to change the ion source.
When the instrument is in Standby mode:
• The source interface is ON, the drying gas remains heated, and nebulizer
flows are maintained.
• The source and ion optics voltages are turned OFF, and the mass
spectrometer is not sending spectra to the computer.
• The LC/MS high voltage electronics are ON.
• For APCI and multimode sources: The vaporizer gas heaters are turned down.
• For the Agilent Jet Stream (AJS) source: The sheath gas temperature, drying
gas flow, and drying gas temperature are reduced.
• The spray chamber high voltages are turned OFF.
• The mass spectrometer stop generating spectra.
