Figure 12-8. Model of total MeOH amount entering the eletrospray ionization probe using a prebackpressure regulator splitter with the sheath pump interface as a function of the ultra-high performance supercritical fluid chromatography mobile phase flow rate (x-axis) and sheath pump flow-rate (y-axis) for two different mobile phase CO2/methanol compositions. (A) composition 95:5, (B) 80:20 and three different fixed back-pressures: 120 bar (A1, B1), 150 bar (A2, B2), and 180 bar (A3, B3). MeOH, methanol; MS, mass spectrometry; SFC, supercritical fluid chromatography.
