Analysis of the volatile organic compounds in grave soil using solid phase microextraction coupled to gas chromatography mass spectrometry (SPME-GC-MS) 2024 109 Locating and recovering bodies that are buried in clandestine graves is a challenging task and may provide significant information about the deceased in a forensic investigation. Currently, human remains detection (HRD) dogs are the most commonly use...
Classification of cannabinoids using mass spectral data to assist in the identification of novel synthetic cannabinoids 2024 166 Detection and characterization of newly synthesized cannabinoids (NSCs) is challenging due to the lack of availability of reference standards and chemical data. Identifying these substances usually involves the use of intelligence gathering or prior ...
Analysis of biogenic amines in vitreous humor using high performance liquid chromatography for the estimation of postmortem interval 2024 70 A novel method is proposed to estimate the postmortem interval (PMI) using the biogenic amine concentration in vitreous humor. There are multiple methods that can be used to determine the time of death (PMI). However, these methods often have uncerta...
Reversed-phase liquid chromatography for separation of illicit drugs utilizing water-rich mobile phases 2023 127 Reversed-phase high-performance liquid chromatography (RP-HPLC) is a widely accepted method in drug and toxicological analyses to detect and quantify drugs and metabolites. However, current RP-HPLC methods use mobile phases that contain significant ...
Classification of drugs of abuse using mass spectral data for the identification of novel psychoactive substances 2022 293 Novel psychoactive substances (NPSs) have been increasingly reported in recent years and possess significant risks to public health worldwide. These substances, sometimes known as “legal highs”, are newly designed drugs that mimic the effects of comm...
Determination of biogenic amines in decomposition odor using gas chromatography mass spectrometry 2021 624 In a forensic investigation of missing persons or a suspected murder the detection of the corpse is often the most important piece of evidence. Human remain detection dogs (HRD) are the most common method used in locating human remains. Although thes...
