Studies published over the last five years have focused on fully or semi-automated approaches and their applications in extraction of both organic and inorganic pollutants, while modern robotic tools and 3D printing are starting to make impacts.

As researchers demonstrated in a second recent report, their devised method was effective for identification of cocaine, but there is no consensus as to a “best” algorithm for all necessary scenarios.

Since similar chiral recognition mechanisms were observed for benzoin (B) and methyl mandelate (MM), a three-site enantioselectivity model was proposed to interpret the data being sought by researchers.

Microfluidic devices are considered ideal for fabricating portable diagnostic equipment for point-of-care testing, but substrates more environmentally friendly than glass or plastics are attracting interest.

In this interview, Hroncich talks with editor Patrick Lavery about her experience and what readers can expect for the future.

While mass spectrometry (MS) is the favored analytical technique for the primary structures of proteins and their post-translational modifications (PTMs), the combinatorial isomers that commonly co-occur necessitate a more advanced approach.

Increases and decreases in anthocyanin concentration, which relates to the level of sugars found in red wine, were observed at specific weekly intervals of the grape ripening process.

Five prior winners of our annual Emerging Leader Award give their perspectives on how to thrive and find success in the separation science field.

A new report from Meticulous Research attributes the growth to the development of antibody-based therapeutics and biosimilars.

Plant growth regulators (PGRs) have significant effects on plant physiological processes, but the complex matrices of plants, along with polarity and instability issues inherent with PGRs, complicate trace analysis of these compounds.

Sauce-flavor or sauce-aroma baijiu, one variant of a popular Chinese liquor, is treated with a fermentation starter called daqu, giving the concoction a unique taste profile, and scientists want more information about how it can inform the manufacturing of higher-quality baijiu.

In a presentation at NACRW 2023, Yelena Sapozhnikova of the U.S. Department of Agriculture (USDA) explained that even though levels of per- and polyfluoroalkyl substances (PFAS) were found in everything from tomato packaging to cake paper in global samples, values were below the European Food Safety Authority (EFSA)’s maximum tolerable weekly intake (TWI).

Bjorn Berendsen of Wageningen University & Research said at NACRW 2023 that among more than 6,000 suspected per- and polyfluoroalkyl substances (PFAS), detailed information is known about relatively few.

Among the compounds of concern found in the samples were nicotine-related alkaloids, psychoactive cannabinoids, and chemicals that promoted inflammation of the respiratory system.

While both branched-chain fatty acids (BCFAs) and straight-chain fatty acids (SCFAs) were analyzed, the profiling of BCFAs was considered especially important for future metabolomics and lipidomics studies.

High-throughput proteomic research has been hampered by the limited peak capacity of one-dimensional liquid chromatography (1D-LC) separation performance.

The two-dimensional liquid chromatography (2D-LC) separations were supplemented by the use of capillary-channeled polymer (C-CP) fiber columns.

Photoionization detectors (PIDs) are attractive for their high sensitivity and fast response time, while cost-effective equipment has been sought for online monitoring of volatile organic compounds (VOCs).

A water-resistant, highly adsorptive molecularly imprinted polymer was developed to address the issues of unstable adsorption performance and high organic solvent consumption in traditional materials.

Authentication of popular ginseng-based products has been difficult and has caused confusion in quality control between traditional Chinese medicine (TCM) and Chinese patent medicine (CPM).

Quality control of raw hazelnuts is already a highly specific process, but has limitations including operator influence, duration, and lack of standardization. AI is now assisting in quality decision-making using GC×GC analysis.

Although closantel (CLO) is well-regarded as a curative antiparasitic drug, even low doses have been found to cause serious side effects in the human retina and central nervous system.

Stephanie Rankin-Turner and colleagues at Johns Hopkins Bloomberg School of Public Health have recently performed research in Zambia indicating that mosquitoes are more attracted to humans who exhibit abundant levels of certain volatile carboxylic acids.

While most diapers do not contain all 15 polycyclic aromatic hydrocarbons (PAHs), the concentration of these compounds varies by manufacturer, and no disposable diaper is entirely free of PAHs.

The combination of deep eutectic solvents (DESs) and cellulose paper, according to the researchers, bridges a current gap in sustainable, paper-based sorptive phases.

Nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) are suspected to be carcinogenic, and improvements are sought to improve gas chromatography–mass spectrometry (GC–MS) methods traditionally used for this analysis.

A novel isotopologue was synthesized in a stable isotope dilution assay (SIDA) for quantification of γ-nonalactone for the first time in pinot noir wines from New Zealand.

Enhancements in chromatographic performance were reviewed as were experimental concerns, both pointing toward using specific solvents to influence more sustainable industrial development.

LCGC and Spectroscopy magazines recently welcomed Caroline Hroncich to lead their joint editorial staff in print and online. In this interview, Hroncich talks with editor Patrick Lavery about her experience and what readers can expect for the future.

Levoglucosan, which is emitted from the combustion of cellulose and hemicelluloses, can be transported over a long range of time to ice caps, where it may indicate fire activity both regionally and globally.
