Consider the following information and guidelines for operation of the system.

For Best Performance

  • Wash the inside and outside of the needle to reduce carry-over. The needle wash ensures that the needle is properly cleaned from any remaining sample.

  • Keep the column compartment door closed during operation.

  • Avoid switching any valves dry, that is, without pump flow. This may damage the valve.

  • Do not operate the pump with a dry seal wash system.

  • Observe the general guidelines and recommendations on the use of solvents and additives in the system. See Solvent and Additive Information.

Notes on Sample Processing

Note the following when operating the autosampler:

TIP

Keep the Autosampler Doors Closed During Sample Processing

  • If the doors are opened during needle and carousel movement, the autosampler stops the current movement of the needle arm. The needle does not puncture the sample container and does not draw sample. An acoustic signal alerts you that the doors are open.
  • Every time the doors are closed, the autosampler performs an inventory scan of the sample racks and sample containers in the sample compartment.
