16 Operation Manual
2 Operating Basics
Overview
Operating the GC involves the following tasks:
• Setting up the GC hardware for an analytical method.
• Starting up the GC. See “To Start Up the GC”.
• Preparing the automatic liquid sampler. Install the
method- defined syringe; configure solvent and waste
bottle usage and syringe size; and prepare and load
solvent, waste, and sample vials.
• For the 7693A ALS, see its Installation, Operation, and
Maintenance manual.
• For the 7683 ALS, see manual Operating the 7683B
ALS on a 7890 Series GC.
• Loading the analytical method or sequence into the GC
control system.
• See the Agilent data system documentation.
• For standalone GC operation see “To load a method”
and “To load a stored sequence”.
• Running the method or sequence.
• See the Agilent data system documentation.
• For standalone GC operation, see “To manually inject a
sample with a syringe and start a run”, “To run a
method to process a single ALS sample”, and “To start
running a sequence”.
• Monitoring sample runs from the GC control panel or the
Agilent data system program. See “About GC Status” or
the Agilent data system documentation.
• Shutting down the GC. See “To Shut Down the GC for
Less Than a Week” or “To Shut Down the GC for More
Than a Week”.
