Specifications - 1200 Series Quaternary Pump 

Flow

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

Range

Setpoints from 0.001 to 10.0 ml/min, in 0.001 ml/min increments

Pressure

Operating range

0 - 40 MPa (0 - 400 bar, 0 - 5880 psi) up to 5 ml/min
0 - 20 MPa (0 - 200 bar, 0 - 2950 psi) up to 10 ml/min

Pulsation

<2 % amplitude (typically <1 %) at 1 mL/min isopropanol at all pressures >1 MPa (> 10 bar, >147 psi)

Compressibility compensation

User selectable, based on mobile phase compressibility

Gradient

Delay volume

800 - 1100 µL depending on back pressure

Pulsation

<0.20 % SD, at 0.2 and 1 mL/min

Recommended pH range

1.0 - 12.5
Solvents with pH <2.3 should not contain acids which attack steel

GLP features

Electronic records of maintenance and errors.
Early maintenance feedback (EMF) for
continuous tracking of instrument usage, display of feedback messages if preset limits are exceeded.
