Flow range 0.2 – 10.0 ml/min
Flow precision < 0.3 % RSD (typically 0.15 %), based on retention time, at 1 ml/min
Pressure Operating range 0 – 40 MPa (0 – 400 bar, 0 – 5880 psi) up to 5 ml/min
Operating range 0 – 20 MPa (0 – 200 bar, 0 – 2950 psi) up to 10 ml/min
Pressure pulsation < 2 %amplitude (typically < 1 %), at 1 ml/min isopropanol,
at all pressures > 1 MPa (10bar)
Compressibility
compensation User-selectable, based on mobile phase compressibility
