and then insert the syringe.
Make sure that the end of the syringe is flush against the base and that the shaft of
the syringe rests in the cutout.
Tip! If the mass spectrometer will not be used for a length of time, we recommend that
it be left in standby with the ion source in place. If the mass spectrometer must be shut
down, follow these instructions. Do not turn off the roughing pump until after the turbo
pumps have spun down.
WARNING! Personal Injury Hazard: Make sure that the syringe is seated properly
in the syringe pump and the automatic syringe pump stop is adjusted properly to
avoid damaging or breaking the glass syringe.
WARNING! Puncture Hazard: Take care when inserting the syringe. The tip of the
syringe is extremely sharp.
