Summary: This study is the first to use DART-MS for the rapid quantification of cannabidiol (CBD) in CBD oils. The results show that the quantification of CBD by DART-MS is highly correlated with a validated LC-MS method. The relative standard deviation values of the DART-MS measurements are below the acceptable limit, demonstrating that DART-MS is a reliable and cost-effective alternative method for CBD oil quality control.

Summary: Ink classification is the task of distinguishing unknown inks into different groups, while ink source prediction is the ability to predict the manufacturer or model of an unknown ink. This study presents an approach to predict the source of black inks using real-time mass spectrometry analysis and assesses the strength of the prediction using likelihood ratios. The results demonstrate the effectiveness of the proposed method in predicting ink source and calibrating the likelihood ratio.

Summary: Synthetic cannabinoid receptor agonists (SCRAs) are the largest and most defiant group of abuse designer drugs, with potent effects and severe consequences. Due to their ever-changing structure, limited information is available to the scientific community and law enforcement. This study provides new insights into the synthesis, pharmacology, and toxicity of SCRAs, identifying potential illegal psychoactive substances and their neurotoxicity on neuronal cells.

Summary: Fingermark patterns have long been used for biometric identification. Recent research has focused on the molecular composition of fingermark residue to gather information about the donor's profile. By analyzing fingermarks from thirteen donors using machine learning approaches, we demonstrate the potential of fingermark chemical composition to differentiate individuals with an accuracy ranging from 80% to 96%. While it is premature to apply these results to real cases, this study provides insights into the chemical variations of fingermark residue and helps clarify the notion of donorship.

Summary: In-source CID and beam-type CID are two methods for mass spectrometry analysis, with the former not requiring an isolation step before collisional activation, resulting in a product ion spectrum composed of fragment ions from any analyte present during the activation event, while the latter involves isolation before collision. The study results show that large fragmentor potentials for in-source CID favor the generation of more abundant lower mass product ions compared to beam-type CID.

Summary: This research investigates the evolution of the secretion residue composition of thirteen donors over one year, focusing on the intravariability, using Matrix-Assisted Laser Desorption/Ionisation Mass Spectrometry Imaging (MALDI-MSI) and chemometrics. Valuable data regarding the evolution of composition over time as well as the consistency of presence of hundreds of compounds were obtained.

Summary: The study of bone mineral density and fracture dating based on healing processes plays a crucial role in forensic anthropology. By emphasizing the importance of these parameters, researchers aim to reconstruct biological profiles, determine time and cause of death, and minimize the impact of medication or substance abuse during life. The introduction of pharmacological history as a correction factor in bone remains analysis, backed by scientific studies, aims to enhance specificity in understanding the effects of certain therapies on bone mass and remodeling speed.

Summary: Data-independent acquisition (DIA) mass spectrometry has become popular due to its reproducibility and quantitative rigor. However, traditional DIA methods may waste instrument time acquiring MS/MS spectra with no usable information. We developed a dynamic DIA strategy that improves quantification sensitivity without sacrificing the number of detected peptides.

Summary: A new method for mycotoxin analysis, DART-Orbitrap MS, was developed and validated in this study, showing rapid, unequivocal, and precise characteristics for monitoring mycotoxins in cereal matrices. A critical comparison with traditional LC-MS methods revealed that DART-Orbitrap MS has advantages in high throughput and rapidity, but falls slightly short in detectability compared to LC-MS.

Summary: This study systematically investigated the influence of host-guest interactions on the analytical performance of direct analysis in real time mass spectrometry (DART-MS) by studying the interactions between cyclodextrins (CDs) and Sudan dyes. The results showed that the host-guest interaction between CDs and Sudan dyes affected the quantitative analysis of the target compounds by lowering the signal intensity. Furthermore, the addition of organic solvents weakened the host-guest interaction and improved the signal intensity in DART-MS, particularly in solid-phase microextraction (SPME).
