Lamp
Enables the selection of different lamp types you may have purchased to use with your instrument.
Ensure that the lamp selected is the same as that fitted in your TIGER. If not, select the correct lamp
from the options provided.
If you have purchased the instrument with the MiniPID 2 Lamp (Argon) 11.7eV
(LA4SM700), please take the following into consideration before using the lamp:
1. It is important for the lamps to be stored in their desiccated vials in cool
conditions (15-25°C).
2. The lamps should not be used in:
• Chemically severe environments, i.e. those containing significant
concentrations of acids and strong solvents such as
dichloromethane.
• Conditions of condensing humidity; always pass dry cool air through
the instrument before storage. For long storage periods, remove the
lamp and return it to the desiccated vial.
• Physically severe environments: large temperature changes may
initiate lamp failure.
11.7 eV lamps may not strike / illuminate first time, resulting in a ‘lamp fail’
alarm on the TIGER instrument, particularly if the lamps are unused for an
extended period. In case of a lamp fail alarm, please switch the instrument off
and then on again. Several start cycles may be required.
11.7 eV lamps have a relatively short life partly due to the type of lamp window
material. Prolonged exposure to airborne moisture slowly degrades the lamp
window. The lamps should therefore be removed from the TIGER and stored in
their desiccated vial when not in use.
11.7 eV lamps have quite different characteristics to the standard 10.6 eV lamps.
