The HP / Agilent
1100 series is the current model and arguably the best design in the
industry because of the optimized design of the
quaternary pump ensuring virtually
pulse-free and stable solvent flow, with dual floating pistons in
series, precisely servo-controlled. This design with variable stroke
volume allows pulse-free solvent delivery and efficient mixing. An
inlet-valve electronically activated and synchronized to piston stroke
- eliminates vapor formation with volatile solvents and is maintenance
free. With high-speed proportioning valve and pre-configured vacuum
degasser, for convenient low-pressure mixing of up to four solvents
and highest flexibility in solvent choices.

Pump Features :
Ease-of-use - handheld control
module lets you enter operating parameters fast, store methods easily
and display pressure profile, diagnostics and task-oriented
information.
Durable -
stainless steel, titanium, gold, ruby, sapphire, ceramics, PEEK
and PTFE ensure long lifetime. Seal wash
option for high salt mobile phases keeps maintenance to a minimum for
lower operation costs.
Wide flow range - up to 10
ml/min for broad HPLC work, including semi-preparative
separations.
Better for
GLP - built-in leak and pressure test with graphical presentation
of pressure profiles, and early maintenance feedback.

You can add
spectral acquisition to your HPLC analyses with the Agilent 1100
Series diode array detector. Verify separation quality with peak
purity, multiple signals and spectral libraries - interactively or
automatically in the same run as your analytical quantification.
Extended wavelength range from 190 to 950 nm with highest sensitivity
or spectral resolution with programmable
slit. And holmium oxide wavelength verification for GLP compliance.
The temperature management system ensures optimum baseline
stability–even under rough ambient conditions.
Two lamps in the HP 1100 Series
diodearray detector ensure the highest light output from 190 to 950
nm, for the lowest detection limits over the entire wavelength range.
The use of 1,024 diodes and an optical slit programmable from 1 to 16
nm ensures the best possible spectral bandwidth.
Both the VWD and
diode array detectors use a holmium oxide filter for automated
wavelength verification and for tracking the detector's performance
characteristics. They also employ a new design that allows front
access for the exchange of flow cells and pre-aligned
lamps.
Features:
Access the spectral domain with
superior 3D optics–simultaneous illumination using combined
deuterium and tungsten lamps for highest intensity and lowest
detection limit from 190 to 950 nm, 1024 diodes and 1-nm slit for
highest spectral resolution.
Programmable slit helps you explore the spectral landscape for
faster sample characterization–focus on fine bands with narrow
setting, or if higher sensitivity is required open up the programmable
slit for more light throughput. A broad slit ensures lowest baseline
noise and highest chromatographic signal-to-noise. Store and report
slit settings, from 1 - 16 nm, together with your raw data for GLP
traceability.
Spectral storage and flexible
viewing –easily overlaid spectra within a run or between
runs.
Verify wavelength accuracy for GLP compliance–automatic holmium
oxide filter (which can be set at the beginning of your
chromatography) verifies that your wavelength is indeed what the
setpoint says it is.
