SUPER SESI, by FIT
User manual, Revision 2.0
If the vial holder is pressurized, depressurize it. For this, make sure that the syringe is not
connected to the syringe port and open the syringe valve 2 (up position).
Rotate the SUPER SESI locking levers 90 degrees to unlock the SUPER SESI onto the ion source
mount assembly.
Carefully pull the SUPER SESI out of the ion source mount. Use the handles.
CAUTION
Use the SUPER SESI handles to manipulate, lift or pull the SUPER SESI and to
press it against the Mass Spectrometer. Do not grab the sample line or other parts to
lift the SUPER SESI. Doing so could damage the sample line.
Turn the main switch off, and disconnect the power cord.
Maintenance

O (HPLC grade) and MeOH (HPLC grade)
•
Tweezers and a tray
•
Allen wrenches
•
MS Syringe pump
Cleaning the vapor path
In the event that the SUPER SESI gets contaminated and the normal high temperature cycle is
not sufficient to reduce persistent background contamination, the vapor path can be cleaned
with a cleaning liquid. Use a mixture of methanol and water 50-50 HPLC grade.
INTERESTING NOTE
The vapor path consists of those parts that are exposed to the vapors. This
includes the sample line, the ionization chamber, and the electrospray probe. These
parts are made of Stainless Steel (SAE 316), polished (in the accessible surfaces) and
coated with a passivation layer of amorphous silicon further functionalized to provide
the most inert surface available.
The electrospray probe can be cleaned with a swab or a Kimwipe soaked with liquid solvents.
Additionally, it can be immersed in an ultrasonic bath for further cleaning. For this, remove the
capillary and immerse only the part that is normally in contact with the sample vapors.
