Methodology and Instrumentation

The Agilent 1100 Value System employs a modular architecture, interconnected via Controller Area Network (CAN) and managed over a LAN link using a JetDirect card. Core modules include:

• G1310A Isocratic Pump with solvent cabinet and purge valve.
• G1328A Manual Injector featuring a six-port rotary valve and sample loop.
• G1314A Variable Wavelength Detector (VWD) equipped with a 10 mm path-length flow cell.
• 2D-Value Solution ChemStation software running on Windows NT, controlling modules via TCP/IP.

Optional components such as the thermostatted column compartment, fluorescence detector, and refractive index detector may be added to extend functionality. The guide details solvent priming, capillary connections, software setup, and method parameter transfer.

Main Features and Discussion

• System Configuration and Restrictions: Defines permissible module combinations and operating modes under the Value Solution license.
• Site Requirements: Bench space, power specifications (100–120 or 220–240 VAC), environmental tolerances (0–55 °C, non-condensing humidity), and safety considerations.
• Performance Specifications: Physical dimensions, weight, power consumption, and compliance with safety and EMC standards.
• Installation Workflow: Step-by-step instructions for module stacking, LAN setup with Bootp Server, and ChemStation configuration editor.
• Method Setup: Example isocratic analysis of a dimethylphthalate/diethylphthalate/biphenyl/o-terphenyl standard, including flow rate, wavelength, and injection procedure.
• Diagnostic Tools: LED status indicators, analog output signals, online error and status logs, module-specific tests, and troubleshooting guides.
• Maintenance Procedures: Firmware updates via Agilent support portal, deinstallation/reinstallation of software, and full system recovery after OS failure.

Benefits and Practical Applications
