluoroacetate (MFA) hence providing a means to eliminate potential sources of MFA in a blackmail case involving the contamination of milk. Methods The stable isotopic composition (δ2H, δ13C and δ18O values) of a library of 43 samples of MFA was determined […]
  • Investigations into the performance of travelling wave enabled conventional and cyclic ion mobility systems to characterise protomers of fluoroquinolone antibiotic residues
    Rationale Fluoroquinolones (FLQs) have been shown to form protomers with distinctive fragment profiles. Experimental parameters affect protomer formation, impacting observed conventional tandem mass spectrometric (MS/MS) dissociation and multiple reaction monitoring (MRM) transition reproducibility. Collision cross section (CCS) measurement can provide an additional identification metric and improved ion mobility (IM) separation strategies could provide further understanding […]
  • Single‐stranded DNA structural diversity: TAGGGT from monomers to dimers to tetramer formation
    Rationale DNA quadruplex structures have emerged as novel drug targets due to their role in preventing abnormal gene transcription and maintaining telomere stability. Trapped Ion Mobility Spectrometry–Mass Spectrometry (TIMS–MS), combined with theoretical modeling, is a powerful tool for studying the kinetic intermediates of DNA complexes formed in solution and interrogated in the gas phase after […]
  • Separation of biologically relevant isomers on an Orbitrap Mass Spectrometer using High Resolution Drift Tube Ion Mobility and Varied Drift Gas Mixtures
    Rationale Atmospheric pressure drift tube ion mobility is a powerful addition to the Orbitrap mass spectrometer enabling direct separation of isomers. Apart from offering high resolving power in a compact design, it also facilitates optimization of the separation gas, as shown here for a series of biologically relevant isomer pairs. Methods An Excellims MA3100 High […]
