The 2026 release expands coverage of emerging novel psychoactive substances, including synthetic cannabinoids, fentanyl analogs, and pharmaceutical drugs. The database provides comprehensive and up-to-date support for forensic, toxicology, and drug surveillance workflows.
Wiley has expanded its spectral libraries with major updates to IR, Raman, and LC-MS collections, delivering researchers enhanced capabilities for faster and more confident compound identification. The expansion brings over 9.5 million high-quality spectra, including 1 million IR spectra and 161,000 Raman spectra.
Researchers have pinpointed the emergence of muddy flavors in farmed fish by measuring the concentration of geosmin and other compounds. The study highlights the importance of water quality management to prevent the production of off-flavor compounds, which can impact aquaculture industry revenue and sustainability.
Researchers at North Carolina State University identified a specific blend of pheromone chemicals used by male moths during courtship, including an aphrodisiac called methyl salicylate. Female moths can recognize this chemical through two smell receptors, and its presence in males' hairpencils is linked to mating success.
Researchers created a detailed analysis of the domestic cat's nasal airway, revealing two distinct regions of air flow during inhalation. The study suggests that the cat nose functions as an efficient dual-purposed gas chromatograph, capable of detecting and separating chemicals quickly and efficiently.
A new computer simulation suggests that domestic cats' noses function similarly to parallel coiled gas chromatographs, enabling efficient odor detection. This finding deepens understanding of how the evolution of convoluted channels enabled mammals' enhanced sense of smell.
Researchers developed a colorimetric method to detect volatile organic compounds at low levels using a printable glass-based detector. Additionally, strategies are outlined to overcome the single-molecule concentration barrier in fluorescence detection, enabling observations in high-concentration environments. An electrochemical test f...
Researchers at Zurich University of Applied Sciences identified six compounds contributing to fermented coffee's unique flavor, including 2-methylpropanal, 3-methylbutanal, and ethyl 3-methylbutanoate. The study aims to standardize production methods and increase availability of this distinctive beverage.
A new law restricts 1,4-dioxane levels in household cleaners and cosmetics, a potential human carcinogen common in everyday products. Experts recommend robust analytical methods for detection and quantification to meet regulatory requirements.
Scientists from the University of Johannesburg identified ten times more volatile signal compounds from the bacteria, boosting plant growth and protection. Rhizobacteria can protect crops from abiotic and biotic stresses by producing valuable VOCs that trigger Induced Systemic Resistance (ISR) in plants.
Researchers at University of California - Riverside discovered a chemical cocktail in human skin that summons disease-spreading mosquitoes. The combination of carbon dioxide plus two chemicals, 2-ketoglutaric and lactic acids, elicits a scent that attracts female Aedes aegypti mosquitoes, vectors of Zika and other viruses.
Scientists have developed a sustainable method to create valuable aroma compound mixtures from limonene, the main compound in orange peel oil. The process generates an amber-colored liquid with a pleasant odor and 17 different compounds with fruity, herbal, citrus, and resinous notes.
A team of scientists has discovered the molecular triggers of parosmia, a distorted sense of smell, and identified compounds responsible for triggering the sense of disgust. The study found that certain highly potent odor molecules in coffee can lead to this experience.
Researchers analyzed 8 popular plant-based burgers and found that some closely mimic the odor of real beef when cooking. The Beyond Burger from Beyond Meat came closest to replicating the hamburger aroma, but still differed significantly.
Researchers at the University of Copenhagen have developed a new method for analyzing gas chromatographic data using deep learning, allowing for faster and more accurate results. This technology has the potential to improve food quality control, detect food fraud, and enhance patient care by analyzing blood samples.
Chemists at the University of Texas at Arlington have developed a new method to quantify water content in solid pharmaceutical drugs, which is faster, cheaper, and more accurate than Karl Fischer titration. The new method uses headspace gas chromatography with ionic liquids and can analyze samples in just 10 minutes.
Researchers have developed a credit-card-sized gas chromatography platform that can analyze volatile compounds within seconds. The hybrid integrated approach allows for individual components to be miniaturized on separately fabricated chips, increasing the system's portability and throughput.
Researchers at UT Arlington have developed a new method for measuring water content in pharmaceuticals that is up to 100 times more sensitive than current methods. The new technique uses headspace gas chromatography and an ionic liquid column, offering improvements in sensitivity, accuracy, and sample size requirements.
A credit-card-sized gas chromatography platform is being developed to analyze volatile compounds in seconds, enabling faster diagnosis and monitoring of diseases like diabetes and breast cancer. The new architecture, named GC Matrix, will separate complex compounds using MEMS technology, improving speed, portability, and power efficiency.
