Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

The scent of death: A case study for volatile markers of decomposition on a concrete floor

Journal of Forensic Sciences, EarlyView.
Abstract Volatile organic compounds (VOCs) released during human decomposition are chemically diverse and can provide forensic evidence indicating the prior presence of a corpse. In July 2023, the Michigan City Police Department received a report from an individual claiming to have murdered his roommate and stored the body in a basement cellar for 57 ...

An Easy Method to Sample Headspace Pheromones in the Field

Ethology, EarlyView.
Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.

Development of a Direct Headspace Collection Method from Arabidopsis Seedlings Using HS-SPME-GC-TOF-MS Analysis

Metabolites, 2013
Plants produce various volatile organic compounds (VOCs), which are thought to be a crucial factor in their interactions with harmful insects, plants and animals. Composition of VOCs may differ when plants are grown under different nutrient conditions, i.

Chromosome‐Scale Haplotype Genome Assemblies for the Australian Mango ‘Kensington Pride’ and a Wild Relative, Mangifera laurina, Provide Insights Into Anthracnose‐Resistance and Volatile Compound Biosynthesis Genes

Plant Biotechnology Journal, EarlyView.
ABSTRACT Mango (Mangifera indica) is one of the most popular fruits cultivated in tropical and subtropical regions of the world. The availability of reference genomes helps to identify the genetic basis of important traits. Here, we report assembled high‐quality chromosome‐level genomes for the Australian mango cultivar ‘Kensington Pride’ and M ...

From freshness to preservation: insights into processing and storage impacts on purple passion fruit volatilome

Journal of the Science of Food and Agriculture, Volume 106, Issue 4, Page 2139-2153, 15 March 2026.
Abstract BACKGROUND Purple passion fruit is highly appreciated for its distinctive sweet flavour, low acidity, and aromatic profile, making it a desirable choice for fresh consumption and juice production. To ensure microbiological safety and extend shelf life, juice products typically undergo thermal pasteurization, which can alter their ...
