Follow these guidelines:

  • Always wear a new pair of lint- and powder-free gloves when handling internal components. Never reuse gloves after you remove them because the surface contaminants on them might recontaminate the clean parts.
  • Always place the components on a clean, lint-free work surface.
  • Gather the necessary tools, supplies, and replacement parts (when applicable) before you begin the maintenance procedure.
  • Never overtighten the screws, and avoid excessive force when you reassemble components.

CAUTION

Before performing instrument maintenance, either shut down the mass spectrometer (MS) completely or place it in Standby mode as specified in the applicable procedure. Then, allow heated components to cool to room temperature (approximately 20 minutes) before you touch or service them.

CAUTION

To prevent corrosion, do not use nitric acid to clean metal parts.

IMPORTANT

Make sure that you do not introduce any scratches or surface abrasions while handling the components. Even small scratches can affect performance if they are close to the ion transmission path. Avoid using tools, such as metal pliers, that might scratch these components.

CAUTION

Heavy Object

Never lift or move the instrument by yourself; you can suffer personal injury or damage the instrument.

NOTE

Before you continue, read the precautions in Special notices, symbols, and cautions.
