The mass spectrometry data for Rivularia sp. cyanobacteria were deposited at MassIVE (accession no. MSV000085578). The spectra for rivulariapeptolide 1155 were annotated in the GNPS spectral.
Computational mass spectrometry
Coldspray ionization (CSI) mass spectrometry, a variant of electrospray ionization (ESI) operating at low temperature (20 to −80. °C), has been used to characterize protein conformation and noncovalent complexes.. A comparison of CSI and ESI was presented for the investigation of the equilibrium acid-induced unfolding of cytochrome c, ubiquitin, myoglobin, and cyclophilin A (CypA) over a.

Figure 6.3.2 6.3. 2: Diagram of Electrospray Ionization (Banerjee & Mazumdar, 2012) The electric field also directs the spray toward the mass spectrometer while droplets diminish in size (solvent evaporation) 1. This process is described pictorally in Figure 6.3.3 6.3. 3 below. Once the electrospray droplets pass through the heating capillary.

The mixture solutions were infused into the Q Exactive hybrid quadrupole-Orbitrap mass spectrometer via the custom CSI device at a flow rate of 10 μL/min. Results demonstrated that the glycyrrhizic acid/aconitine self-assembled complex was observed in the positive ion mode with a binding ratio of 1:1 ([glycyrrhizic acid/aconitine+H] +) at m/z.

The goal of this study was to explore the use of LC-captive spray ionization (CSI)-mass spectrometry for detection, characterization and quantification of drugs and metabolites. CSI allows the use of conventional HPLC or uHPLC columns and flow rates of 0.35-0.6 mL/min (before post-column flow splitting) and can be considered as a technique.

Cold spray ionization mass spectrometry (CSI-MS) is a variant of ESI-MS that promotes ionization by increasing the polarizability of the compound at low temperature [17]. This native-MS technique allows the facile and precise characterization of weak noncovalent interactions in solutions compared to the conventional ESI method [18].

Mass Spectrometry Professor Dave Explains
Coldspray ionization (CSI) mass spectrometry (MS) has been developed and applied to characterize labile organometallic compounds. While conventional ESI is not applicable to those compounds because of their instability to heat and/or air, CSI affords multiply charged molecular ions with many solvents molecules attached. Here we describe the CSI method and its application to several labile.

A simple method for measuring CsI cluster ions ((CsI) n Cs + and (CsI) n I −) from CsI 3 for mass calibration was developed using matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). The application of CsI 3 with an additive, sugar alcohol (e.g., glycerol) or saccharide (e.g., dihydroxyacetone), on the MALDI plate resulted in an adequate series of CsI cluster ions within.
