An intelligent surgical knife (iKnife) coupled with rapid evaporative ionization mass spectrometry (REIMS) was employed for the lipidomic profiling of fresh and frozen–thawed beef muscle. The data were obtained by REIMS then processed using multivariate statistical analysis methods including principal component analysis–linear discriminant (PCA–LDA) orthogonal partial least-squares (OPLS-DA). discrimination meat has been achieved, real-time identification accuracy 92–100%. Changes in...
Abstract The commercially available and cheap sodium dithionite is used as the source of sulfonyl group for synthesis sulfones sulfonamides from (hetero)aryl iodides under catalyst‐free conditions. During reaction process, sulfinates generated in situ are key intermediate, which can be further converted into diverse sulfonamides. This transformation proceeds through a radical process initiated by dithionite, providing convenient route to sulfonyl‐containing compounds. magnified image
In this paper an analytical method based on high performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS) for the determination of coumarin and its derivatives in tobacco products was developed. The MS/MS fragmentation pathways eight coumarins were elucidated. new defined two main axes, extraction procedure with acetonitrile analyte detection performed by HPLC-MS/MS electron impact mode. excellent selectivity sensitivity achieved multiple reaction monitoring (MRM)...
A hollow porous NiMn2O4 nanosphere-decorated cellulose-based carbon fiber (CCF, using recyclable cotton wool as the source) hybrid was fabricated via a relatively green and eco-friendly hydrothermal synthetic route, followed by calcination treatment. The in situ growth of on CCFs led to it being decorated over CCF surface uniformly. NiMn2O4/CCFs displayed excellent extraction capabilities magnetic reusability. Benefiting from its high porosity, large specific area, superior chemical...
Zearalenone has attracted worldwide attention due to its toxic properties and threat public health. A rapid determination method for zearalenone derivatives by hydrophilic covalent organic frameworks coated steel sheet (HCOFCS) combined with ambient mass spectrometry (AMS) was developed. The HCOFCS behaved as both a tip solid-phase microextraction solid substrate electrospray ionization (ESI-MS). To evaluate the HCOFCS-ESI-MS method, five in milk samples were determined, including (ZEA),...
This paper presents an application of high performance liquid chromatography coupled with quadrupole orbitrap high-resolution mass spectrometry (HPLC-Q-Orbitrap HRMS) for the analysis 27 β-blockers and metabolites in milk powder. Homogenized power samples were extracted by acetonitrile purified using Oasis PRiME HLB solid-phase extraction cartridges. The Ascentis® C8 chromatographic column was used to separate analytes. quantification achieved matrix-matched standard calibration curves...
We have described a sulfonamide-selective ambient ion source coupled with electrospray ionization mass spectrometry (ESI-MS) for selective extraction and determination of trace sulfonamide antibiotics. It is obtained by modifying an iron sheet sulfadiazine-templated hydrophilic molecularly imprinted polymer (SF-HMIP). behaves as both online extractor MS source. Five antibiotics, including sulfamethoxazole (SMZ), sulfamerazine (SMR), sulfisoxazole (SIZ), sulfathiazole (ST), sulfameter (SMD),...
Discovering the fungus-infected or mycotoxin-contaminated biomarkers is significant for systems biology since metabolites in biological samples have polarity differences both stochastic gene expression and microenvironmental change. Here, we aim to establish a comprehensive method lipidome by ion mobility mass spectrometry (IMS) merged with chemometrics accurately find out more scientific markers of cell interference mycotoxins pathogenesis exploration drug development. The abundances...
Sorghum is an important grain with a high economic value for liquor production. Tracing the geographical origin of sorghum vital to guarantee flavor. Soldering iron-based rapid evaporative ionization mass spectrometry (REIMS) combined chemometrics was developed real-time discrimination sorghum's origin. The working conditions soldering were optimized, and then obtained MS profiling data processed using analysis methods, including principal component analysis-linear discriminant orthogonal...
