“…Clusters of monoisotopic elements provide simple spectra with many monoisotopic peaks covering the mass range of interest with regular mass spacing. In this work, we discuss the calibration of mass spectra by clusters of red phosphorus, which is already established in our laboratory [6,[10][11][12][13][14][15][16], and compare it with calibration by gold clusters generated directly on the target by laser desorption ionization (LDI)-MS of various materials, including gold foil [17], various types of gold nanoparticles (AuNPs), chloroauric acid (HAuCl 4 ), a mixture of 2-(4-hydroxyphenylazo) benzoic acid and HAuCl 4 [18], and polyvinylpyrrolidone-stabilized AuNPs [19]. Gold clusters provide simple and fast determination of accurate mass compared with common calibration standards, such as peptides or proteins.…”

Abstract. Precise calibration in TOF MS requires suitable and reliable standards, which are not always available for high masses. We evaluated inorganic clusters of the monoisotopic elements gold and phosphorus (Au n + /Au n -and P n + /P n -) as an alternative to peptides or proteins for the external and internal calibration of mass spectra in various experimental and instrumental scenarios. Monoisotopic gold or phosphorus clusters can be easily generated in situ from suitable precursors by laser desorption/ionization (LDI) or matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). Their use offers numerous advantages, including simplicity of preparation, biological inertness, and exact mass determination even at lower mass resolution. We used citrate-stabilized gold nanoparticles to generate gold calibration clusters, and red phosphorus powder to generate phosphorus clusters. Both elements can be added to samples to perform internal calibration up to mass-to-charge (m/z) 10-15,000 without significantly interfering with the analyte. We demonstrated the use of the gold and phosphorous clusters in the MS analysis of complex biological samples, including microbial standards and total extracts of mouse embryonic fibroblasts. We believe that clusters of monoisotopic elements could be used as generally applicable calibrants for complex biological samples.

Rationale Carbon–phosphides are new and promising strategic materials with applications e.g. in optoelectronics. However, their chemistry and methods of synthesis are not completely understood, and only a limited number of C–P clusters have been detected up to now. Laser ablation synthesis (LAS) or laser desorption ionisation (LDI) has great potential to generate CmPn clusters in the gas phase and to act as the basis for the development of new technology. Methods The LAS of carbon phosphides using mixtures of nano‐carbon sources (graphene, nanodiamonds) with phosphorus allotropes (red, black, and phosphorene) was examined. Since phosphorene is not commercially available, it was synthesised. A reflectron time‐of‐flight mass spectrometer was used to produce and identify the C–P clusters. A transmission electron microscope was used to characterise the prepared composites. Results LDI of various carbon–phosphorus composites generated a range of carbon–phosphides. From graphene–red phosphorus, CmP+ (m = 3–47), CmP2+ (m = 2–44), CmP3+ (m = 1–42), CmP4+ (m = 1–39), CmP5+ (m = 1–37), CmP6+ (m = 1–34), CmP7+ (m = 1–31), CmP8+ (m = 1–29), CmP9+ (m = 1–26), CmP10+ (m = 1–24), CmP11+ (m = 1–21), and CmP12+ (m = 1–19) clusters were detected, while nanodiamond composites with red/black phosphorus and with phosphorene yielded C24P5 + 2n+ (n = 0–28), C24P5 + 2n+ (n = 0–16), and C24P5 + 2n+ (n = 0–14) clusters, respectively. In total, over 300 new carbon–phosphide clusters were generated. Conclusions The novel series of carbon–phosphide clusters generated from graphene or nanodiamond composites with red/black phosphorus or with phosphorene demonstrated rich carbon–phosphide chemistry that might inspire the development of novel nano‐materials with specific properties.

Abstract: TOF MS was shown to be a useful technique for following the formation of gold carbides in the gas phase. Clusters and 'gold-doped' diamonds generated might inspire synthesis of new Au-C materials with hardly predictable, unusual properties.
