Prohibited:
Do not place vessels containing liquid—such as solvent bottles—atop the
workstation or ancillary equipment or otherwise expose those units to dripping or
splashing liquids.
Spilled solvents hazard
Prohibited:
To avoid equipment damage caused by spilled solvent, do not place
reservoir bottles directly atop an instrument or device or on its front ledge. Instead,
place the bottles in the bottle tray, which serves as secondary containment in the event
of spills.
Flammable solvents hazard
Warning:
To prevent the ignition of flammable solvent vapors in the enclosed space of
a mass spectrometer’s ion source, ensure that these conditions are met:
• Nitrogen flows continuously through the source.
• A gas-fail device is installed, to interrupt the flow of LC solvent should the nitrogen
supply fail.
• The nitrogen supply pressure does not fall below 400 kPa (4 bar, 58 psi) during an
analysis requiring the use of flammable solvents.
When using flammable solvents, ensure that a stream of nitrogen continuously flushes the
instrument’s source, and the nitrogen supply pressure remains above 400 kPa (4 bar, 58 psi).
You must also install a gas-fail device that interrupts the solvent flowing from the LC system in
the event the supply of nitrogen fails.
Glass breakage hazard
Warning:
To avoid injuries from broken glass, falling objects, or exposure to toxic substances,
never place containers on top of the instrument or on its front covers.
High temperature hazard
Warning:
To avoid burn injuries, avoid touching the source ion block assembly when
operating or servicing the instrument.
