The elucidation of structural motifs in extremely complex mixtures is very difficult since the standard methods for are not capable to provide significant information on a single molecule. best method analysis ultrahigh resolution mass spectrometry, but utilization this alone does about details. Here, combination with separation necessary. While chromatography well-established technique, it has some disadvantages regard mixtures, as often no individual isomers possible. Therefore, here an ion mobility spectrometry evaluated. As sample matrix, crude oil used because excellent matrix develop new analytical techniques samples. Crude most natural known, only little available identity or functionalities due high number isobars. A lab-built APPI/APLI-FAIMS source was revised optimize transmission and follow up constituents after photoionization. An MS/MS approach using collision-induced dissociation (CID) elucidate transmitted isomers.

Accurately assigning formulas to thousands of peaks generated by ultrahigh resolution mass spectrometry in a single analysis poses significant challenge, especially when dealing with diverse molecular compositions across complex mixtures. This difficulty is further compounded the lack an established universal calibration and formula assignment method. We have developed HRMS-Viewer, Python-based software tool designed for processing data specific petroleum natural organic matter (NOM). The employs efficient, experience-driven approach small molecule assignment, offering streamlined yet intuitive workflow. Key features include advanced noise reduction, automatic or manual recalibration, real-time visualization results, options correction.

In recent years, various alternatives to fossil fuels have been developed. One of them involves the production bio-oils from lignocellulosic-based biomass through pyrolysis. However, present numerous heteroatoms and, in particular, oxygen atoms that need be removed by an upgrading process. To optimize these processes, it is necessary good knowledge composition at molecular level. This work aims establish usefulness laser desorption ionization (LDI) and matrix-assisted desorption/ionization (MALDI) techniques on lignocellulosic biomass-based bio-oils. Using a Fourier transform ion cyclotron mass spectrometer (FTICR MS), we showed MALDI gives more information than LDI. The selectivity series matrices was investigated, showing some are selective toward compound families others ionize wider range compounds. this study, nine proton-transfer three electron-transfer were used compared results obtained Dithranol, acetosyringone, graphene oxide promising selected all matrices, giving overall characterization oxygenated classes bio-oil. They allowed many species covering wide polarity, aromaticity, with homogeneous relative intensity for such as lignin-derivative species, sugars, lipid-derivative species.

Modern research faces increasingly complex materials with a constant need for new analytical strategies that can provide deeper levels of chemical insight. Ultrahigh resolution mass spectrometry (MS), particularly Fourier transform ion cyclotron resonance (FTICR) MS, has provided robust foundation. However, MS alone offers limited structural information. Here, we present the first implementation and results from an FTICR fully integrated dual accumulation analysis gated trapped mobility (gTIMS) capability. The drastically extended charge capacity parallel facilitate mixtures. We achieved high dynamic range 4 orders magnitude within single acquisition event. Simultaneously, valuable linear relationship between TIMS elution voltage reduced was retained over wide range. Benchmarking instrument performance Suwannee River fulvic acid (SRFA) by variable ramp gTIMS allowed separation unambiguous assignment different state distributions. Application to bio-oils proven capability distinguish isomeric diversity in these ultracomplex samples, while maintaining expected resolving power accuracy. Valuable information about molecular distribution, diversity, main differences could directly be extracted time classical "dilute shoot" direct infusion experiment. development this flexible possesses potential significantly change current landscape high-resolution spectrometric mixtures through added insight complexity afforded TIMS. exploration IMS dimension promises transformative effects across diverse fields including energy transition, environmental studies, biological research.

Bio-oils are a renewable alternative resource for the production of fine chemicals and fuels. characterised by high content oxygenated compounds with diverse array different chemical functionalities. Here, we performed reaction to transform hydroxyl group various components in bio-oil prior characterisation ultrahigh resolution mass spectrometry (UHRMS). The derivatisations were first evaluated using twenty lignin-representative standards structural features. Our results indicate highly chemoselective transformation despite presence other functional groups. Mono- di-acetate products observed acetone-acetic anhydride (acetone-Ac2O) mixtures non-sterically hindered phenols, catechols benzene diols. Dimethyl sulfoxide-Ac2O (DMSO-Ac2O) reactions favoured oxidation primary secondary alcohols formation methylthiomethyl (MTM) phenols. then complex sample gain insights into profile bio-oil. that before derivatisation is composed 4500 elemental compositions containing 1-12 oxygen atoms. After DMSO-Ac2O mixtures, total number increased approximately five-fold. was indicative variety profiles within particular phenols ortho para substituted, non-hindered (about 34%), aromatic (including benzylic non-phenolic alcohols) (25%), aliphatic (6.3%) could be inferred. Phenolic known as coke precursors catalytic pyrolysis upgrading processes. Thus, combination conjunction UHRMS can valuable outline mixtures.

Bio-oils contain a substantial number of highly oxygenated hydrocarbons, which often exhibit low thermal stability during storage, handling, and refining. The primary objectives this study are to characterize the hydroxyl group in bio-oil fractions investigate relationship between type accelerated aging behavior. A was fractionated into five solubility-based fractions, classified two main groups: water-soluble water-insoluble fractions. These were then subjected chemoselective reactions tag molecules containing groups analyzed by negative-ion electrospray ionization 21 T Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). also experiments characterized FT-ICR MS bulk viscosity measurements. Extracting insightful information from ultrahigh-resolution data aid predicting upgrading methodologies instability behaviors bio-oils is challenging due complexity data. To address this, an unsupervised learning technique, k-means clustering analysis, used semiquantify molecular compositions with close Euclidean distance within (O/C, H/C) chemical space. combination analysis findings allowed distinctive functionalities across samples be inferred. Our results indicate that hexane-soluble fraction contained numerous secondary alcohols, while displayed diverse compounds, clustered near carbohydrate-like pyrolytic humin-like materials. Despite its high oxygen content, showed minimal changes aging. In contrast, significant increase observed materials, specifically, low- high-molecular-weight lignin (LMWL HMWL, respectively). Among these HMWL exhibited highest after only 4 h behavior attributed increased phenolic groups. Thus, major contributors under conditions. This highlights crucial role functionality aging, suggesting content alone does not necessarily correlate viscosity. Unlike other categorization methods based on constrained molecule locations van Krevelen compositional space, can identify patterns inherent unique fingerprint each sample.
