IMPORTANT
• Prepare a clean work surface by covering the area with lint-free paper.
• Put on a new pair of lint- and powder-free gloves before starting each of these
removal, cleaning, and reinstallation procedures.

and API source housing can severely burn you.
• Before removing the probe or API source housing, allow the part to cool to room
temperature (approximately 20 minutes) before touching it.
• If the mass spectrometer connects to an LC system, leave the solvent flow from the
LC pump on while the probe cools to room temperature.
