The detailed MS parameters were as follows: the ion source parameter had a spray voltage of 1.9 kV and a capillary temperature of 270 °C, with FAIMS compensation voltage set to −48 V. For Orbitrap MS full scans, the resolution was 240,000, the normalized AGC target was 500%...
The feed solution was introduced, along with the dehumidified drying air through a three-fluid nozzle system mounted on top of the spray drier, the inlet air drying temperature was set at 120 °C, and the debit of the peristaltic pump was set at 10% (3 mL/min). The debit flow meter...
The freeze-dried samples were dissolved in 0.02 mol/L NH4HCO3, and the supernatant after centrifugation (4000 rpm, 10 min) was purified by Bio-Gel P4 chromatography eluting with 0.02 mol/L NH4HCO3 at a flow rate of 3.0 mL/h. The components collected by the automatic collector were desalted...
(UMAE) is performed. Prior to extraction, a drying step of the pulps is conducted using freeze, vacuum and hot air drying. Except for the conventional extraction solvents of water and ethanol:water, a deep eutectic solvent (DES) formed by choline chloride/urea, and a natural deep eutectic ...
A; 17.1–20 min, 80% A, stop. For the MS detection, the positive and negative ions of electron spray ionization (ESI) were simultaneously scanned. Other parameters of the mass spectrometer were as follows: ion source temperature of 400 °C, flow rate of atomizing gas of 1.5 mL/min, ...
HPLC separation was carried out on a C18-column (Aqua 3u, 100 Å, 3 μm, 150 mm × 2.0 mm i.d.) from Phenomenex (Aschaffenburg, Germany) with a guard column of the same material at a flow rate of 0.20 mL/min. The mobile phase consisted of 2% aqueous acetic acid (v/v) (A)...
In the case of large animals, small pieces of tissue are sufficient for DNA studies (precooled 96% ethanol, ´80˝ freezing or freeze of tissues using liquid nitrogen) so that the specimen can be used for museum collections. Fixation of large megabenthos is done in a minimum of 4% ...
