Agilent 1100 HPLC G1376A Cap Pump

The Agilent 1100 HPLC G1376A Cap Pump offers a unique pump technology with a high level of sensitivity and reproducibility for capillary LC. This cap pump features an electronic flow control that measures and controls the actual flow rate, rather than depending on calculations, ensuring stability throughout the analysis. The G1376A also utilizes retention time stability which is independent from column back pressure for maximum performance. Features automatic purge valve, low delay volume, and accurate flow rates.

All of our equipment is fully tested to perform at factory specifications before being shipped.

Agilent 1100 HPLC G1376A Cap Pump Specifications

Hydraulic System

Two dual piston in series, with proprietary servo-controlled variable stroke drive, floating piston, active inlet valve, solvent selection valve and electronic flow control for flow rates up to 100 µl/min

Settable Column Flow Range

0.01 – 20 µl/min

0.01 – 100 µl/min (with the extended flow range kit)

0.001 – 2.5 µl/min (with the electronic flow control bypassed)

Recommended Column Flow Range

1 – 20 µl/min

10 – 100 µl/min (with extended flow range kit)

0.1 – 2.5 ml/min (with the electronic flow sensor bypassed)

Column Flow Precision

< 0.7 % RSD or 0.03 % SD (typically 0.4 % RSD or 0.02 % SD), at 10 µl/min and 50 µl/min column flow (based on RT, default setting)

Optimum Composition Range

1 to 99% or 5 µl/min per channel (primary flow), whatever is greater

Composition Precision

< 0.2 % SD, at 10 µl/min (20 µl flow sensor), 50 µl/min (100 µl flow sensor) and 1 ml/min (normal mode) default setting

Delay Volume

Typically 3 µl from the electronic flow control to the pump outlet for flow rates up to 20 µl/min.

Typically 12 µl from the electronic flow control to the pump outlet for flow rates up to 100 µl.

for flow rates up to 100 µl/min and electronic flow control active: primary flow path 180 - 480 µl without mixer, 600 - 900 µl with mixer (system pressure dependant)

Typically 180 to 480 µl (system pressure dependent) without mixer for flow rates up to 2.5 ml/min. (Mixer delay volume 420 µl)

Pressure Range

20 to 400 bar (5880 psi) system pressure

Compressibility Compensation

User-selectable, based on mobile phase compressibility

Recommended pH Range

1.0 – 8.5, solvents with pH < 2.3 should not contain acids which attack stainless steel. Upper pH range is limited by fused silica capillaries.

Control and Data Evaluation

Agilent ChemStation for LC

Analog Output

For pressure monitoring, 2 mV/bar, one output


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 control module and Agilent ChemStation), leak detection, safe leak handling,

leak output signal for shutdown of pumping system. Low voltages in major maintenance areas.

GLP Features

Early maintenance feedback (EMF) for continuous tracking of instrument 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.


All materials recyclable.
