|LDB Lichen Database||
|MS/MS spectra of 241 small molecules isolated from lichens collected in the chemical library of S. Huneck (Berlin Garden and Botanical Museum) provided by Harrie Sipman and Robert Lücking. The spectra were produced by three different LC-MS machines, ie and Agilent 6530 qToF (Pierre Le Pogam, University of Paris-Sud, University of Paris-Saclay, Joel Boustie, University of Rennes 1), a Waters Xevo G2-XS qToF (David Rondeau, Thomas Delhaye, University of Rennes 1) and a Thermo Q-Exactive Orbitrap (Jean-Luc Wolfender, Pierre-Marie Allard, University of Geneva). The LDB currently contains more than a thousand spectra across different machines, including diverse adduct spectra in addition to the [M+/-H]. The most common scaffolds in lichens are represented : depsidones, dibenzofuranes, pulvinic acids, paraconic acids, chromones, quinones, xanthones, monoaromatic compounds, quinones, xanthones and chromones. These spectra are not single energy but the consensus of spectra produced at different energies. For Agilent, these were 10, 25 and 40 eV in ESI-, (and also 2.5, 5.0 and 7.5 eV for the more fragile depsides), and 5, 20 and 35 eV in ESI+ or APCI+ for terpenes. For Waters, the collision energies were 10, 20, 30 and 40 eV in ESI- and ESI+. The Thermo spectra were acquired using Normalized Collision Energy (NCE) based on the measured m/z value and three energies : 15, 30, 45 eV.|

|Nutri-Metabolomics||View Positive View Negative||
This library is made with Orbitrap LTQ-XL mass spectrometer. Scan for full scan was of 30,000 while, MSMS were acquired at 7500 resolution. The CID of 35 eV was applied. References for operational conditions of Orbitrap and LC columns are here: DOI 10.1007/s11306-015-0935-z and DOI: 10.1002/mnfr.201901137.
This library consists of different analytical standards which were purchased form Sigma Aldrich for Fondazione Edmund Mach (Italy), for Nutri-metabolomics research.
Compounds that are included in this library are: small phenolic acids, organic acids, fatty acids, carnitines, indoles, some aroma compounds, endogenous human metabolites. They were purchased for two purposes: i) the confirmation at level I of some metabolites, ii) look for matching substructures between biomarkers in studies and analytical standards.
|GNPS Sciex Library||View||The Sciex dataset contains authentic standards from different compound libraries and single reference standards were used. Specifically, the Agilent LC/MS Pesticide Comprehensive mix, Sigma Aldrich Bile Acid/Carnitine/Sterol Metabolite Library of Standards, Sigma Aldrich Fatty Acid Metabolite Library of Standards and Sigma Aldrich Acid Metabolite Library of Standards were used. Standards were dissolved in suitable solvents and mixed in 43 mixtures in such way to avoid overlap of isomeric and isobaric substances. Standard mixtures were analyzed using a Sciex Exion AD liquid chromatography system coupled to a Sciex X500R QTOF-MS. Separation was achieved on a Phenomenex Kinetex F5 column (150 mm × 2.1 mm ID, 2.6 μm particle size) with a gradient from eluent A (100 % H 2 O + 0.1 % formic acid) to eluent B (100 % acetonitrile + 0.1 % formic acid) using the following gradient: 100/0 at 0 min, 100/0 at 2.1 min, 5/95 at 14 min, 5/95 at 16 min, 100/0 at 16.1 min, and 100/0 at 20 min. Column temperature was set to 30 ◦ C and flow rate to 200 μL/min. Data was acquired by data dependent acquisition of MS/MS spectra using a collision energy ramp from 20 to 50 eV. The MS was automatically recalibrated every five injections in MS1 and MS/MS mode.|
