SUPER SESI, by FIT
User manual, Revision 2.0
General safety precautions and important notes
CAUTION
Do not perform any servicing that is not contained in this manual. In order to
avoid injury or damage to the instrument,
do not perform any servicing that is not
specified in this manual unless you are qualified to do so
.
CAUTION
Some parts of the SUPER SESI are heated for optimum performance. The
sample line and the ionization chamber are heated by electric resistors. The
electrospray probe can be heated by thermal conduction. These parts may cause burns
if touched.
Allow heated components to cool before touching them, and prevent other
persons to touch them
.
CAUTION
The tip of the electrospray silica capillary is very sharp and small. It can
puncture the skin, and it can be harmful to the eye.
Handle it with care and wear safety
glasses when handling the silica capillary.
CAUTION
The recommended electrospray liquid is high purity water with 0.1% formic
acid, but other solvents can also be used, including flammable solvents such as
methanol or ethanol. Use care when handling these solvents. Also,
be cautious when
handling the system in the presence of flammable materials
. The SUPER SESI could
produce small glow discharges that could ignite flammable atmospheres.
CAUTION
The SUPER SESI uses the high voltage that is provided by the Mass
Spectrometer. The SUPER SESI incorporates three high resistors (1 GOhm each) to
reduce the currents down to 0.03mA in the event that an electrode is exposed to ground
or to a person. This current is well below the hazardous threshold and the threshold
that can be felt by a human. Nevertheless,
to prevent damage to the instrument, the
electrodes should not be touched when the voltage is applied
.
IMPORTANT NOTE
The SUPER SESI is a very sensitive instrument. It is very vulnerable
to contamination, which can be observed as background signals. Even if no chemically
hazardous substances are used,
always use gloves when handling the SUPER SESI to
avoid contaminating it.
