Agilent HP G1376A 1100 Quatpump Quaternary Pump for HPLC - WORKING

Description

Agilent 1100 HPLC G1376A Cap Pump
Pulled from assembly in
Working Condition
and thoroughly cleaned
.
This pump offers a high level of sensitivity and reproducibility for capillary LC.
It also 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
accurate flow rates
Manufacturer’s Specs:
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
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 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
