Safety and handling
Bear in mind the following safety considerations when performing
maintenance procedures:
See Appendix A for safety advisory information.
Warning:
The instrument components can be contaminated with
biologically hazardous materials. Always wear
chemical-resistant, powder-free gloves while handling the
components.
Warning:
To prevent injury, always observe Good Laboratory Practices
when handling solvents, changing tubing, or operating the instrument.
Know the physical and chemical properties of the solvents used (see
the Material Safety Data Sheets for the solvents in use).
Warning:
To avoid electric shock,
• do not remove the instrument’s panels. There are no
user-serviceable items inside the instrument.
• ensure that the instrument is in Standby mode before commencing
any maintenance.
Warning:
The probe and source can be hot. To avoid burn injuries, take
great care while working with these components.
Warning:
To avoid puncture wounds, take great care while working
with the source enclosure open, because the ESI probe tip is sharp.
Caution:
When performing maintenance inside the source enclosure,
ensure that the following criteria are met:
• Instrument is in Standby mode.
• LC flow is diverted to waste or set to off.
• Desolvation gas is turned off.
