Performance Specifications
Tab le 4 Performance Specification Agilent 1200 Series Quaternary Pump
Type Specification
Hydraulic system Dual plunger in series pump with proprietary servo-controlled variable
stroke drive, floating plungers and active inlet valve
Setable flow range 0.001 – 10 ml/min, in 0.001 ml/min increments
Flow range 0.2 – 10.0 ml/min
Flow precision £ 0.07% RSD, or £ 0.02 min SD whatever is greater, based on retention
time at constant room temperature
Flow accuracy ± 1% or 10 µl/min whatever is greater
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 (10 bar)
Compressibility
compensation
User-selectable, based on mobile phase compressibility
Recommended pH
