Pressure (5 – 10 ml/min) 0 – 20 MPa (0 – 200 bar, 0 – 2950 psi)
Pressure pulsation < 2 % amplitude (typically < 1 %), at 1 ml/min isopropanol, at all pressures > 1 MPa (10 bar)
Compressibility compensation User-selectable, based on mobile phase compressibility
Recommended pH range 1.0 – 12.5; solvents with pH > 2.3 should not contain acids which attack stainless steel
Gradient formation Low pressure quaternary mixing/gradient capability using proprietary high-speed proportioning valve
Delay volume 800 – 1100 µl, dependent on back pressure
Composition range 0 – 95 % or 5 – 100 %, user selectable
Composition precision < 0.2 % SD, at 0.2 and 1 ml/min
