Create a technical illustration of a modern UHPLC system: quaternary solvent degasser with vacuum membrane, high-pressure gradient pump (dual-piston with active pulse dampening, up to 1500 bar), autosampler with temperature-controlled sample tray and needle-in-needle injection, column oven compartment with pre-heater and active post-column cooler, sub-2μm C18 column (2.1×100mm, 1.7μm BEH particles), diode array detector (190-800nm, 80Hz acquisition), fluorescence detector, and fraction collector. Show flow path with pressure monitoring points.
