Well Used Hewlett Packard GC ***0 Plus. G***0A. SSL-Injector. FID. Autosampler.HP Compaq ***0. Software from CD.
Chromatographic Performance*
• Retention time repeatability
<0.**8% or <0.***8 min
• Area repeatability
<1%RSD
The Agilent ***0N is a state-of-theart gas chromatograph that
provides superior performance for all applications. Key to its
performance is the use of advanced electronic pneumatic control
(EPC) modules and high performance temperature control. Each EPC
unit is optimized for its intended use with a specific inlet and
detector option. Temperature control of the ***0N oven allows for
fast and precise temperature ramping. Overall thermal performance
provides optimal chromatography including peak symmetry,
retention time repeatability, and retention index accuracy. The
combination of precise pneumatic control and accurate temperature
control leads to outstanding retention time repeatability, the
basis for all chromatographic measurement.
A full array of traditional gas sampling and column switching
valves are available. A new highperformance inert pneumatic
switching manifold is available for a number of advanced
chromatographic applications (*-D heart cutting, detector
splitting, etc). Agilent GC systems are known for their
reliability, ruggedness, and long life. The Agilent **-year use
guarantee provides greater assurance for a low-cost of ownership
throughout its life.
System Capabilities
• Dual channel design supports two inlets and two detectors.
• Full range digital data output enables the smallest and largest
peaks to be quantitated in a single run.
• Full EPC is available for all inlets and detectors. Control
range and resolution are optimized for the specific inlet or
detector module.
• EPC with capillary columns provides four column flow control
modes: constant pressure, ramped pressure (3 ramps), constant
flow, or ramped flow (3 ramps). Column average linear velocity is
calculated.
• Atmospheric pressure and temperature compensation is standard,
so results do not change, even when the laboratory environment
does.
• Automatic Liquid Sampling is fully integrated into mainframe
control.
• Set point and automation control can be done from the local
keyboard or via a networked data system. Clock-time programming
can be initiated from the front panel to initiate events (on/off,
method start, etc) at a future date and time.
• A run time deviation log is created for each analysis to ensure
that all method parameters were achieved and maintained.
• Display of all GC and automatic liquid sampler (ALS) set points
at the GC or data system. Agilent supports open connectivity by
providing communication
protocols to other vendors.
