Smart detection of juice adulteration: An approach based on ion mobility spectrometry and machine learning

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Fruit juice quality is regulated by European Union legislation; however, adulteration by adding cheaper alternatives, such as white grape juice, remains a prevalent issue. This practice constitutes economic fraud and poses health risks to consumers, including potential allergic reactions to the adulterant.

FluoroMatch IM: An Interactive Software for PFAS Analysis by Ion Mobility Spectrometry

Environmental Science & Technology
Per- and polyfluoroalkyl substances (PFASs) are often present in complex mixtures at trace levels in environmental samples, posing difficulties for analytical chemists. Ion mobility offers highly replicable identifiers, enabling the use of community-based libraries for PFAS annotation in nontargeted analysis.

Combining Laser‐Induced Edition to Collision‐Induced Sequencing of Digital Oligomers in a Single Gas‐Phase Experiment

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale To increase the confidentiality level of molecular tags, binary information can be hidden in sequence‐defined oligomers using isobaric monomers including a photo‐sensitive one, which mass can be modified upon light irradiation. Reading such secured data requires light edition prior to MS/MS sequencing, which was investigated here in ...

Deciphering Branched Galactomannan Structures via Multistage Ion Mobility MS and MSn Fragmentation (Multistage IMSn)

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Hemicelluloses are abundant carbohydrate components in plant cell walls. They play a crucial structural role in binding cellulose microfibrils, in addition to other biological functions. Their high structural variability directly influences their biological properties, making it important to establish a structure–function ...
