Agilent 1200 Series G1312A Bin Pump

Type

Specification

Hydraulic system

Two dual piston in series pumps with proprietary servo-controlled variable stroke drive, floating piston design and active inlet valve

Setable flow range

Set points 0.001 – 5 ml/min, in 0.001 ml/min increments

Flow range

0.1 – 5.0 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% of 10µl/min whatever is greater

Pressure

Operating range 0 400 bar (0-5880 psi) up to 5 ml/min

Pressure pulsation

< 2% amplitude (typically < 1%), at 1 ml/min isopropanol, at all pressures > 1 MPa

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

High-pressure binary mixing, delay volume 180-480 µl without mixer, 600 – 900 µl with mixer, dependent on back pressure

Composition range

1 – 99 % or 5 µl/min per channel, whatever is greater

Composition precision

<0.5% absolute

Composition accuracy

0.15% RSD, at 1 ml/min

Control and data evaluation

Agilent Chem Station for LC

Analog output

For pressure monitoring, 2mV/bar, one output

Communications

Controller-area network (CAN), GPIB, RS-232C, APG Remote: ready, start, stop and shut-down signals, LAN optional

Safety and maintenance

Extensive diagnostics, error detection and display (through handheld controllers G4208 A, G1323 B and Agilent Chem Station), leak detection, safe leak handling, leak output signal for shut down of pumping system. Low voltage in major maintenance areas

GLP features

Early maintenance feedback (EMF) for continuous tracking of instruments usage in terms of seal wear and volume of pumped mobile phase with user-settable limits and feedback messages. Electronic records of maintenance and errors.

Housing

All materials recyclable
