Web4 jun. 2024 · The HPLC system was coupled to a single MS equipped with an ESI interface operating in positive ion mode using a capillary voltage of 2000 V. The other optimum values of the ESI–MS in positive parameters were drying gas temperature 350 °C, drying gas flow 13 L/min, nebulising gas pressure 40 psi. WebAliquots of the solution were transferred to HPLC vials for analysis by LC-MS/MS. Standards are prepared by diluting mixtures of the eight compound’s working standards into the extraction solvent to final concentrations of 0.1, 0.2, 1.0, 2.0, 5.0, 10 and 20 ng/ml of each analyte prior to mixture and transfer.
