LC–MS analyses were performed by an Ultimate 3000 UHPLC instrument coupled with an ISQ EC mass spectrometer, equipped with an electrospray ion source and a single-quadrupole analyzer (Thermo Fisher Scientific, Cambridge, MA, USA). A C18, Luna® Phenomenex, 5 µm 100 Å (150 × 4.6 mm) (Phenomenex, Torrence, CA, USA) was used for chromatographic separation. The mobile phase was composed of solvents A (Water, 0.1% HCOOH) and B (Acetonitrile, 0.1% HCOOH). An isocratic mode (30:70) was used. The flow rate was set at 0.2 mL/min and the column was maintained at 30 °C for the entire run. Fifty microliters were injected. Analyses were performed using the positive ionization mode selecting the following m/z: 91, 137, 154, 369. The collision energy (CE) was 20 eV. Mass spectrometry parameters were: spray voltage (V) 3000, sheet gas (arb) 28.8 psig, aux gas (arb) 3.2 psig, ion transfer tube temperature 300 °C, and vaporizer temp 117 °C.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
