The direct analysis of complex organic solid samples, such as coal, still represents a challenge for mass spectrometric researchers. In this work, we present an approach to analyze various carbonaceous samples with different degrees of coalification (one peat and five coals) using laser desorption/ionization in negative ion mode (LDI(−)) and ultrahigh resolving Fourier transform ion cyclotron resonance mass spectrometry. This preparation and analysis method enables a characterization of reactive organic molecules in their native state, without a need for excessive sample preparation or processing. By combining ultrahigh resolving mass spectrometry with different chemometric analyses, an in-depth characterization of the analyzed peat and coal samples was possible, and a correlation between the mass spectra and the degree of coalification of each sample could be verified. As a proof of concept, various analytical standard molecules were analyzed at increasing laser powers to demonstrate that the detected coal-related molecules are actually contained in the samples and were not simply formed by fragmentation reactions during the LDI process. Overall, the direct analysis method presented is a time-saving alternative to analyze complex organic solid samples of all kinds by mass spectrometry.

“…Compared with the traditional small organic matrixes, inorganic nanomaterials own the advantages of low background interference in the low mass range and nonvolatile, which can be used under vacuum conditions. According to the type of nanomaterials, they can be divided into semiconductor-based [50], carbon-based [51], metal-based [52,53], etc. Some inorganic matrixes have been reported have strong affinity to specific substances [54][55][56][57].…”

Mass spectrometry is considered the most informative technique for components identification and has been widely adopted in plant sciences. However, the spatial distribution of compounds in the plant, which is vital for the exploration of plant physiological mechanisms, is missed in MS analysis. In recent years, mass spectrometry imaging has brought a great breakthrough in plant analysis because it can determine both the molecular compositions and spatial distributions, which is conducive to understand functions and regulation pathways of specific components in plants. Mass spectrometry imaging analysis of plant tissue is toward high sensitivity, high spatial resolution, and even single-cell analysis. Despite many challenges and technical barriers, such as difficulties of sample pretreatment caused by morphological diversity of plant tissues, obstacles for high spatial resolution imaging, and so on, lots of researches have contributed to remarkable progress, including improvement in tissue preparation, matrix innovation, and ionization mode development. This review focuses on the advances of mass spectrometry imaging analysis of plants in the last 5 years, including commonly used ionization techniques, technical advances, and recent applications of mass spectrometry imaging in plants.

The detailed composition description of poly(ethylene terephthalate) (PET) pyrolysis products still remains a challenge due to the complexity of the obtained mixture. In this context, Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) analyses by negative ion electrospray ionization (−) ESI and positive ion laser desorption ionization (+) LDI were performed for characterizing waxy products and solid residues, respectively. (−) ESI FT-ICR MS revealed that the DBE of waxy compounds ranges from 5 to 20 and the carbon number from 7 to 30. Terephthalic acid was the dominant peak in the low m/z range, and 1,4-benzenedicarboxylic acid, 1,2-ethanediyl ester was evidence at higher m/z value. Based on the oxygen atom number, the waxy products displayed seven class compounds. The most significant contributions were observed for O4 and O8 species. van Krevelen plots revealed that the most abundant aromatic species followed a monotonous behavior (alignment according to a straight line), highlighting the presence of homologous series. The analysis of the solid residue by (+) LDI FT-ICR MS showed that three classes of compounds were observed: oxygenated compounds, carbonaceous materials, and hydrocarbons. As the temperature increased, the solid residue tended to be associated to a homogeneous structure consisting of fullerene clusters C n (with n ranging from 30 to 96 at 410 °C and from 50 to 106 at 480 °C). C60 was systematically the most abundant fullerene.
