Preventive maintenance
This section contains some suggestions for ensuring good performance. The
maintenance interval varies with the use of the instrument.
Caution Do not use any lubricants on the automatic liquid sampler. They may affect the
chemical performance of the GC and damage the instruments.
For instructions on the proper use and replacement of consumable parts, such
as septa, inlet liners, syringes, and sample vials, see chapter 3, “Operation.” For
instructions on aligning the brackets, see the bracket installation guides.
Regular basis (before you start a sequence
• Get a new or clean syringe rinsed with solvent.
• Be sure the plunger carrier holds the plunger button.
• Measure 4.5 ml of fresh solvent in each solvent bottle.
• Be sure the waste bottles are clean and empty.
• Be sure the number of sample vials does not exceed solvent capacity.
• Place the sample vials correctly according to the controlling device.
• Cap the sample vials properly.
Note: The inlet does not require maintenance.
