2. When leak testing gas line connections, use a suitable electronic leak detector. Under no
circumstances should a soap solution or similar be used as this will contaminate the inlet and
the column.
3. There are potentially hazardous voltages present inside the OPTIC-4 control unit. To prevent
injuries and instrument damage, do not disassemble or modify it, or perform internal
repairs.
4. When working with glass liners, it is important to wear the necessary protective glasses to
shield eyes and skin from injury if the liner breaks or shatters on impact.
5. When working with capillary column, it is important to wear the necessary protective glasses
to shield eyes from injury if the column breaks or shatters on impact.
6. The operation of the GC inlet requires that it heats up rapidly to high temperatures. Parts of
the inlet may remain hot for some time after the unit is switched off or hangs up due to
internal fault. Care must be taken when working in the area of the inlet. It is especially
important to ensure that the inlet is cold (below 40°C) before changing inlet liners.
7. Do not tight or lose the top boss or the inlet bottom nut when inlet is at high temperature.
The threads can be easily damaged.
8. The OPTIC-4 EFC will be damaged when the inlet pressure exceeds specification. Do not
exceed maximum source pressure of 700 kPa.
9. Heating the column above the upper limits can significantly reduce column life. Make sure
that you are aware about the GC column maximum temperature limit.
